Working with aluminium in your sheet metal fabrication project offers several advantages, including corrosion resistance, thermal and electrical conductivity, as well as its strong properties. So it’s no wonder it’s used in a variety of applications.
Well, we have all the answers and more in our blog below. Find out the top uses of aluminium, as well as why it’s a popular metal and even the potential drawbacks of using it.
So…what are the top 10 uses of aluminium?
We know that many companies appreciate the benefits of using aluminium. But just what industries do they operate in, and why is it a popular choice?
1. Architectural
Aluminium provides both strong and lightweight qualities – with an excellent strength-to-weight ratio. This makes it easier to fix buildings. For example, it uses fewer fixings than architectural projects utilising steel would need.
Moreover, it is easier to fabricate, which means it can be folded to fit any desired style or shape – suitable for architects and those in the construction industry looking to utilise it in a specific and complex project.
2. Consumer goods
Aluminium is easy to handle and efficient to manufacture – which is why it’s a popular choice when it comes to consumer goods. This might include the manufacturing of flat-screen TVs, laptops, mobile phones, and even some items of cookware.
What’s more, aluminium has a polished finish which makes it look aesthetically appealing; providing a modern and sleek look that remains timeless.
3. Electrical uses and power lines
Thanks to its low density, aluminium is commonly utilised in electrical applications. As it is a lightweight material, it’s ideal for power lines that span long distances.
Moreover, it’s easier to merge aluminium with wires as it is more ductile – which makes it a popular option over metals such as copper.
4. Packaging applications
Again, as a result of it being lightweight, flexible, and recyclable, aluminium is often utilised in packaging applications for the food industry. For example, in cans that hold food.
It is also hygienic and non-toxic so keeps the smell of food contained – ultimately preventing unwanted aromas.
5. Reflectivity and foil uses
Aluminium has a high level of reflectivity, which means it’s able to bounce back a large proportion of light – without needing to have additional coatings.
This means it’s a more cost-effective metal type to use when it comes to manufacturing mirrors or lighting fittings, which need reflectivity to function or for aesthetic appeal.
6. Transportation
In transportation and the manufacturing of transportation vehicles, aluminium is also a popular choice. It is lighter than other metals, making it an ideal option for reducing fuel emissions and thus enabling a higher level of energy efficiency.
Again, thanks to its lightweight properties, it increases the safety of transportation vehicles and reduces the risk of injury, as it has a higher level of energy absorption.
7. Ships
Again, with its high weight-to-strength ratio, aluminium is also a widely chosen material for help with ship manufacturing.
Ships made with aluminium will have a lower overall mass, allowing for more cargo – meaning more people can be loaded onto the vessel. Ultimately, this reduces the amount of trips these ships need to take to carry every load, so makes processes involving them more efficient.
8. Medicine and health care
As a lightweight material, aluminium is ideal for medical applications. This includes medical equipment such as wheelchairs, operating tables, and dental chairs – as it makes them easier to manoeuvre.
Aluminium is also non-toxic, which makes it safer to use when it comes to surgical instruments and other essential medical devices.
As a result, aluminium is most popular with manufacturers that are trying to obtain recognition as being eco-friendly – as they can say their packaging is 100% recyclable if they use aluminium.
10. Aircraft engineering
With its lightweight properties, strength, and high resistance to corrosion, aluminium is also an ideal material to use when it comes to aircraft engineering. Aluminium offers resistance to UV damage, which is why it is most suitable for aircraft construction.
Aerodynamic designs can also easily be made with aluminium as a result of its flexible formability – meaning they can easily be shaped and molded into complex aircraft components.
Uses of aluminium: FAQs
Does aluminium get rusty?
No, aluminium doesn’t get rusty because it doesn’t contain iron. But it does have the potential to corrode. More specifically, it corrodes when exposed to both oxygen and moisture. This is a process called oxidisation.
If you’re interested in learning what metals rust, you can check out our blog.
Why is aluminium preferred over other metals in fabrication projects?
There are many advantages to using aluminium in metal fabrication projects. For example, some key advantages it offers are:
Strength-to-weight ratio: Even though aluminium is a lightweight material, it is able to withstand considerable amounts of stress, making it a strong metal to use.
Corrosion resistance: Thanks to the protective oxide layer it creates, it resists corrosion so doesn’t require additional treatments.
Versatility: It’s easy to mould aluminium into a variety of shapes, so it’s perfect for complex projects that require specific shapes.
Sustainability: In terms of sustainability, aluminium is able to be recycled again and again – without damage or loss to its properties.
What are the disadvantages of using aluminium?
Obviously, with any metal you choose for a fabrication project, there are going to be some drawbacks associated with it. For example, some challenges to using aluminium include:
Prone to fatigue: Over time, aluminium can be prone to fatigue from excessive loading, which can create cracks and other damage.
Reaction with acids: Certain chemicals can lead aluminium to discolour.
Poor health: When exposed to high levels of aluminium, it’s possible for this to cause health problems to an individual. For example, it can contribute to conditions like Alzheimer’s when it accumulates in the brain in large quantities.

When you work with us, our experts will be able to help your projects come to life with services such as laser cutting and powder coating, as well as much more.
The market of metal fabrication services can be hard to navigate, especially when it comes to choosing the right metal for your project.
Committing to thorough research is your best bet, but this can be hard to perform when managing a project and/or your business. And sometimes, you just need the answer to whether one metal is more effective than another – such as mild steel vs stainless steel.
If you’re currently in this position and don’t know where to start, we’ve got you covered in our blog below. We’ll discuss the difference between mild steel and stainless steel, their varying properties, and their applications.
What is mild steel?
Mild steel is a metal-containing iron (meaning it’s ferrous) and is widely regarded within the sheet metal industry as suitable for a variety of engineering applications. As it is a type of carbon steel that has a low amount of carbon, it makes it easier to shape and machine.
What is stainless steel?
A solid metal alloy, stainless steel is made of iron, carbon, and other types of metals – typically chromium, nickel, and nitrogen. This helps make it a metal that can endure corrosion more than other types, so is perfect for specific applications – such as cookware manufacturing and medical instruments.
Mild steel vs stainless steel: corrosion
Let’s take a look at the difference between mild steel and stainless steel when it comes to both types of corrosion properties:
Mild steel corrosion
Mild steel does not have corrosion resistance. In fact, mild steel has to undergo a galvanisation process to prevent it from corroding. This is the act of coating a metal with zinc to help it avoid rusting. If mild steel doesn’t get galvanised, it will likely need more maintenance as the metal could potentially be weakened.
