Applications Aerospace, mold processing, mechanical equipment, fixtures, especially for the manufacture of aircraft structures and other high-stress structures requiring high strength, high corrosion resistance, etc.
7 series aluminium alloy Al-Zn-Mg-Cu alloy. 7 series aluminium alloy belongs to super-hard aluminium. It is a cold-treated forging alloy with high strength and strong corrosion resistance. It is the best for aviation and marine plates. Among the 7 series aluminium alloys, 7075-T651 aluminum alloy is especially top grade. It is known as the most excellent product in aluminium alloy, and has high strength and is far superior to any high-strength heat-treatable alloy of mild steel. Its characteristics are: good mechanical properties, good usability, easy processing and good wear resistance.
