7075 aluminium 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. Due to the fine grain structure inside 7075 aluminium alloy, it has excellent deep drilling performance, enhanced wear resistance of tools, good mechanical properties and anode reaction. At present, 7075 aluminium sheet/plate is the preferred metal material under the requirement of lightweight conditions with lower density and higher hardness. It is one of the most selling and potential alloys for commercial use. Its main tempers are T6 and T651.

Applications and 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 shee is better than that of 7A04, especially in the temper of 7075-t651.

3. Good Heat Treatment Strengthenin Effect. Zn is the main alloy element in 7075 aluminium sheet. Mg is added to the alloy containing 3%-7.5% Zn, so that the heat treatment strengthening effect of 7075 aluminium alloy is far better than that of Al-Zn binary alloy.

4. Other features. The plasticity under annealing and hardening conditions is slightly lower than 2A12 in the same state, but slightly better than 7A04, etc.

The Use of 7075 Aluminium Sheet/Plate

7075 Aluminium Sheet Uses

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.
