7A04 Aluminum Alloy Plate, Pipes, Tubes, Rods, Profiles and Fabrications

SaTraD Group – China’s Top leading steel, metal & raw material distributor.

7A04 Aluminum alloy commonly known as the Al-Zn-Mg-Cu series of ultra-high-strength aluminum alloys. The alloy has good wear resistance, good spot weldability, but poor in gas welding; It has good machinability after heat treatment, poor machinability after annealing.

Application

7A04 is mainly used to manufacture aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft lower wing panels, stringers, etc. After solution treatment, the plasticity is good, the heat treatment strengthening effect is good, it has good strength below 150 degrees, and has particularly good low temperature strength, poor welding performance, and stress corrosion cracking tendency. It is also widely used in mold processing, mechanical equipment, tooling and fixtures, aerospace industry, blow molding (bottle) molds, ultrasonic plastic welding molds, golf heads, shoe molds, paper molds, foam molding molds, dewaxing molds, machinery Equipment for making high-end aluminum alloy bicycle frames. It used for the first time as the body material of the smartphone OPPO.
