A magnesium alloy includes 0.1 to 6.0% by weight of Al, 0.25 to 6.0% by weight of Zn, 0.1 to 4.0% by weight of rare earth element (hereinafter referred to as "R.E."), and balance of Mg and inevitable impurities. Preferably, it includes 1.0 to 3.0% by weight of Al ("a"), 0.25 to 3.0% by weight of Zn ("b") and 0.5 to 4.0% by weight of R.E.: wherein when "b" is in a range, 0.25.ltoreq."b".ltoreq.1.0, "a" and "c" satisfy a relationship, "c".ltoreq."a"+1.0; and when "b" is in a range, 1.0.ltoreq."b".ltoreq.3.0, "a," "b" and "c" satisfy a relationship, "c".ltoreq."a"+"b".ltoreq.(1/2)"c"+4.0; in order to further improve creep properties at elevated temperatures while maintaining enhanced tensile strength at room temperature and up to 100.degree. C. at least.
