Document Type and Number:
WIPO Patent Application WO/2021/155648
Kind Code:
A1
Abstract:
A 6-series aluminum alloy, containing 0.7 wt%-1.1 wt% of magnesium, 0.5 wt%-1.1 wt% of silicon, 0.5 wt%-1.0 wt% of copper, greater than 0 and less than or equal to 0.15 wt% of manganese, greater than 0 and less than or equal to 0.1 wt% of iron, greater than 0 and less than or equal to 0.1 wt% of chromium, greater than 0 and less than or equal to 0.05 wt% of titanium, less than or equal to 0.05 wt% of zinc, and the balance aluminum, wherein the total mass fraction of Mn, Cr and Ti is 0.02 wt%-0.25 wt%, and the total mass fraction of Mn and Fe is 0.02 wt%-0.2 wt%. The aluminum alloy has excellent mechanical properties such as tensile strength and yield strength, and has the characteristics such as good plasticity, strong corrosion resistance, and good welding machinability.
