Prodsuct Description


7079 aluminium alloy is a high strength, heat treatable wrought aluminium alloy used in the aircraft industry. Age-hardening heat treatment enhances the characteristics of AL 7079, eliminating variations in characteristics seen in Aluminium 7075. Aluminum 7079 has proven to be ideally suited for highly stressed parts and serves the aircraft industry.

Prodsuct Feature



Heat treatment of aluminum 7079

Solution treatment

Aging treatment

Annealing treatment


Machinability of Aluminum 7079

Alloy 7079 T-6 provides qualities comparable to alloy 7075-T6

F condition provides acceptable results

Improved machinability compared to fabricated and annealed tempers


Workability of Aluminum 7079

Can be formed similar to 7075

Form in “as-quenched” condition for best results

Annealing provides superior formability and a noticeable decline in workability following solution heat treatment



Applications of Aluminum 7079
