The main alloying element of aluminum 7050 flat bar is zinc.Adding magnesium to the alloy containing 3% -75% zinc can form MgZn2 with significant strengthening effect, which makes the heat treatment effect of this alloy far exceed the aluminum-zinc binary alloy. The content of zinc and magnesium in the steel will further increase the tensile hardness, but its ability to resist stress corrosion and spalling corrosion will decrease. After heat treatment, it can achieve very high strength characteristics. Generally, this series of materials will be added A small amount of copper and chromium alloys. In this series, aluminum 7050 flat bar is used as the top grade, known as the best product in aluminum alloy, with high strength, far better than mild steel. This alloy has good mechanical properties and anode reaction. It is used in aerospace, mold processing, machinery and equipment. Tooling fixtures, especially for aircraft manufacturing structures and other high-stress structures that require high strength and strong corrosion resistance.
Aluminum 7050 flat bar is mainly used in the aerospace industry, blow molding (bottle) molds, ultrasonic plastic welding molds, high-end ball heads, shoe molds, paper molds, foaming molds, dewaxing molds, templates, fixtures, mechanical equipment, Mold processing. Used to make high-end aluminum alloy bicycle frames.
