2A12 aluminum-copper-magnesium hard aluminum alloy raw material

Name: 2A12 aluminum-copper-magnesium hard aluminum alloy raw material
Rating: 5 (99 reviews)

Aircraft fuselage skin, wing ribs, load-bearing components of aircraft, and high-strength tooling substrates that withstand alternating vibrations.

2A12 is a Chinese high-strength Al-Cu-Mg duralumin equivalent to 2024. It has excellent fatigue performance and strong resistance to crack growth under alternating vibration, and T651 stress-relieved plate reduces spring-back in machining, so machined parts stay dimensionally stable.

Bare material has poor corrosion resistance and is difficult to fusion weld, so surface protection is normally used and mechanical joining is preferred.

It is mostly used for aircraft fuselage skins, wing ribs, aircraft load-bearing parts and high-strength mounting plates under vibration. It is not recommended for linear module bases that must withstand long-term high-speed reciprocating impact and need a stable micron-level datum.
