7075 aluminum is one of the strongest alloys commercially available. 7075 aluminum alloy has a compact structure and strong corrosion resistance, which is the best for aviation and marine plates. Normal corrosion resistance, good mechanical properties and anodic reaction. The fine grains provide better deep drilling performance and enhanced tool wear resistance.

Zinc is the main alloying element in 7075. Adding magnesium to the alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, so that the heat treatment effect of the alloy is far better than that of the aluminum-zinc binary alloy. Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength.
