Information

6A02 aluminum plate is widely used forged aluminum, medium strength (lower than other forged aluminum), plasticity and poor machinability in annealed state, good plasticity and machinability after quenching and natural aging, corrosion resistance is as good as 2A21, 2A02 , After artificial aging, there is a tendency of intergranular corrosion. When the copper content of 6A02 aluminum plate is less than 0.1%, the corrosion resistance is high.

6A02 aluminum plate
6A02 aluminum plate is widely used forged aluminum, medium strength (lower than other forged aluminum), plasticity and poor machinability in annealed state, good plasticity and machinability after quenching and natural aging, corrosion resistance is as good as 2A21, 2A02 , After artificial aging, there is a tendency of intergranular corrosion. When the copper content of 6A02 aluminum plate is less than 0.1%, the corrosion resistance is high. 6A02 aluminum plate is easy to spot welding and hydrogen atom welding, and gas welding is good. The plasticity is very high in the hot state, and it is easy to forge and stamp.
6A02 aluminum plate mechanical properties:
Tensile strength σb (MPa): ≥295
Elongation δ5 (%): ≥12
6A02 Aluminum plate heat treatment specification:
1) Homogenization annealing: heating 525~540℃; holding time 12~14h; furnace cooling. 2) Rapid annealing: heating 350~370℃; depending on the effective thickness of the material, heat preservation 30~120min; air cooling. 3) Quenching and aging: quenching at 510~530℃, water cooling; artificial aging at 150~165℃, 6~15h, air cooling; natural aging at room temperature 96h.
