7075 Aluminium Alloy ( high strength high hardness)
7075 Aluminium Alloy ( high strength high hardness)
7075 Aluminium Alloy ( high strength high hardness)
The main alloying elements of 7075 Alloy are zinc, with high strength, good mechanical properties and anode reaction.
Mainly used in the manufacture of aircraft structure and other requirements of high strength, high stress structure corrosion resistance, such as aircraft, under the wing panel, stringer etc.
The solid solution treatment has good plasticity, good heat treatment strengthening effect, good strength and low temperature strength, poor welding performance and stress corrosion cracking tendency.
Also widely used in mold processing, mechanical equipment, tooling and fixtures, etc.
