Aluminum Zinc Alloy

EN AW-7075

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

Typical applications and uses

Aluminum Alloy Zinc EN AW 7075 is the alloy with the highest characteristics in aluminum. The development of this alloy has made its use possible in fields previously reserved for steels.

 

7075 zinc alloy aluminum, is applied in armament, automobile industry, screws, ski poles, fishing rods, arrows, blow molds, stamped parts for mountaineering, etc.
