Abstract

The invention provides a magnesium alloy material of high intensity and high yield ratio. The alloy comprises the following components by mass: 5.0-9.0% of Zn; 0.5-1.5% of Mn; 1-10% of Sn; less than 0.15% of inevitable impurities; and the balance magnesium. By means of plastic forming and a choice of reasonable technological conditions for heat treatment after forming, the magnesium alloy material of the invention can be of high intensity and high yield ratio, and is higher than the high-strength wrought magnesium alloy ZK60 in terms of yield strength and tensile strength. With low cost, good extrudability and formability at a low temperature, the magnesium alloy material provided in the invention boasts substantial application potential, thus being able to partly replace the magnesium alloy material ZK60.