Stainless steel corrosion
As the name suggests, stainless steel is corrosion-resistant (hence stainless). This is due to the chromium it contains. This typically amounts to 10% and reacts with the oxygen in the air to form a protective layer – which makes it resistant to corrosion and rusting.
Mild steel vs stainless steel: strength
Is stainless steel harder than mild steel? We’ll explore this and the strength of both below:
Mild steel strength
The tensile strength (the amount of force a metal can withstand before it breaks/stretches) of mild steel is usually between 400 and 550 MPa – so a fairly average level. Its yield strength (the amount of stress the metal can take before it begins to deform plastically) is around 250 – 350 MPa.
Stainless steel strength
As there are 100s of types of stainless steel, the strength of it depends on the type of alloy used and its condition. In terms of tensile strength, this typically ranges from 500-720 MPa. For example, 304 stainless steel can reach a maximum of 625 MPa, meanwhile, its yield strength is approximately 205 MPa.
Mild steel vs stainless steel: weldability
Weldability refers to a metal’s ability to be welded without cracking or causing other defects.
Read on to see the comparison of mild and stainless steel when it comes to the different types of welding:
Mild steel weldability
As a result of its low ductility, mild steel is flexible and therefore easy to weld. When welding mild steel, it’s important to wear proper PPE to avoid exposure to welding fume; this can cause health problems such as lung cancer.
Stainless steel weldability
Whilst stainless steel is weldable, it can be harder to weld than other types of steel – such as carbon steel. Generally, mild steel is easier to weld, but stainless steel can be welded using special arc processes, such as TIG welding.
Mild steel vs stainless steel: malleability
A metal’s ability to be shaped without cracking is called malleability. Below we’ll explore the malleability of both mild and stainless steel below:
Mild steel malleability
Overall, mild steel is much more malleable than stainless steel. Again, this is the result of its low carbon content, which makes it easy to shape and bend. As a result, it’s the preferred choice for complex metal–forming projects.
Stainless steel malleability
Grade 304 and 316 stainless steel are the most malleable types of steel available, as they have a high nickel content. This means they are more suitable to be shaped without cracking – making them ideal for precise and intricate applications.
Mild steel vs stainless steel: applications
Now we’ve explored the differences between mild and stainless steel when it comes to their properties, let’s dive into the applications they’re best used for:
Stainless steel applications
There are a variety of applications in which stainless steel can be used. For example, It’s used in cookware because it has high heat resistance – and is easy to clean. What’s more, in the medical industry, it is used to create medical instruments as it is easier to sterilise than other types of metals.
Mild steel applications
Mild steel is used in a variety of industries, including construction, manufacturing, and automotive. It’s a popular choice due to its weldability, and its ability to be cut and coated in a bunch of different ways.
Mild steel vs stainless steel: cost comparison
Finally, let’s take a look at the most important factor pertaining to using a metal – the cost.
The cost of mild steel
Overall, the initial cost of mild steel is cheaper than stainless steel. This is because of its simpler composition and availability. However, it’s important to factor in the cost of maintenance as it is prone to corrosion.
The cost of stainless steel
As mentioned, stainless steel is more expensive as a result of the added alloying elements. For example, the addition of chromium to aid it in providing ultimate corrosion resistance. But over time, it will require less maintenance because of this resistance.
So…which one is better?
Overall, the most suitable option for you between mild steel and stainless steel depends on what you plan on using it for. Whilst mild steel is easier to weld and malleable, it is prone to corrosion, whereas stainless steel offers the opposite factors.
Ultimately, if you’re looking for a low-cost and low-maintenance solution, mild steel that has been galvanised is probably your best bet.

Aluminium is a common metal used in a variety of projects. It’s economical and safe, as well as having several properties which make it incredibly versatile. After steel, it’s one of the most widely used metals, so it’s no wonder it’s a sought-after solution for different sheet metal fabrication services.
If you’re considering using aluminium in your next sheet metal project, you might be wondering what the specific advantages of aluminium are. Fortunately for you, we discuss this and more in our blog below…
So…what are the advantages of aluminium?
Aluminium is a commonly used metal, and it’s clear why when you explore its benefits. In fact, we’ve highlighted 11 we can think of below:
1. Corrosion resistance
One advantage of aluminium is its high level of corrosion resistance. After exposure to the air, the metal forms a thin oxide layer that helps to stop further oxidation. This layer also prevents the metal from being exposed to environmental damage, such as moisture, chemicals, or saltwater.
Aluminium is also a very good heat and electricity conductor. Whilst this might be less so than copper, aluminium benefits from being low in density, which makes it more lightweight and cost effective. This means it’s a popular choice for certain electrical applications – such as power transmission lines.
Thanks to its high thermal conductivity, aluminium enables more effective and quicker cooling within radiators, heat exchangers, and other electronic devices.
3. Highly reflective
As it has a high level of reflectivity, aluminium is particularly useful for light and heat management applications. As it reflects light and even infrared radiation, it’s ideal for lighting fixtures, solar panels, and thermal insulation.
With a high level of reflectivity, it helps reduce energy consumption within its applications, as well as better maintaining temperature control in both buildings and vehicles.
4. Non toxic substance
Some metals react poorly with food or beverages, and even release harmful substances. But, aluminium is non toxic, which makes it ideal for food storage and containers.
Moreover, in the medical industry, it is used within certain packaging and equipment, as it upholds a high level of hygiene.
5. Can be recycled
Thanks to aluminium’s non toxicity, it’s environmentally friendly, making it a recyclable material. This recyclability can even continue indefinitely, as it doesn’t lose any of its quality or properties. This means there is no need for raw material extraction.
Furthermore, recycling aluminium also requires much less energy than producing new aluminium from scratch – so it can lower carbon emissions and energy consumption significantly.
6. Extreme strength
Aluminium also offers exceptional levels of strength, whilst remaining lightweight. This means it’s perfect for demanding applications, especially as a preferred material in aerospace, automotive, and construction industries.
Alloys of aluminium can also be manufactured to match the strength of steel, whilst also being resistant to corrosion and environmental damage – something steel is not. Aluminium also maintains its strength in extreme temperatures – so it offers an enhanced level of reliability, longevity, and safety in a number of industries.
