Abstract
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.
