Prodsuct Introdsuction

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 prodsucts, 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.
