Aluminium alloys are widely used in fabrication due to their versatility, strength, and corrosion resistance. Different alloys provide unique properties that make them suitable for various applications, from construction and automotive to aerospace. Choosing the right alloy is essential for achieving the desired results, which is why any experienced aluminium fabrication company in Dubai carefully selects the appropriate material for each project. Here are seven common types of aluminium alloys used in fabrication.
1000 series:
The 1000 series alloys are made of 99% or higher pure aluminium, offering excellent corrosion resistance and high electrical and thermal conductivity. However, they have low strength compared to other alloys, making them ideal for applications where strength isn’t the main priority, such as electrical conductors and chemical processing equipment. These alloys are easy to fabricate and weld, offering a cost-effective solution for non-structural projects.
2000 series:
The 2000 series aluminium alloys contain copper, giving them high strength and excellent machinability. However, they lack corrosion resistance, making them more suitable for projects where exposure to moisture or chemicals is minimal. 2000 series alloys are often used in aerospace applications due to their high strength-to-weight ratio, providing durability in lightweight structures.
3000 series:
The addition of manganese to 3000 series alloys provides moderate strength, excellent corrosion resistance, and improved workability. These alloys are commonly used in food and beverage containers, roofing sheets, and other applications requiring corrosion resistance. 3000 series alloys are relatively easy to form and weld, making them versatile options in aluminium fabrication.
4000 series:
4000 series aluminium alloys contain silicon, which lowers the melting point, making them ideal for welding and brazing applications. The addition of silicon also improves the alloy’s wear resistance. These alloys are commonly used in automotive components, such as engine parts and radiator tubes, where strength, thermal conductivity, and heat resistance are essential.
5000 series:
5000 series alloys include magnesium, making them highly corrosion-resistant, lightweight, and strong. These alloys are ideal for marine and structural applications, where exposure to harsh environments is a factor. The 5000 series is widely used in shipbuilding, pressure vessels, and outdoor structures due to its durability and weldability.
6000 series:
6000 series alloys combine magnesium and silicon, offering good strength, corrosion resistance, and workability. This series is commonly used for structural applications and in the construction industry. Aluminium fabrication companies often prefer 6000 series alloys for architectural projects, windows, and frames due to their versatility and ease of machining.
