Audited Supplier 7050 aluminum is a 7000-series aluminum alloy: the main alloying addition is zinc and it is formulated for primary forming into wrought products. 7050 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-7050. AlZn6CuMgZr is the EN chemical designation. Additionally, the UNS number is A97050.
It originally received its standard designation in 1971.
The properties of 7050 aluminum include six common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 7050 aluminum to: 7000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Aluminium / Aluminum 7050 alloy can be formed in O temper or heat treated conditions.
Aluminium / Aluminum 7050 alloy should not be welded in order to prevent cracking and development of porosity. The weld joint produced will be weaker than the parent metal. Gas tungsten or gas metal arc welding methods are not preferred for welding this alloy.
Aluminium / Aluminum 7050 alloy can be heat treated at 477°C (890°F). The time taken for this process is based upon the thickness of the section.
Aluminium / Aluminum 7050 alloy can be cold worked using conventional methods.
Aluminium / Aluminum 7050 alloy is aged using two-stage heat treatment. It is heated at 122°C (250°F) for 3 to 6 h. It is again heated at 163°C (325°F) for 15 h followed by cooling in air.
Aluminium / Aluminum 7050 alloy can be hardened by precipitation heat treatment.
