Aluminum Zinc Alloy

EN AW-7022

Available formats: Sheet metal, plates, bars, tubes and profiles.

Typical applications and uses

Aluminum Alloy Zinc EN AW 7022 is an alloy that was created to meet the demand of mold manufacturers for a material that could offer the hardness and work capacity necessary for the construction of molds and equipment.

 

Typical applications include molds for thermoplastic blowing and injection molding.

Heat treatments:

High strength alloy indicated for applications with structural load of sectors such as aerospace or defense. There is a risk of corrosion lowered tension.
