(57) Abstract: Al is 5 to 16% by weight and Zn is 0.5 to 10%. % By weight, 0.1 to 1% by weight of Mn and 0.005 to Ti. In a method of smelting and casting a magnesium alloy melt having a composition containing 0.1% by weight and 0.001 to 0.02% by weight of B, and the balance being Mg and unavoidable impurities, Mn is easily added during the smelting. A magnesium alloy for a galvanic anode, which can be added to a magnesium alloy and can be produced by casting the molten magnesium alloy to produce a large amount of electricity, that is, a highly efficient and long-life magnesium alloy. Provide a way. SOLUTION: When melting a magnesium alloy melt, Z An n-Mn alloy is used as a raw material for melting Mn. |
