7050 aluminum alloy has excellent strength, corrosion resistance and other properties. At the same time, it has very low density and is easy to process and manufacture. Therefore, it is often used in aerospace [1]. However, with the continuous progress of aerospace technology, especially in the case of particularly bad flight environment, the comprehensive performance requirements of aviation materials are particularly important. Therefore, 7050 aluminum alloy, which is widely used, is also facing more and more challenges. Researchers improve its microstructure through different processing methods, heat treatment processes and adding trace elements to further improve its comprehensive properties.

7050 t76511 extrusion aluminum bar extruded bars and sections require very good peripheral coarse-grained ring control.
7050 t76511 extrusion aluminum bar is mainly used to manufacture aircraft structures and other high stress structural parts requiring high strength and corrosion resistance, such as aircraft upper and lower wing wall panels, stringers, etc. it has good plasticity after solution treatment, good heat treatment strengthening effect, good strength below 150 ℃, especially good low temperature strength and poor welding performance, It has the tendency of stress corrosion cracking. It is also widely used in mold processing, mechanical equipment, tooling fixtures, aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf head, shoe mold, paper plastic mold, foam molding mold, dewaxing mold, mechanical equipment, and used to make high-end aluminum alloy bicycle frame.