7. Ductile
Ductility is an often-sought-after property in metals, and aluminium has high levels of it. This means it can be stretched or shaped into a variety of shapes, such as thin wires and intricate forms – without being subject to cracking or breaking.
Thanks to this ductility, aluminium is easier to process via rolling and forging, meaning companies that use it can reduce production costs as well as material waste.
8. Impermeable
Being impermeable means a material does not allow gases, liquids, or light to pass through it – which is another ideal property of aluminium. As a result, this makes it a great barrier material.
Even in thin layers such as foil, aluminium retains this barrier, meaning its material usage can be reduced whilst upholding a high level of protection.
9. Paramagnetic
Paramagnetic metals have a temporary reaction to magnetic fields but do not uphold this magnetism once the field is removed. Aluminium is paramagnetic, so it’s a popular application in industries where non-magnetic materials are required.
For example, this includes MRI machines within the medical industry and other sensitive electronic devices. Unlike ferromagnetic metals, aluminium is not vulnerable to electromagnetic signals so it won’t cause interference – making it ideal for communication and shielding applications.
10. Noise-reducing properties
Aluminium also has exceptional noise reduction properties, so it’s considered a valuable metal within the construction and other industrial industries. It dampens vibrations and ultimately absorbs sound, so helps reduce levels of noise pollution in buildings, vehicles, and machinery.
Because of this property, aluminium is used as panels within architectural designs, helping to maintain a quieter environment in the home. What’s more, it enhances passenger comfort within cars as it minimises engine and road noise whilst in a vehicle.
11. Low in weight
As it is much lighter than other metals, such as steel or copper, using aluminium helps to reduce the overall weight of products. This is why it is commonly used within the aerospace and automotive industries, where less weight means an improvement in fuel efficiency and performance.
This level of light also helps to enhance the portable nature of certain consumer products, including electronics and packaging.
What projects should I use aluminium for?
Whilst there are many advantages to using aluminium, there are specific industries and projects it will have more suitability & uses in. For example:
Transport vehicles
Aluminium is lightweight, whilst also being strong and corrosion-resistant, which makes it perfect for the manufacturing of transportation vehicles. For example, it’s used in the mechanical parts of cars, such as the engine and suspension.
Construction and engineering
As a result of its sleek design – and the fact that it’s weather-resistant/durable, aluminium is used in window and door frames, as well as in beams and columns. Aluminium sheets are also utilised in roofing to provide protection against the elements.
Foil
Aluminium is also used to make foil by moulding the metal into a thin sheet. This is most beneficial for food packaging, as it can help to maintain the temperature of a food, and also within heat insulation for the same reasons.

Aluminium vs steel: what are the differences?
There are several differences between aluminium and steel. Let’s take a look at their properties in more detail so we can understand how both compare.
Physical state
Aluminium: The most abundant element on earth, aluminium is light and silvery-white in its appearance. Thanks to its aesthetic appeal – it’s ideal for use in kitchen appliances.
Steel: Steel’s physical state will vary depending on the treatment it undergoes. Typically, it comes in a range of colours. For example, steel containing heavy amounts of carbon will be dark brown in appearance, whereas stainless steel is shiny and silver.
Aluminium: Aluminium is the second most malleable metal, so it can be moulded into different shapes. In terms of malleability, aluminium is a more suitable option than steel.
Steel: Steel is still highly malleable, meaning it can be shaped into many different forms. Because of this malleability, it’s also easy to join steel together to make intricate shapes.
Ductility
Aluminium: Aluminium is the sixth most ductile metal in the world. So, it can be shaped into forms without risk of breaking, but there are still better alternatives out there.
Steel: Generally, steel is able to be ductile, but this depends on the variation you choose. Ultimately in terms of ductility, aluminium would be a better option.
Conductivity
Aluminium: Aluminium’s electrons can easily move between atoms making it a strong conductor of electricity.
Steel: Steel does conduct heat and electricity to a certain degree, but again, it depends on the variation of steel used. For example, stainless steel tends to be a poor conductor of heat as a result of its alloy structure.
Density
Aluminium: The density of aluminium is about 2,710kg/m3, a fairly low amount, which is why it is lightweight and easy to move.
Steel: Plain steel has a density of 7.85g/cm³, 7850kg/m³, making it a fairly dense metal. This makes it a sturdy and durable material for use in the construction and manufacturing of heavy-use objects.
Luster
Aluminium: Aluminium has a dull lustre, typically the result of a thin layer of aluminium oxide.
Steel: Whether steel has a lustre depends on the type you use. Mild and stainless steel have a shiny finish, whereas carbon steel does not.
Melting point
Aluminium: Aluminium has a melting point of 660 Celsius (°C).
Steel: Steel has a melting point of 1,205-1,370 Celsius (°C).
Tensile strength
Aluminium: The tensile strength of aluminium is 90 MPa but this can be increased to over 690 MPa for some heat-treatable alloys.
Steel: The tensile strength of steel depends on its variation but typically, high-grade steel has a high UTS of approximately 1,000 megapascals (MPa).
Corrosion resistance
Aluminium: Aluminium and its alloys have significant resistance to corrosion. But, when submerged in water it can be exposed to higher chances of corrosion.
Steel: Steel containing carbon is not corrosion-resistant, due to the higher chances of it experiencing oxidation. Stainless steel however is corrosion-resistant.
Overall, is aluminium stronger than steel?
Pure steel in general is stronger than aluminium, mostly because it is a much denser material. Furthermore, as aluminium is a high conductor of electricity, it is less resistant to corrosion, making it a weaker metal.
But, when considering which of the two metals is stronger, sometimes weight can factor into the equation. For example, aluminium has a better strength-to-weight ratio than steel, meaning that although more aluminium is needed to support the same load as steel, it would weigh much less.
Is aluminium cheaper than steel?
Whether aluminium is cheaper than steel depends on the type of steel you purchase.
For example, steel varieties like mild steel and carbon steel are cheaper than aluminium. However, stainless steel carries a heavier price tag than aluminium.
Aluminium: common applications and uses
The applications and uses for aluminium vary, but most commonly they are used in the following areas:
Infrastructure
As it is a low strength metal, aluminium is not an ideal material for building physical structures. However, it does have other benefits that make it desirable for the industry. For example, aluminium is commonly used to make roofing materials.
