MAGNESIUM-BASED CASTING ALLOYS HAVING IMPROVED ELEVATED TEMPERATURE PERFORMANCE, OXIDATION-RESISTANT MAGNESIUM ALLOY MELTS, MAGNESIUM-BASED ALLOY CASTINGS PREPARED THEREFROM AND METHODS FOR PREPARING SAME

A magnesium-based casting alloy having improved elevated temperature properties and good salt-spray corrosion resistance. The inventive alloy comprises: 1 to 12% by wt. aluminum; 0.1 to 0.6% by wt. strontium; and 0.1 to 0.5% by wt. calcium, with the balance being magnesium except for impurities commonly found in magnesium alloys.

Magnesium-based casting alloys having improved elevated temperature properties

A magnesium-based casting alloy having good salt-spray corrosion resistance and improved creep resistance, tensile yield strength and bolt-load retention, particularly at elevated temperatures of at least 150&deg; C., is provided. The inventive alloy comprises, in weight percent, 2 to 9% aluminum and 0.5 to 7% strontium, with the balance being magnesium except for impurities commonly found in magnesium alloys.
