Aluminium zinc alloy
7079 aluminium alloy (UNS designation A97079) 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.

Heat treatment for aluminium 7079※
- Solution treatment
- Aging treatment
- Annealing treatment
Machinability※
- 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※
- Can be, formed similar to 7075
- Annealing provides superior formability and noticeable decline in workability following solution heat treatment
- Form in “as-quenched” condition for best results
Applications※
- Mobile industry equipment
- Aircraft parts, including wing panels and bulkhead assemblies
- Hydraulic units
- Highly stressed parts