This is generally more specific to Australia where many people opt for roofing types such as tiles and shingles. As it is corrosion resistant, it makes it an ideal option to protect a home from severe weather conditions. What’s more, thanks to its lightness and thinness it contains very little heat – keeping a home cooler in the summer months.
Manufacturing
Aluminium is widely used in the construction industry for machine bearings. These are systems that assist an objects’ rotation within different types of machinery, including automobiles, planes, and electric generators.
Aluminium is an ideal option for machine bearings because of its corrosion resistance, which helps to minimise damage and ultimately saves money on maintenance, repair, and replacement costs.
It’s also a common choice for aircraft construction, mostly because of its resistance to UV damage.
Appliances
Aluminium is a significant conductor of heat, which makes it a great choice for the manufacturing of kitchen appliances that rely on generating heat, such as ovens, microwaves, and radiators.
It’s also used in handheld kitchen equipment, including pots, pans, and oven trays, because of its lightweight properties that make it easy to lift by an average user.
Steel: common applications and uses
Steel is also used in the same industries as aluminium, but they have different purposes. For example, in:
Thanks to its significant strength, versatility, and cost-effectiveness, it’s a popular option for the construction of the above pieces of infrastructure.
Manufacturing
As mentioned, because of its high tensile strength and low cost, steel is a popular choice in the manufacturing industry.
For example, in ship manufacturing, high tensile steel is typically applied to areas of the ship that are exposed to larger amounts of mechanical stress, as well as the deck and bottom regions of larger tankers.
Transportation
In the transportation industry, most journeys and means of traveling are made possible because of steel. In cars, steel is a common choice for machine bearings and pipework, as well as car rims.
It’s also used in many car engines because it can withstand high temperatures and varying pressures.
Appliances
When it comes to kitchen appliances, stainless steel is predominantly used because of its finish, as well as its higher levels of resistance to types of corrosion, such as rust.
But, pure steel is also used within the industry, predominantly for washing machines, as it makes them easier to repair and maintain than those using plastic components.
Aluminium vs steel: FAQs
Aluminium vs steel – which lasts longer?
Aluminium and steel are both known for their durability and strength. Whether one lasts longer than the other also depends on the specific applications either are used in. However, aluminium will most likely last longer than regular steel because of its corrosion resistance.
Steel is heavier and stronger than aluminium, making it a better choice for heavy duty projects and purposes. Meanwhile, aluminium is more flexible and bendable than steel, making it ideal for projects involving shaping.
Which is better for an individuals’ health – aluminium or stainless steel?
Exposure to steel and aluminium will not be extremely harmful for an individual to experience, but it does depend on what the metal is being used for.
For example, when it comes to food preparation and cooking, stainless steel is generally considered to be a safe option. This is for a number of reasons, including:
Reactivity: Aluminium is more likely to react with acidic foods if used in excess, which ruins the taste of food and affects nutritional value.
Oven safety: Stainless steel is oven safe whereas aluminium isn’t.
Dishwasher safety: Stainless steel is dishwasher safe whereas aluminium isn’t.

What is rust?
Rust is a chemical compound made from iron and oxygen. It occurs when a specific type of metal is exposed to oxygen and moisture – such as humidity in the air. The iron atoms in the metal respond to the oxygen and moisture in the air by forming an iron oxide, also known as rust.
Put simply, rust is a form of corrosion that can happen to any iron-containing metal. Reddish-brown in appearance, the texture of rust will begin rough, and eventually wear in time and become flaky.
Why is rusting a serious problem?
Rusting can be a serious problem for those working in industries that rely on the application of different types of metals to form structures, or as part of a manufacturing process. These reasons might include:
Structural damage
As a result of the wear and tear rusting creates, it can cause damage to any structures being manufactured with iron-containing metals. For example, as time goes by, the rust will replace parts of the metal with a flaky powder instead which ultimately makes them weaker.
This can cause problems for structures such as bridges or automobiles, which rely on the strength of the metal they use to hold a considerable amount of weight.
Reduced inefficiency
In addition to the damage it can cause to metal structures, rust can also increase the likelihood of inefficiency in products that use metals with iron in them. For example, in some metal structures, magnetism is a key property to ensure it delivers its purpose.
This includes medical equipment, such as hospital water infiltration systems – which use magnetism to change the physical and chemical characteristics of the water to make it safer. If rust occurs in these systems it will decrease the levels of magnetism in the metals they use. Subsequently, the systems will fail to work as well and won’t be able to produce the same results as they did initially.
Costly
Rust in metal systems can also cause problems when it comes to the cost spent on repairing them. For example, companies that rely on iron-containing metal (or otherwise known as a ferrous metal) structures will have to account for the possibility of rust occurring.
There are several different types of metals that rust, including:
Steel
Steel is an alloy of iron and carbon, so it is prone to rusting. Typically, steel that has cheap production will also be more likely to rust than steel that has been manufactured to a high-quality standard. But it also depends on the environment the steel is located in. For example, steel is more likely to rust in acidic conditions – such as certain mining operations, than alkaline conditions – like seawater.
Cast iron
A combination of iron and carbon, cast iron is likely to rust despite its resistance to wear and tear. Cast iron is typically used in cooking for manufacturing skillets. If it’s left too long in water, such as if the user is soaking it after cooking, it can cause it to rust. To avoid this, it might have a protective coating, such as a carbonised oil called ‘seasoning’.
Another alloy of iron and carbon (albeit, a very low amount), wrought iron will likely rust if exposed to moisture and oxygen. Wrought iron is more difficult to produce than cast iron, as it is made by heating and moulding the iron within it. But it also has a smaller chance of rusting than cast iron, so might be the best option to use out of the two.
Which metals do not rust?
Fortunately for sheet metal fabrication projects, there are still a number of metals that do not rust, including:
Stainless steel
Unlike normal steel, stainless steel does not rust. Whilst it does actually contain iron, it also contains chromium – a corrosion-resistant material. When the stainless steel reacts with oxygen, it creates a protective oxidised layer. As the iron doesn’t get a chance to be exposed to oxygen or moisture because of this layer, it therefore won’t rust.
Aluminium
As it contains no iron, aluminium will not rust. It is a standalone element on the periodic table that contains nothing but itself. That’s why it is commonly used in outside/outdoor projects and sculptures, such as pergolas and verandas attached to a property.
