7075 is one of the most powerful commercial alloys. Common corrosion resistance, good mechanical properties and anodic reaction.

Zinc is the main alloy element in 7075, adding magnesium to the alloy containing 3%-7.5% zinc can form a MgZn2 with remarkable strengthening effect, so that the heat treatment effect of the alloy is far more than the two element alloy of aluminum and zinc.
Increasing the content of zinc and magnesium in alloy, the tensile strength will be further improved, but its ability to resist stress corrosion and anti stripping corrosion will decrease.

The heat treatment can achieve very high strength characteristics. 7075 of the 7075 materials are generally added to a small amount of copper, chromium and other alloys, which are especially superior to the aluminum alloy in the system. It is known as the best product of aluminum alloy, which has high strength and far better than any soft steel.

The alloy has good mechanical and anodic reaction. The representative uses are Aeronautics and Astronautics, mold processing, mechanical equipment and fixture, especially for the manufacture of aircraft structures and other high stress structures requiring high strength and corrosion resistance.
