7003/7005/7020/7050/7075 T651/T851 High Hardness Aluminum Alloy Bar Aluminum Round Bar
The main alloy element of 7075 system aluminum alloy is zinc. Adding magnesium to the alloy containing 3% - 75% zinc can form mgzn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy much better than that of aluminum zinc binary alloy. If the content of zinc and magnesium in the alloy is increased, the tensile hardness will be further improved, but its resistance to stress corrosion and exfoliation corrosion will be reduced. After heat treatment, it can reach very high level The material of this series is made of 7075-7651 aluminum alloy, which is known as the best product in aluminum alloy. It has high strength and is far superior to mild steel. This alloy has good mechanical properties and anode reaction. It is mainly used in aerospace, mold processing, mechanical equipment, tooling and fixture, especially for aircraft manufacturing structure and other products with high strength and resistance High stress structure with strong corrosion resistance.
