7*** series is aluminum, zinc, magnesium alloy, one of the most powerful alloys for commercial use. 7075-T6 has good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 degrees, and particularly good low temperature strength, poor weldability, stress corrosion cracking tendency, Two-stage aging improves anti-scc performance.



Chemical composition: silicon si; 0.4 iron Fe; 0.5 copper CU; 1.2-2.0 manganese Mn; 0.3 magnesium Mg; 2.1-2.9 chromium Cr; 0.18-0.28 zinc Zn; 5.1-6.1 titanium Ti;
The main alloying element of 7075 T6 precision machining aluminum alloy plate for mold is zinc, which has high strength, good mechanical properties and anode reaction. It is mainly used in the manufacture of aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as upper and lower wing walls. Plate, purlin, etc.. Good solution after solution treatment, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low temperature strength, poor welding performance, stress corrosion cracking tendency. nt of 7075 T6 precision machining aluminum alloy plate for mold is also widely used in mold Processing, mechanical equipment, fixtures, etc.
