2618A Aluminium Alloy

Commercial Aluminium

2618A Commercial Aluminium Alloy

2618A - a strong aluminium alloy containing nominally 2% copper and 1.5% magnesium.

High-Temperature Service

The alloy is solution treated and artificially aged to achieve the T6 condition or with the addition of controlled stretching to achieve the T6511 temper. 2618A can be employed to a maximum of 300°C and retains mechanical strength relatively well to around 200°C and above. The alloy has a density of 2.75 g/cc.


2618A aluminium alloy offers good machinability and has fair resistance to atmospheric attack. It is a strong aluminium alloy and can be used to produce clad sheet and strip.

Typical Applications

Commercial applications for this engineering material include:

  • Aerospace components
  • Defence components
  • High technology applications

We stock 2618A in flats, round bar, plate, sheet and round tube.