Copper and bronze
Bronze is a metal that does contain iron but only in small amounts. A mixture of copper and tin, bronze can react to oxygen but in different ways. For example, it might deteriorate as time passes. Meanwhile, copper is a completely pure element on the periodic table and contains no iron, so it does not rust either.
How do you prevent metals from rusting?
Fortunately for sheet metal fabrication companies and other businesses that use metal in their manufacturing, there are ways you can prevent metals from rusting.
Apply a powder coating
One way you can prevent metals from rusting is by applying a powder coating. A powder coating has excellent resistance to corrosion as it creates a barrier between the metal surface and oxygen/moisture, meaning it’s less likely to rust.
Better yet, it’s a much more cost-effective solution compared to liquid coatings, because it has more longevity and will therefore require less maintenance and upkeep.
Galvanise the metal
Galvanising metal is the process of applying a layer of zinc to steel or iron to prevent corrosion. If the zinc coating is scratched, the exposed steel or iron will still be protected from rusting by the remaining zinc.
Similar to powder coating, galvanising metal creates a barrier that prevents the metal from being exposed to oxygen and moisture, and therefore prevents rust occurring.
Paint the metal and store it properly
As with the above solutions, painting the metal will act as a barrier that protects the metals from rusting.
Paint also acts as an electrical insulator; slowing down the process of corrosion by slowing the flow of the current. This current encourages a reaction that stimulates corrosion.
What metals rust: FAQs
Can you remove rust from metal?
Yes, you can remove rust from metal – it just depends on the severity of it and how much it has affected the material. Some ways you can remove rust from metal include:
Vinegar: This solution is best used on steel or on metal coated in significant rust. Individuals can remove the rust once soaking the metals affected in a vinegar bath overnight. Or, if it cannot be submerged in vinegar, you can soak a cloth and wrap it around the rusted area instead.
Potato and soap: You can also use potato and dish soap to remove rust from metal. Slice a potato in half and cover it with dish soap, then rub it on the rust. This creates a chemical reaction in the rust that makes it easier to remove.
Lemon and salt: Small amounts of rust can be removed with a combination of lemon and salt. You can do this by coating the layer of rust with salt, and then squeezing lemon juice on top. Let the coating sit for a little bit, then scrub it with the rind of the fruit. Repeat until the rust disappears.
Can you paint rusted metal?
In theory, it is possible to paint rusted metal, but it’s advisable not to.
Ideally, you should remove the rust first and then paint, as a coat of paint can be easily damaged or flake off if applied on top of the rust.
What are the three types of rusting?
There are three different types of rusting that can occur, including:
Red rust: Red rust is the most common type of rust you can find on metals.
White rust: White rust can form when zinc in metals reacts with oxygen.
Yellow rust: Yellow rust is often found on copper and brass surfaces.

What does it mean when a metal is magnetic?
When a metal is magnetic, it creates a magnetic field that has attractive and repulsive forces on a magnet.
Magnetism in metals is caused by an uneven distribution of electrons in atoms. As this distribution moves and rotates irregularly, it shifts the charge inside the atom back and forth. As a result, magnetic dipoles (a closed loop of an electric current) are created.
What are the types of magnetism?
Before we dive into the types of metals that have magnetic properties, let’s first explore the different types of magnetism:
Ferromagnetism
Ferromagnetism is the strongest type of magnetic behaviour, as well as the most common. Materials that have these magnetic properties showcase attraction to magnets and can be magnetised. Those with ferromagnetic materials have unpaired electrons in their atoms.
Antiferromagnetism
As the name suggests, antiferromagnetism is the opposite of ferromagnetism. In this type of magnetism, electrons within a material come together to form a chain of oppositely charged particles, despite the materials not appearing to have any magnetic properties. But, as the temperature rises, the electrons will randomly scatter and become magnetic. This is known as the Vanille temperature.
Ferrimagnetism
This type of magnetism occurs in solid materials where the individual atoms align themselves in an unplanned way. It is similar to ferromagnetism, but it differs in the fact that the atoms might align themselves parallel, in the same direction, or in opposite ways rather than in just one direction.
Paramagnetism
Paramagnetism happens when there is a presence of unpaired electrons – which act like tiny magnets – within a material, that causes a weak attraction to a strong magnet. Examples of paramagnetic materials include oxygen, aluminium – and other rare earth elements from the periodic table.
Diamagnetism
Diamagnetism is the complete opposite of paramagnetism, in that in diamagnetic materials, electrons are paired and none are freely available. As they are orbiting in opposite directions, they produce no magnetic field. Meaning, diamagnetic materials are always repulsed and will be repelled in any magnetic field.
Magnetic metals list
Let’s take a look at some of the most commonly used magnetic metals below:
Steel
Steel is highly susceptible to metal attraction so is a ferromagnetic metal. However, the properties of the steel in question affects how magnetic it is. For example, if it has smaller grain sizes – this can enhance its magnetic properties. Or, if the nickel level rises in a steel alloy, this can make it more magnetic.
Iron
Iron is an abundant metal and easily sourced – which is why it’s commonly used within a variety of industries. It is a ferromagnetic material which makes it useful for applications in electrical and electromechanical devices, such as in the transportation industry to help make electric motors.
Cobalt
Cobalt is another ferromagnetic metal, found within the Earth’s crust in a chemically combined form. It’s considered to be a valuable type of metal as it can be used in many portable electronic devices that are a part of our daily lives. This includes telephones, tablets and laptops.
Nickel
Nickel is a ferromagnetic metal that is silvery white in appearance. It’s considered to be tougher and harder than iron. As it resists corrosion, it is used to plate other metals as a way of protecting them from the elements. What’s more, it’s also used to make alloys such as stainless steel.
Gadolinium
Gadolinium is a paramagnetic metal that is only temporarily magnetised when placed in the vicinity of a magnetic field. This is the result of its structure allowing for a bigger number of unpaired electrons. Gadolinium is most commonly known for being used to make images clearer in an MRI scan.
Dysprosium
Dysprosium has different magnetic properties depending on the temperature it is kept at. If it is below 85K, it is considered to be ferromagnetic, but is antiferromagnetic when between 85 and 179K. Anything above that and it is a paramagnetic material.
Terbium
When it is below 219K, terbium is a ferromagnetic material, but when above this temperature, it turns into an antiferromagnetic state. Terbium has an extensive amount of uses, including in low-energy lightbulbs and mercury lamps. It can also be used in the science industry to improve the quality of medical x-ray images.
