H12 H14 H16 H18 Temper 1145 Aluminium Alloy With Strong Electric Properties
Product introduction of 1145 Aluminum Sheet:
Aluminium / Aluminum 1145 alloy is a difficult alloy to machine. It is slightly easier to machine in the H16, 18 or 19 tempers than in the softer or annealed temper form.

Aluminium / Aluminum 1145 alloy is a non-heat treatable alloy that can be hardened by cold working.
Aluminium / Aluminum 1145 alloy is extremely easy to cold work in the softer tempers such as annealed, H12, 14, 16 tempers. It is a lot more difficult with harder tempers but it is still possible.
Annealing can be performed at 343°C (650°F) for a suitable amount of time and then air cooled.
Aluminium / Aluminum 1145 alloy can be hardened by cold working only.
