7075 mainly contains zinc. It also belongs to the aviation series. It is an Al-Mg-Zn-Cu alloy, which is a heat treatable alloy and belongs to superhard aluminum alloy. It has good wear resistance. 7075 aluminum plate eliminates stress and will not deform or warp after processing. Ultra-large and ultra-thick 7075 aluminum plates are all tested by ultrasonic wave to ensure no sand holes and impurities. 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve the working efficiency. The main feature is that 7075 is an aluminum alloy with high hardness and strength, which is often used to manufacture aircraft structures and futures. It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance.
