What is aluminum plate 7075Posted by xuanxuan geng on May 17th, 2022 7075 aluminum plate has high hardness, and many molds with high strength requirements are not ideal under the application conditions of 6061 aluminum plate. The service life of the mold can be increased on the 7075 aluminum plate, which is also the best embodiment of the characteristics of 7075. 7075 aluminum plate has high strength, ordinary corrosion resistance, good mechanical properties and anodic reactivity, and belongs to Al-Zn-Mg-Cu series super-hard aluminum. The alloy is an ultra-high-strength deformed aluminum alloy that has been used in the aircraft manufacturing industry in the late 1940s and is still widely used in the aviation industry. Its characteristics are good plasticity after solution treatment, good heat treatment strengthening effect, high strength below 150 ?, especially good low temperature strength; poor welding performance; stress corrosion cracking tendency; it needs to be covered with aluminum or other protective treatments. Dual-stage aging can improve the alloy\'s resistance to stress corrosion cracking. The plasticity in the annealed and just-quenched state is slightly lower than that of the homomorphic 2A12, and slightly better than that of 7A04. The static fatigue of the sheet, the gap sensitivity, and the stress corrosion performance are better than that of 7A04. Aluminum plate 7075 is mainly used in: aerospace industry, blow mold, ultrasonic plastic welding mold, shoe mold, paper mold, foam molding mold, wax mold, template, fixture, machinery, mold processing.
