Product Details

Aircraft Aluminum Grades: 2024

2024 aluminum coil belongs to Al-Cu-Mg series of aerospace aluminum alloys, with the following main features and applications. It is a kind of high-strength duralumin that can be strengthened by heat treatment. 2024 aluminum alloy has medium plasticity in quenched and freshly quenched states, good spot welding, and tends to form intergrain cracks in gas welding. 

The machinability of the alloy after quenching and cold hardening is good, and the machinability after annealing is low: Corrosion resistance is not high, often using anodic oxidation treatment. However, it is important to note that it is susceptible to stress corrosion cracking when exposed to certain environments. Therefore, proper surface treatment and corrosion prevention measures are recommended for long-term durability.

2024 Aircraft Aluminum Alloy Coil

2024 aluminum coil is mainly used to make a variety of high-load parts and components (but does not include stamping parts forgings) such as aircraft skeleton parts, skin, frame, wing ribs, wing spars, rivets and other working parts below 150℃.
