Aluminium is Lightweight
With its low density, aluminium is much lighter than many other metals like steel or copper, and despite this, it can be alloyed with other elements to achieve high strength, which is essential for structural applications. This high strength-to-weight ratio is particularly beneficial in applications where weight reduction is crucial, such as in transportation (automotive, aerospace), construction, and consumer electronics.

Aluminium is Environmentally Friendly
Did you know that approximately 75% of the aluminium ever produced is still in use today?
Often referred to as the ‘green metal’ in the field of metals, aluminium can be recycled over and over… almost infinitely! And its amazing recyclability characteristic ensures it can be recycled without compromising any of its unique properties or qualities, making it an incredibly sustainable material (the properties of recycled aluminium are no different to that of the primary metal). That means a car bumper can be turned into a ladder or a can into part of a garden chair!
Aluminium has Corrosion Resistance
Aluminium naturally forms a thin oxide layer on its surface that protects it from corrosion. This makes it ideal for outdoor applications and in environments where it may be exposed to moisture and other corrosive elements.
Aluminium is Versatile
Aluminium can be extruded into a wide variety of complex shapes. This means there’s greater flexibility in design and for creating custom profiles that meet specific requirements.
For example, designers can integrate different functions like screw ports, thread details, clip fits and hinge details into a single profile.
Extrusions can then be easily shaped, cut, drilled, machined, punched, bent and welded to fit a bespoke purpose.
Aluminium's Conductivity
Aluminium is a fantastic conductor of electricity and heat, which is particularly advantageous in electrical applications, such as in power transmission lines, and in heat exchangers and radiators.
Aluminium is an excellent heat conductor. Profiles can be designed to maximize surface area and thermal channelling. An example of this would be heat sync, where aluminium could be used to take heat away from a semiconductor.
Sections including thermal breaks can be used to lower heat conductivity. These can be made using materials less-conductive than the typical alloy. An example of this would be in the internal and external surfaces of a window.
These properties also mean that aluminium doesn't melt until at around 650°C, and does so without releasing any harmful gases. It's also non-combustible.
Aluminium’s Machinability and Workability
Aluminium is relatively easy to machine, cut, and shape, which reduces manufacturing complexity and costs. It can also be easily welded, brazed, and soldered.
Aluminium’s Aesthetic Appeal
Aluminium has a modern, sleek appearance and can be anodized or powder coated to enhance its look, which is desirable in consumer products and architectural applications.
These treatments help make the metal more durable and resistant to corrosion, whilst ensuring a quality finish on the final product that can fit the theme of almost any project.

Aluminium is Non-Magnetic
Aluminium is non-magnetic, making it suitable for applications where magnetic interference could be an issue, such as in certain electronic and aerospace applications.
As you can see, aluminium is a versatile and practical material for a wide range of applications, from industrial to consumer products. Want to know more about using aluminium for your metal needs? Get in touch to find out how we can help!
