7075 Aluminum Plate and Sheet belongs to Al-Zn-Mg-Cu superduralumin, which is a cold-treated alloy with high strength and hardness, far better than mild steel. Due to the fine grain size of 7075 aluminum alloy, it has excellent deep drilling performance, enhanced wear resistance of tools, good mechanical properties and anode reaction. At present, 7075 aluminum sheet is the preferred metal material under the requirement of lightweight conditions with lower density and higher hardness. It is one of the most potential alloys for commercial use. And It is widely used in the manufacturing of shoe mold, high-hardness mold, high-end mobile phone shell, golf components, precision parts and aircraft.

Features:

1. High Intensity. 7075 aluminum sheet is stronger than mild steel. After solution treatment, the plasticity is good, with high strength below 150℃ and excellent low temperature strength.
2. Strong Stress Corrosion. The stress corrosion performance of 7075 aluminum sheet is better than that of 7A04, especially in the temper of 7075-T651.
3. Good Heat Treatment Strengthening Effect. Zn is the main alloy element in 7075 aluminum sheet. Mg is added to the alloy containing 3%-7.5% Zn, so that the heat treatment strengthening effect of 7075 aluminum alloy is far better than that of Al-Zn binary alloy.

Application:

For the manufacture of aircraft structures and other high-stress structures with high strength and corrosion resistance, such as upper and lower wing panels, trusses and spacers. In addition, 7075 aluminum sheet is also used to make high-end mobile phone casings, precision components, golf components and other products. 7075 medium and heavy thickness aluminum plate is suitable for high hardness mold, shoe mold and high strength parts.
