Can you harden aluminum?
Aluminum alloys are subject to work hardening, also known as strain hardening.
To anneal a work hardened aluminum alloy, the metal must be heated to somewhere between 570°F to 770°F for a set amount of time, ranging from just thirty minutes to a full three hours..

How does 6061 aluminum relieve stress?
Usually for AA 6061 alloy, stress relieving is performed by re-heating the parts at 343°C for 1 h. This stress relieving is however accompanied by a considerable loss of material strength which subsequently reduces the functionality of the parts.
Can aluminum be annealed?
Annealing works fine for complicated and deep forming, but to form simpler stuff it’s unlikely that you’ll need it. Heat-treatable. This is one of the most common kinds of aluminum (especially 6061) and it anneals very well. You might need to anneal it a few times as you form it, since it’s prone to work hardening.
How do you heat treat 7075 aluminum?
HEAT TREATING 7075 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.
Can you heat treat aluminum?
Conclusion. While not all aluminum alloys benefit from heat treatment, we can heat-treat several alloys to increase the ease of forming or the strength of the finished product. Unlike steel or iron, aluminum requires rigid heat control to achieve optimal results, so special equipment is often required.
