<p>A magnesium alloy 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 </= "b" </= 1.0, "a" and "c" satisfy a relationship, "c" </= "a" + 1.0; and when "b" is in a range, 1.0 </= "b" </= 3.0, "a," "b" and "c" satisfy a relationship, "c" </= "a" + "b" </= (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 DEG C at least. <IMAGE></p> |