Which metal has the strongest magnetism?
The metal with the strongest magnetism is Neodymium iron boron (NdFeb), which is made from an alloy of neodymium, iron, and boron.
This alloy was developed in 1984 and is the most widely used permanent magnet made from rare earth materials.
Which metals are not magnetic?
There are several metals that aren’t magnetic – meaning they cannot be made into magnets and will not be attracted to magnetic fields. These include:

Since the 1960s, Computer Aided Design (CAD) has been utilised by both designers and engineers to help create, amend, and optimise product designs. This helps to increase the quality of the product – and ultimately achieve a higher level of user/customer satisfaction.
At Salamander Fabrications, our CAD design service is one of the vital beginning stages within our sheet metal fabrication process – forming part of nearly every project we work on.
So, we know better than most how useful CAD software can be when we provide our metal fabrication services. That’s why we’ve created our own blog below to highlight the pros of using CAD. Read on to find out more about the advantages of CAD, who uses CAD software, and some drawbacks you might encounter.

Prior to the introduction of CAD, designers would mock up the design for a product on paper – painstakingly drawing every detail. When a feature needed to be modified, the designer would have to redraw the entire product.
But, thanks to the many features of CAD, businesses that use it can design mock-ups which can then be modified, reviewed, and shared in real time. This helps streamline the design process and enables real-time collaboration amongst team members – but these aren’t the only advantages the service offers…
The advantages of using CAD
As mentioned, there are a vast amount of advantages you can receive when using CAD software – or when you work with a business that does. Let’s explore the benefits of CAD in more detail below:
Comprehensive and simple designs
When it comes to product drawings, some designs can be much more difficult to comprehend than others. For example, architectural designs might be harder to envisage without the use of 3D modelling due to the complexity of their structure.
But, when using CAD designs, individuals can better visualise a manufacturing project and understand the vision of the designer thanks to the 3D models they can create, which shows every angle, surface, and view of the product.
Minimises the chance of errors occurring
Using CAD software can also help minimise the chance of errors occurring. This is because of the many features the software provides, including:
Design alteration
Design precision
Design tools, such as animations
Simulation capabilities
All of the above means users of CAD software can make adjustments to their products with ease, without having to start a design from scratch. Moreover, if a design has an unmistakable flaw, it will likely be noticed during the 3D model stage, and not when the product is in its final stages of design – which is when it’s more difficult to modify.
Increased productivity and time efficiency
Another advantage of using CAD software is that it can help increase productivity and efficiency within a business. We’ve already mentioned how mistakes can be fixed more quickly using CAD software than with a design that has been drawn, but it also has several automation features that streamline the process.
For example, it can fill in portions of a building’s design plans with its automated drafting tools. Or, it can even create design plans based on preset parameters and templates. So, instead of starting a design from the very beginning, you can save time by using a template to provide the foundations of the structure.
Easier integration with manufacturing processes
CAD software also allows for easier integration with other manufacturing processes. It can be used in conjunction with CAE (computer-aided software engineering) which can give the designer/engineer a better idea of how the product will work in the real world.
For example, CAE tools can simulate how a product will react in different conditions, such as with heavier loads and environmental conditions. When used with CAD, the engineering/design process is much smoother because users are able to develop the products more quickly than with physical designs.
What are the drawbacks of using CAD?
It’s no secret – CAD has definitely improved the working lives of designers and engineers all over the world. But, whilst its technology has helped businesses in a manner of ways, it still comes with some drawbacks that you need to be aware of, including:
Infrastructure limitations
One drawback that can occur when using CAD software is that it is used online. And, with any IT application or software, it can be prone to technological crashes which could disrupt the design or cause data loss.
To avoid this, ensure you save your work frequently, and if you can, use an auto-save feature.
Consistent training is needed
Consistent training with CAD software is a must if you want to create seamless designs. But, it does mean investing time and money in the development of staff to ensure they have the qualifications to use CAD.
If you want to save money, consider asking one of your trained experts to guide others into using the best practice with CAD software.
Different formats
Different CAD software programmes will also have different IT requirements – making it more difficult to share and collaborate on designs if your engineers are using various devices. To minimise this issue, ensure your equipment is frequently updated and troubleshoot common problems when you can.
CAD software might be the future of manufacturing, but no piece of software is perfect. But being aware of the potential drawbacks of using CAD can better equip businesses to handle them if and when they do occur.
FAQs
Who uses CAD software?
It might seem industry-specific, but CAD software is actually utilised by many people within a variety of professions. For example, CAD is used by:
Engineers: CAD software is mostly utilised by engineers, as it gives them the precision and accuracy that allows them to get a better picture of how the product they’re manufacturing will work in a real-life environment.
Product designers: Whether it’s to design smaller components of a piece of equipment for businesses, or to create a product for consumers, any type of product designer can benefit from using CAD software. Mostly, they’ll be able to take advantage of real-time modifications without having to start their design again.
Graphic designers: It might seem surprising, but graphic designers can also benefit from using CAD software. They can use it to help clients visualise a product; and take advantage of the many tools it offers, such as the ability to add digital effects, different backgrounds, and even animations.
What is the best CAD software?
There are a variety of CAD software applications available. Finding out which one will suit your needs the best depends on your industry, business, products or services. When assessing which software is best for your business, ensure you consider factors including:

Welding might sound like a fairly simple process, but in reality, it’s a technical craft that requires a specific skill set; including high levels of attention to detail and precision.
What’s more, the individual performing the process needs to be aware of what welding joints to use so that they can guarantee a high-quality weld. Since there are several different types of welding joints to choose from, it’s important to pick the right one for your weld, since different ones offer different qualities.
That’s why we’ve highlighted the five most common welding joints in our blog below. Read on to find out what they are, their applications, and how to choose the right one for your project…
Interested in our welding services? Get in touch at 01484 843599 to find out what we can offer your business.
1. Butt joint weld
Starting with one of the most common types of joints – the butt joint weld is where two flat pieces of metal are aligned in the same plane at an angle before the weld begins. Butt joint welds have many variations, including:
Square
V-groove
Single bevel
What variation a welder chooses for this joint depends on the type of weld being produced. For example, square groove welds are better for materials being welded which are moderately thick.
What are the common applications of a butt joint weld?
