7000 series aluminum alloy belongs to the Al-Zn-Mg-Cu system of super-hard aluminum, and utilizes zinc as the principal alloying element. The combination of a smaller amount of magnesium allows it to be a heat-treatable alloy which offers very high strength. With the increase of zinc and magnesium content, the strength of the aluminum plate will be further improved. This series aluminum alloy has features of good mechanical properties, strong corrosion resistance and high low-temperature strength. Besides, 7000 aluminum alloys can be welded.
7000 series aluminum alloy is widely applied in aviation industry (aircraft frame, high-strength accessories), rocket components, screw propeller parts, etc.
7075 aluminum alloy is one of the highest strength aluminum alloys available. Its low density and high yield strength make the material ideally suited for applications such as highly stressed aircraft parts or parts subject to heavy wear.
