摘要： PROBLEM TO BE SOLVED: To provide a method for producing a recycled magnesium alloy having superior corrosion resistance. SOLUTION: The method for producing the recycled magnesium alloy includes an adjusting step of adjusting a composition of the molten metal of a magnesium alloy so as to include 5-10% Al, Zn in an amount of 1% or more and three times or more of Cu content (%), 0.1-1.5% Mn and the balance Mg. By increasing the Zn content according to the Cu content while controlling the upper limit of the Al content, the obtained recycled magnesium alloy effectively suppresses its corrosion originating in Cu which is one of corrosion-causing elements.
