The 7000 series aluminum sheet is the best series of eight aluminum alloy series, representing the highest level of current aluminum sheet production process. The most representative product of the 7000 series aluminum can be said 7075 aluminum sheet, which has high strength and high hardness. The main alloying elements of the 7000 series aluminum sheet are zinc and magnesium. As a cold forging alloy, the strength and hardness of the 7000 series aluminum sheet is much better than that of ordinary steel. In addition, the heat conductivity of the 7075 aluminium sheet is very good, and it can be used in some special industries to shorten the working time to a great extent and improve work efficiency.

7075 aluminum sheet

7075 aluminium sheet is a kind of Al-Zn-Mg-Cu super hard aluminum. 7075 aluminum alloy has been widely used in aircraft industry since the late 1940s. It is characterized by good plasticity after solution treatment, good heat treatment strengthening effect, high strength below 150 °C, and has particularly good low temperature strength; after other protection process, the ability of resist stress corrosion cracking can be improved. The 7075-T651 aluminum sheet is known as the most excellent product in 7075 aluminum alloy, it has higher strength than mild steel. 7075 aluminum alloy has good mechanical properties and anode reactions, so it is a typical aerospace aluminum alloy material. The performance of 7075 aluminum sheet is very superior, and it is free of trachoma and impurities after processing.
