7A09

7075(American）

At present,7A09 aluminum alloy sheet round bar forgings

 is one of the most powerful domestic aluminum alloys, which can produce various specifications of plate, bar, profile, thick pipe fittings and forgings. There are four heat treatment states of T6, T73, T76 and T74. The chemical composition is better than that of 7A04 alloy, and its comprehensive properties are better. Under the condition of annealing or solid solution heat treatment, it has good forming properties at normal temperature. The forming performance is lower in the solid solution heat treatment and artificial aging condition, but with the increase of temperature, the forming properties are improved. Resistance welding can be carried out, and it is not suitable for welding.
