Descripción general del producto
Plato de aluminio 7075 is a high-strength aluminum-zinc (Al-Zn-Mg-Cu) alloy from the 7000 serie, one of the strongest aluminum alloys commercially available. With zinc and magnesium as principal alloying elements and copper for additional strength, 7075 achieves tensile strength comparable to many steels while weighing only one-third as much. It is solution heat treated and artificially aged to T6 or T651 temper for maximum strength. Nuestro 7075 aluminum plates are manufactured per ASTM B209, GB/T 3880, AMS 4045, and QQ-A-250/12, widely used in aerospace, defense, tooling, and high-performance structural applications.
