6A02 has moderate strength, high plasticity under annealing and hot state, acceptable plasticity after quenching and natural aging, and its corrosion resistance in this state can be compared to 5A02.3A21. The alloy in artificial aging state has a tendency for intergranular corrosion, which can be cut and quenched, but not good after annealing. The alloy can be spot welded, hydrogen atom welded, or gas welded.
