PROBLEM TO BE SOLVED : To provide a magnesium cast alloy having excellent creep characteristics in a high-temperature range exceeding 150°C without containing Sr and RE which may cause many problems in the magnesium cast alloy containing Al, Ca, and Sn as main components, and a compressor impeller made therefrom. ŽSOLUTION : The magnesium cast alloy contains, by mass%, 3.0≤Al≤9.0, 2.5≤Ca≤7.0, and 1.6≤Sn≤5.0 and the balance being Mg and unavoidable impurities. A compressor impeller is obtained by casting the magnesium cast alloy into an impeller shape that has blades disposed around a hub spindle. ŽCOPYRIGHT : (C)2008, JPO&INPIT Ž |
