Abstract
This invention aims to provide a recycled magnesium alloy having a good corrosion resistance and a process for producing the same. The process of the present invention comprises an adjusting step of adjusting composition of molten metal of a magnesium alloy so as to comprise, by mass: Al: 5 to 10%, Zn: not less than 1% and not less than three times of Cu content (%), Mn: 0.1 to 1.5% and the remainder: Mg and impurities with or without one or more reforming elements. While the upper limit of the Al content is restricted to a low level, the Zn content is increased in accordance with the Cu content. Therefore, the recycled magnesium alloy produced by this process can effectively suppress corrosion caused by Cu, which is one of corrosion-causing elements.
