Cast Aluminum Tooling Plate

7075 is an aluminum alloy, with zinc as the primary alloying element. It is one of the strongest aluminum alloys comparable to many steels, and has good fatigue strength and average machinability. 7075 was specifically designed for aircraft frames because of its strength somewhat greater than steel while maintaining the light weight of aluminum.

Aluminum alloy 7050 has high strength at subzero temperatures. However, their strength can be reduced at high temperatures. 7050 is heat treatable so as to produce mechanical properties of high strength and toughness. It has very good resistance to stress corrosion cracking. Commonly used in the manufacture of aircraft and other structures.
