7079 aluminium 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

 * 1) Solution treatment
 * 2) Aging treatment
 * 3) Annealing treatment

Machinability

 * 1) Alloy 7079 T-6 provides qualities comparable to alloy 7075-T6
 * 2) -F condition provides acceptable results
 * 3) Improved machinability compared to fabricated and annealed tempers

Workability

 * 1) Can be formed similar to 7075
 * 2) Annealing provides superior formability and noticeable decline in workability following solution heat treatment
 * 3) Form in “as-quenched” condition for best results

Applications

 * 1) Mobile industry equipment
 * 2) Aircraft parts, including wing panels and bulkhead assemblies
 * 3) Hydraulic units
 * 4) Highly stressed parts
