How do you harden 7075 aluminum? - Keganhirl - 11-25-2021
7075 aluminum alloy may be solution annealed at 900°F for 2 hours at temperature, followed by a water quench. The alloy may then be given a precipation hardening (aging) heat treatment. Precipitation strengthening (aging) is done at 250°F for 24 hours and air cooled for T6.
