Product Introduction


7022 aluminium alloy is an alloy in the wrought aluminium-zinc family (7000 or 7xxx series). It is one of the more complex grades in the 7000 series, with at least 87.85% aluminium by weight.

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[1] but worse than 7039 aluminium alloy. Good machinability, thermal conductivity and dimensional stability make 7022 alloy a material of choice for plastic injection molds.[2]

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.
