Magnesium alloy and method for making the same

Abstract

Magnesium-based alloys having good mechanical properties, such as mechanical strength, ductility, and castability, and methods of making the magnesium alloys are disclosed. The magnesium alloys comprise 8.7 to 11.8 wt % aluminum, 0.63 to 1.93 wt % zinc, 0.1 to 0.5 wt % manganese, 0.5 to 1.5 wt % rare earth elements, and a remainder of said magnesium alloy being composed of magnesium and unavoidable impurities.

What is claimed is: 
     
         1 . A magnesium alloy containing: 8.7 to 11.8 wt % aluminum, 0.63 to 1.93 wt % zinc, 0.1 to 0.5 wt % manganese, 0.5 to 1.5 wt % rare earth elements, and the rest being magnesium and unavoidable impurities. 
     
     
         2 . A magnesium alloy containing: 8.8 to 10.8 wt % aluminum, 0.63 to 1.02 wt % zinc, 0.1 to 0.5 wt % manganese, 0.51 to 1.23 wt % rare earth elements, and the rest being magnesium and unavoidable impurities.
