7075 aluminum alloy is a kind of cold forging alloy, high strength, far better than mild. 7075 is one of the most powerful commercial alloy. General corrosion resistance, good mechanical properties and the anodic reaction. Small grain that better deep drilling performance, tool wear resistance increased, thread rolling more out of the ordinary. The aerospace industry (bottle), blow molding mold, ultrasonic plastic welding mold, golf head, shoes, paper mould, foaming molding, lost-wax mold, template, fixtures, machinery and equipment, mold processing, used in the production of high-end aluminum alloy bicycle frame.
