6A02 aluminum alloy

1. Introduction: Aluminum plate is a widely used forged aluminum with medium strength (lower than other forged aluminum). In the annealed state, the plasticity and machinability are poor. After quenching and natural aging, the plasticity and machinability are good. The corrosion resistance is as good as , there is a tendency for intergranular corrosion after artificial aging. When the copper content of the aluminum plate is <., the corrosion resistance is high. Aluminum plates are easy to spot weld and hydrogen atomic weld, and gas welding is good. It has high plasticity in hot state and is easy to forge and stamp.