Butt joint welds are most commonly used in sheet metal fabrication, in the fabrication of structures, such as bridges and parking garages, as well as piping systems. They are also used in the transportation industry for the manufacturing of car frames and exhaust systems.
2. Lap joint weld
A lap joint weld is a similar process to a butt joint weld, but instead of joining the metals side by side, they are placed so they overlap each other. With these types of weld, you can either provide a full lap joint or a half lap joint.
In a full lap joint, no materials are removed from the piece joined – meaning the weld is a combination of both materials’ thicknesses. With a halving laps joint, material is removed from both pieces, so they can join together to create a thickness uniform with the rest of the weld.
Pros:
Better for aesthetic purposes as provides a neater finish
Have a large surface area for the weld
Cons:
The overlapping metals might not be suitable for all types of aesthetic applications
Correct welding speed must be used otherwise it can be prone to cracking
What are the common applications of a lap joint weld?
Lap joint welds are commonly used in sheet metal fabrication projects, as well as in the repair of metal structures. They are also used within the aircraft and spacecraft sector, to form structural components.
3. Corner joint weld
To count as a corner joint weld, two pieces of material in a weld must be joined at a right angle. This is so the materials ultimately form an L-shape.
To be classed as a corner joint weld, the metals must be joined together at a 90 degree angle. Any other angle would be considered a fillet weld.
Pros:
Can withstand a variety of materials
Offers a clean appearance so suitable for aesthetic projects
Can experience more bouts of wear and tear at its seams
What are the common applications of a corner joint weld?
Corner joint welds have proven popular in the sheet metal fabrication industry because they act as a focal point of stress, which makes them perfect for making boxes and frames.
4. Edge joint weld
Edge joint welds are similar to corner joint welds in that they help join two metals together. However, edge joints join the metal side-by-side. Depending on the application, the joint can be angled.
They’re often considered to be easy to assemble and a better alternative to corner welds – if an accurate fit is necessary.
Pros:
Fairly easy to assemble and master
No need to prepare materials before welding as the edges used are typically already smooth and even
Cons:
Can’t withstand heavy loads
Weld can struggle to penetrate all the way
What are the common applications of an edge joint weld?
As they are similar to corner joint welds, they have similar applications too. Edge joint welds are used in sheet metal projects, as well as piping where accuracy is essential.
5. Tee joint weld
A tee joint weld gets its name from assuming the shape of the letter ‘T’, and involves welding two perpendicular pieces of metal together.
They’re considered to be a type of fillet weld, and are faster and easier to produce than other welding joints in the list.
Pros:
Simple and quick to create
Can withstand stronger materials
Cons:
Must prepare edges if materials are thicker
Are more prone to corrosion
What are the common applications of a tee joint weld?
Tee joint welds are most commonly used in equipment manufacturing – for example, within packaging machinery. They are especially useful for those working with thin materials such as plates or sheets.
Types of welding joints: FAQs
What exactly are welding joints?
Welding joints refer to the point or edge where two (or more) metals are fused together.
The process of welding dates back to 3000 B.C., so it makes sense that within this time we’ve developed higher standards around the process. That’s why small details, such as choosing the right welding joint are very important, as they can impact the quality of the weld.
How do you choose the right welding joint for your project?
To choose the right welding joint for your project, ensure you consider the following factors:
Materials: Assess the materials you will use in your weld. This will indicate what strength of weld joint you need. For example, if you’re using thicker materials, you might need to use a butt joint as they have good mechanical strength.
Welding process: You should also consider the welding process when you choose a weld joint. This is because some joints are more suitable for welding in certain positions than others.
Accessibility: Evaluate what the process of your weld will entail before choosing your weld joint. For example, if you have poor weld area accessibility, it’s best to pick a weld joint that is easier to access, such as the butt joint.

Mild steel is affordable, strong, and offers easy fabrication, making it a common material for metal fabrication services. If you’re still asking yourself the question ‘What is mild steel?’ – we’re here to help answer it.
In our blog below, we’ll dive into more detail regarding the material’s grades and typical applications, as well as the properties of mild steel.
What exactly is mild steel?
Mild steel is a ferrous metal made from a combination of iron and carbon – amounting to around 0.05% – 0.25%, making it known as a low-carbon steel.
As a result of this low carbon content, mild steel is more ductile and malleable, making it easier to work with when compared to higher carbon steels.
What are the properties of mild steel?
Mild steel has several properties associated with it – making it an affordable and versatile choice for those working in metal fabrication, welding, and powder coating services. Let’s explore some more below in more detail.
Chemical composition
As mentioned, carbon content is usually between 0.05% and 0.25%, which is considered low.
The rest of this material’s composition is mostly iron, with potential traces of other elements such as manganese, silicon, and phosphorus.
Mechanical properties
Mild steel has a moderate tensile strength, typically around 400-550 MPa (megapascals). This makes it strong enough for some structural applications, but higher carbon steels are still a much stronger option.
It’s also highly ductile and malleable too. So it can be stretched, rolled, and bent, as well as being able to withstand sheet metal folding and be shaped into various forms without breaking. This type of steel can absorb impact and shock well, making it durable under heavy loads or stress. It can also be hardened through heat treatment processes like case hardening.
Thermal properties
The melting point of mild steel is around 1,425 to 1,505°C.
It offers good thermal conductivity, making it suitable for heat exchanging applications.
Weldability
All of the different types of welding (including MIG, TIG, and spot welding) work well with mild steel, due to its low carbon content.
It typically does not require any special processes or equipment to undergo welding services.
Highly magnetic
Mild steel is highly magnetic due to its high iron content.
This is one reason why it’s commonly used in the motor industry and in other electrical equipment.
This is unless it is painted or powder coated. Powder coating services provide a hard wearing, water resistant finish that is not vulnerable to damage from chemicals or UV light. Find out more with our ultimate guide to powder coating.
Machinability
Mild steel is relatively easy to machine and fabricate using industrial methods such as laser cutting, drilling, and turning.
Mild steel grades
Mild steel is commonly classified under British and European standards – otherwise known as Eurocodes or structural steel design standards. These common mild steel grades are used in various industries depending on the required mechanical properties.
Let’s take a look at some mild steel grades in more detail.
Mild steel grade | EN 1.0038 / S235JR (EN)
Carbon content (approx):
0.12% to 0.20%
Properties:
Good machinability and moderate strength.
Typical applications:
Structural work in buildings, bridges, and general construction.
