Example Embodiment
[0018] Specific embodiment 1: The high-magnesium aluminum alloy cold drawn bar of this embodiment is composed of Mg: 9.2% to 10.4%, Mn: 0.5% to 0.7%, Ti: 0.05% to 0.10%, Fe: ≤0.3%, Si: ≤0.3%, Zn: ≤0.15%, Cu: ≤0.05%, Ni: ≤0.08% and the balance is made of smelting raw materials.
[0019] In this embodiment, the total amount of impurities in the high-magnesium aluminum alloy bar is ≤0.15%, and the impurities within this range have no effect on the performance of the high-magnesium aluminum alloy cold drawn bar.
Example Embodiment
[0020] Specific embodiment two: this embodiment is different from specific embodiment one in that the mass percentage of high magnesium aluminum alloy cold drawn bar is Mg: 9.5% to 10.2%, Mn: 0.55% to 0.65%, Ti: 0.06% to 0.09 %, Fe: 0.1%~0.25%, Si: 0.1%~0.25%, Zn: 0.06%~0.12%, Cu: 0.02%~0.04%, Ni: 0.04%~0.07% and the balance of Al to make.
Example Embodiment
[0021] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the mass percentages of high-magnesium aluminum alloy cold drawn bars are Mg: 9.9%, Mn: 0.6%, Ti: 0.08%, Fe: 0.2%, Si: 0.2%, Zn: 0.1%, Cu: 0.04%, Ni: 0.06%, and the balance is made of smelting raw materials.
