Hardness HB 10 -1 = 109 to 117 MPa

Heat treatment

Heat-treated and non-treated grades are produced. After annealing, excellent ductility is achieved and after aging, significant self-strengthening is achieved. Annealing. The alloy is heated to 500 °C, and upon cooling it acquires the flexibility of pure aluminum.
