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.
Chemical composition
Heat treatment for aluminium 7079
- Solution treatment
- Aging treatment
- Annealing treatment
Machinability
- Alloy-temper 7079-T6 provides qualities comparable to alloy-temper 7075-T6
- -F temper 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 âÂÂas-quenchedâ -W temper condition for best results
Applications
- Mobile industry equipment
- Aircraft parts, including wing panels and bulkhead assemblies
- Hydraulic units
- Highly stressed parts
