6A02 aluminum bar is a widely used forged aluminum with medium strength (lower than other forged aluminum), poor plasticity and machinability in the annealed state, good plasticity and machinability after quenching and natural aging, and good corrosion resistance as 2A21 and 2A02 , After artificial aging, it has a tendency of intergranular corrosion. When the copper content of 6A02 aluminum bar is <0.1%, the corrosion resistance is high. 6A02 aluminum bar is easy to spot welding and hydrogen atom welding, and gas welding is still good. High plasticity in hot state, easy forging and stamping.
