Fabrication
Heat treatment of aluminium / aluminum 7079 includes solution treatment, aging treatment, and annealing treatment.
Machinability of aluminium / aluminum 7079 is good for T6 temper and matches the qualities of aluminium / aluminum 7075-T6.
Workability is similar to aluminium / aluminum 7075 alloy. Forming in as-quenched condition provides good results.
Annealing provides superior formability and obvious reduction in workability following solution heat treatment.
Applications
Aluminium / aluminum 7079 alloy is chiefly used in the following areas:
-
For highly stressed parts
-
In aircraft industry for aircraft parts such as wing panels and bulkhead assemblies
-
Mobile industry equipment
-
Hydraulic units
