Abstract
The present invention relates to a magnesium alloy material and a method for manufacturing the same. The magnesium alloy material comprises, with respect to the total of 100 wt % thereof: Sc of 0.01 to 0.3 wt %; Al of 0.05 to 15.0 wt %; and the balance being Mg and other unavoidable impurities, wherein the magnesium alloy comprises a secondary phase compound comprising Al and Sc in the alloy in which a Volta potential difference between the secondary phase compound and a magnesium base is less than 920 mV.
