7075 aluminum plate is an Al-Zn-Mg-Cu series alloy, which can be heat-treated and strengthened. Among them, Zn and Mg mainly play the role of strengthening, and the role of Cu is mainly to improve the corrosion resistance of the alloy. 7075 aluminum plate is a superhard aluminum alloy with very good mechanical properties, 7075 aluminum alloy can achieve quite high strength under natural aging, and has low sensitivity to cracks. 7075 aluminum alloy has good processability, good corrosion resistance, and high strength can be obtained by age hardening. The tensile and shear strength can reach more than 600, and the elongation rate can reach as high as 70%. Click to Order
7075 Aluminum plate will not deform or warp after processing. All super-large and ultra-thick 7075 aluminum plates are ultrasonically detected to ensure no blisters and impurities. The thermal conductivity of 7075 aluminum plate is high, which can shorten the molding time and improve work efficiency. 7075 is a high-hardness, high-strength aluminum alloy, which is often used in the manufacture of aircraft structures, high-stress structural parts and mold manufacturing.
