7005 aluminum sheet belongs to Al-Zn-Mg-Cu series super-hard aluminum. 7005 is one of the strongest commercial alloys. Good welding performance, heat treatment can be carried out to enhance strength
7075 aluminum sheet belongs to Al-Zn-Mg-Cu superduralumin, which is a cold-treated forging alloy with high strength and hardness, far better than soft steel.
7050 aluminum sheet is a high-strength heat-treatable alloy. It is based on 7075 aluminum alloy, which increases the Zn, Cu content and Cu / Mg ratio to increase the strength, and replaces Cr with Zr to overcome the quenching sensitivity problem and inhibit re-crystallization.