Mild steel grade | EN 1.0038 / S235JR (EN) / BS EN 10025
Carbon content (Approx):
0.25%
Properties:
Higher strength than S235JR. Good ductility.
Typical applications:
Large-scale projects like bridges and offshore structures.
There are several different projects and processes in which mild steel is used. For example, in:
Construction and structural applications
Mild steel is widely used in the construction of buildings, bridges, and other infrastructure to create components such as beams, columns and frames.
This is due to its high strength and ability to bear heavy loads. It can also be found in reinforced concrete structures as it is used to strengthen the structure and prevent cracking.
Automotive and transportation industry
Mild steel is a common material in the automotive and transportation industries. There are many parts of a vehicle that are often made from mild steel because it is easily formed and welded. This includes:
Body panels
Chassis and frames
Engine parts, such as brackets and supports
Interior decorations
It’s also widely used on our railways, and to create certain components of train bodies and undercarriage structures too.
Engineering and fabrication
Due to its excellent weldability, mild steel is used for fabricating metal structures, such as bridges, platforms, and frameworks.
It’s also used to create fasteners like nuts, bolts, and screws.
Machinery and equipment
Mild steel is a common material found in many areas of the agricultural sector. It is used to make parts for tractors, ploughs, and many other forms of farming machinery due to its durability and ability to handle heavy loads.
It’s also used to fabricate components for industrial machinery like conveyors, gears, and shafts.
Household appliances
Last but not least, mild steel is also used…within your home! A lot of the white goods in your household, such as your refrigerator or washing machine, will contain mild steel components.
It’s also commonly used in the production of metal furniture, like shelving units and bed frames. This is mainly due to the material’s durability and affordability.

Sheet metal folding (sometimes known as CNC press braking)
If you’re working with metals, you might have heard a variety of terms come up in your day-to-day communications. One of these terms will likely be non-ferrous, and ferrous metals – but exactly what are they, what’s the difference, and when do you use each type?
In this blog, we take a deep dive into a non-ferrous and ferrous metals list, discussing their features and properties to compare against each other. We’ll also discuss the role ferrous metals play within metal fabrication services.
What makes a metal ‘ferrous?’
What exactly makes a metal ‘ferrous’? Well, the key difference lies in the iron content. Ferrous metals (such as steel, cast iron) contain iron, making them strong, magnetic, and prone to rust.
Meanwhile, non-ferrous metals (such as aluminium and copper) do not contain iron, meaning they are non-magnetic and have higher corrosion resistance.
List of ferrous metals
There are an abundance of ferrous metals out there that are used on a daily basis. The most common ones include:
Mild Steel: Used to create structural beams, automotive parts, household appliances, machinery parts, and construction frameworks.
Carbon Steel: Usedto manufacturehigh-strength components like gears, shafts, and tools.
Stainless Steel: Often found in kitchen utensils and cooking equipment. Also found in medical instruments and components that require corrosion resistance.
Cast Iron: Can be found in engine blocks, pipes, manhole covers, machine parts, and other heavy-duty castings.
Wrought Iron: Commonly used to create decorative railings, gates, and furniture. It is used for its malleability and aesthetic qualities.
Tool Steel: Used forcutting tools, dies, moulds, and other high-wear parts due to its hardness and resistance to abrasion.
Alloy Steel: Applications includestructural components, aerospace parts, and automotive parts.
List of non-ferrous metals
Non-ferrous metals are just as important as ferrous metals when it comes to everyday usage. Typical non-ferrous metals individuals and businesses use include:
Copper: Commonly found in electrical wiring, plumbing pipes, roofing materials, heat exchangers, and (of course) coins.
Brass: Used in plumbing fittings, musical instruments, electrical connectors, decorative items, and hardware components.
Bronze: Itswear resistance and strength means bronze is commonly found inbearings, bushings, sculptures, coins, and marine hardware.
Nickel: Used in the production of stainless steel. You can also find nickel in batteries and electroplating.
Titanium: High strength-to-weight ratio means this is a popular material for aerospace components, sports equipment, and automotive parts.
Magnesium: Used in aerospace components, automotive parts, and portable electronic devices.
Silver: Most commonly found injewellery and coins, but can also be used in electrical contacts and cutlery.
Non-ferrous vs ferrous metals list of features
The presence or lack of iron content brings with it more differences between ferrous and non-ferrous metals. Let’s explore what this means when it comes to the reasons why these features make them appealing to certain projects.
Non-ferrous and ferrous metals play a significant role in metal fabrication services due to their strength, durability, and versatility. Below you’ll find some of the ways this ferrous metals list can be formed, fabricated, and worked on.
Cutting and shaping
Non-ferrous and ferrous metals can be cut and shaped using various methods such as shearing, sawing, laser cutting, and plasma cutting. Processes like this can create components for structural frames, machinery parts, and other custom products.
Welding and joining
Differenttypesof welding techniques, such as MIG, TIG, and spot welding are used to join non-ferrous and ferrous metals together. Ferrous metals offer excellent weldability qualities, making them a favourite for professional welding services and welders alike.
Machining
Turning, milling, and drilling are all examples of machining processes that are used to achieve precise dimensions and finishes. Non-ferrous and ferrous metals are commonly machined for parts that require high strength and precision.
Sheet metal folding
Sheets of non-ferrous and ferrous metals can be bent into the desired shape using CNC press brakes or folding machines. Sheet metal folding allows for accurate bends and angles, essential for manufacturing parts with tight tolerances. Folding durable and robust non-ferrous and ferrous metals maintains their strength and structural integrity.
Heat treatment
Heat treatment processes can be used to change the mechanical properties of non-ferrous and ferrous metals. These processes include annealing, quenching, and tempering – which are used to improve hardness, strength, and ductility.
Coating and finishing
Non-ferrous and ferrous metals often undergo coating processes like painting or powder coating services to improve aesthetic appearance and corrosion resistance. This is especially true for outdoor applications where durability and appearance are important.
Forming and fabrication
Sheet metal fabricationmayinvolve bending, rolling, or stamping non-ferrous and ferrous metals into various forms. These methods are used to produce sheet metal parts, structural sections, and other custom components.
Casting
Casting processes like investment casting and sand casting are used to create complex shapes from molten ferrous metals, like cast iron. The resulting cast ferrous metals can be used for engine blocks, pump housings, and decorative items.
