Quick Details

7075 aluminum alloy is a cold treatment forging alloy with high strength, far better than soft steel. 7075 is one of the commercially powerful alloys. 7075 aluminum alloy has a tight structure and strong corrosion resistance, for aviation and marine plates. Ordinary corrosion resistance, good mechanical properties and anodic reaction. Fine grains make the depth drilling performance better, tool wear resistance enhanced, thread rolling more distinctive.

7075 aluminum plate is Al-Zn-Mg-Cu system super hard aluminum, 7075 alloy is the end of the 1940s has been used in the aircraft manufacturing industry, still in the aviation industry is widely used in ultra-high strength deformed aluminum alloy.

The main uses of 7075 aluminum plate: aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding molds, high children's ball head, shoe mold, paper-plastic mold, foam molding mold, waxing mold, paradigm, fixture, mechanical equipment, mold processing.   
 
7075 aluminum plate features.
 
1. High strength heat treatable alloy.   
 
2. Good mechanical properties.   
 
3. Good usability.   
 
4. Easy to process, good wear resistance.   
 
5.Good corrosion resistance and oxidation resistance.   

7075 aluminum sheet chemical composition: zinc is the main alloying element in 7075, to the alloy containing 3%-7.5% zinc added magnesium, can form a significant strengthening effect MgZn2, so that the heat treatment effect of the alloy is better than aluminum - zinc binary alloy. By increasing the zinc and magnesium content of the alloy, the tensile strength will be further improved, but its resistance to stress corrosion and spelling corrosion will then be reduced. Subjected to heat treatment, it can reach very high strength characteristics. 7075 materials are generally added to a small amount of copper, chromium and other alloys, the system among the A7075-aluminum alloy is particularly good, known as the excellent products in aluminum alloy, high strength.
