The magnesium alloy and magnesium die-cast product null aluminum

摘要

PROBLEM TO BE SOLVED: To provide a die casting magnesium alloy capable of improving the high-temperature creep characteristics without causing reduction of room temperature strength and a magnesium die casting including the same.;SOLUTION: To an AZ91 alloy comprising, by weight, 6.0 to 11.0% aluminum, 0.1 to 2.5% zinc and 0.1 to 0.5% manganese, at least one kind selected from 0.1 to 2.0% silicon, 0.1 to 1.2% rare earth and 0.2 to 0.8% zirconium is added, so as to be an AZ91 based alloy, and, to the alloy, at least either 0 to 1.5% antimony or 0.2 to 3.5% calcium and 0.1 to 1.5% strontium are added, and the balance being inevitable components. The magnesium die casting is produced by the use of the alloy.;COPYRIGHT: (C)2006,JPO&NCIPI
