2A02 Aircraft Aerospace Aluminum Bar Forgings is a kind of alloy with high strength in hard aluminum. It is characterized by high strength at normal temperature and high thermal strength, which belongs to heat-resistant hard aluminum. The alloy has high plasticity during hot deformation. It has a tendency to form coarse grain ring in extruded semi-finished products, which can be strengthened by heat treatment and used in quenching and artificial aging. Compared with 2A70 and 2A80 heat-resistant forging aluminum, the corrosion stability is better, but it has the tendency of stress corrosion cracking, and the weldability is better than that of 2A70, and the machinability is good.

Alloy	Alloy Series	Main Features
2A02	Al-Cu-Mn	The heat treatment strengthened alloy, Al-Cu-Mg system, has high strength and plasticity, high heat resistance and corrosion resistance in artificial aging. It is used to manufacture aero turbojet axial compressor blades and other parts at 200 --300ºC.
