2017 aluminum alloy china
1.Overview: 2017's alloying element is copper, it is the first 2-series alloy to gain industrial application, it has high strength and good cutting and machining performance, but the corrosion resistance is poor.
2.Application: 2017 is mainly used in rivets, general mechanical parts, aircraft, ships, transportation, building structural parts, transportation vehicle structural parts propeller elements and accessories.
3.2017 Chemical composition (mass fraction %): iron (Fe) 0.7 manganese (Mn) 0.40 ~ 1.0 magnesium (Mg) 0.4 ~ 0.8 silicon (Si) 0.2 ~ 0.8 zinc (Zn) 0.25 titanium (Ti) 0.15 chromium (Cr) 0.1 (Cu) 3.5 ~ 4.5 aluminum (Al) remainder of the 3.2017 Aluminum alloy by solid solution treatment, and refrigerated, after taking out the Ageing 1.5h, can reach the shear strength value of the material.
