7075 aluminum sheet
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. Due to the fine grain structure inside 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, thick plate, heavy forging and golf components, precision parts and aircraft.
Properties of 7075 Aluminum Sheet
7075 aluminum sheet (Al-Zn-Mg-Cu) belongs to super-hard aluminum. As a kind of cold finished wrought alloy, it has great strength and hardness. It’s far better than mild steel. This alloy has good mechanical properties and anode reaction. 7075 aluminum sheet as a typical kind of aerospace aluminum alloy material is usually used for high-end fields.
Features of 7075 Aluminum Sheet
Alloy 7075 aluminum sheet have been and remain the baseline standard with a good balance of properties required for aerospace applications. 7075 aluminum sheet is among the highest strength alloys available and used in highly stressed parts. Corrosion resistance and machinability are rated as fair, though the addition of chromium provides good stress-corrosion cracking resistance in 7075 aluminum sheet products. As with alloy 2024, alloy 7075 is available in bare form or in clad ("Alclad") to offer even further protection from corrosion.
Applications of 7075 Aluminum Sheet
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.
