Specification for heat treatment of 6A02 aluminum plate products

(Summary description)6A02 aluminum plate products are widely used forged aluminum, with medium strength (lower than other forged aluminum), poor plasticity and machinability in annealed state, good plasticity and machinability after quenching and natural aging, and the same corrosion resistance as 2A21, 2A02 Good, it has the tendency of intergranular corrosion after artificial aging.

Information

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

Heat Treatment Specifications

Homogenization annealing: heating at 525 ~ 540 ℃; holding time for 12 ~ 14h; furnace cooling. 2) Rapid annealing: heating at 350~370℃; keeping heat for 30~120min depending on the effective thickness of the material; 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.

State: aluminum and aluminum alloy extruded bar (≤150mm, H112, T6 state)

The above are some related explanations about the heat treatment of 6A02 aluminum plate products, I hope to be helpful to everyone.
