Like most other highly alloyed alloys, 7022 is a high strength alloy, with yield strength of 370 MPa. Designed to be resistant to stress corrosion cracking, it has decent corrosion and oxidation resistance comparable to 7075 aluminium alloy but worse than 7039 aluminium alloy. Good machinability, thermal conductivity and dimensional stability make 7022 alloy a material of choice for plastic injection molds.
7022 alloy can be heat treated to increase tensile strength in expense of workability, with most common grade been T651.
Notes: Alternative names for 7022 alloy are A7022 and AA7022.
