Magnesium alloy and method for making the same

Abstract

A magnesium alloy includes about 7.0 to about 8.0 wt % aluminum, about 0.45 wt % to about 0.90 wt % zinc, about 0.17 wt % to about 0.40 wt % manganese, about 0.50 wt % to about 1.5 wt % rare earth elements, about 0.00050 wt % to about 0.0015 wt % beryllium, and the rest being magnesium and unavoidable impurities. A method for making the magnesium alloy is also provided.

1 . A magnesium alloy containing: about 7.0 wt % to about 8.0 wt % aluminum, about 0.45 wt % to about 0.90 wt % zinc, about 0.17 wt % to about 0.40 wt % manganese, over 1.0 wt % to about 1.5 wt % rare earth elements, about 0.00050 wt % to about 0.0015 wt % beryllium, and the rest being magnesium and unavoidable impurities. 
     
     
         2 . The magnesium alloy of  claim 1 , wherein the rare earth element is selected from the group consisting of cerium, lanthanum, praseodymium, neodymium, yttrium, and combinations thereof. 
     
     
         3 . The magnesium alloy of  claim 2 , wherein the rare earth element is neodymium. 
     
     
         4 - 17 . (canceled) 
     
     
         18 . A magnesium alloy containing: about 7.0 wt % to about 8.0 wt % aluminum, about 0.45 wt % to about 0.90 wt % zinc, about 0.17 wt % to about 0.40 wt % manganese, about 0.5 wt % rare earth elements, about 0.00050 wt % to about 0.0015 wt % beryllium, and the rest being magnesium and unavoidable impurities. 
     
     
         19 . A magnesium alloy containing: about 7.0 wt % to about 8.0 wt % aluminum, about 0.45 wt % to about 0.90 wt % zinc, about 0.17 wt % to about 0.40 wt % manganese, about 0.8 wt % rare earth elements, about 0.00050 wt % to about 0.0015 wt % beryllium, and the rest being magnesium and unavoidable impurities.
