Abstract
The present invention is to provide a magnesium alloy comprising 0.001 parts by weight to 1.0 parts by weight of scandium and the balance of magnesium and unavoidable impurities, based on 100 parts by weight of a magnesium alloy, wherein the magnesium alloy has increased Fe solubility and reduced corrosion while providing excellent mechanical properties and corrosion resistance, and a method for producing the same. The magnesium alloy of the present invention can improve the corrosion resistance of the magnesium alloy by using scandium which can simultaneously prevent from microgalvanic corrosion between a substrate and impurities without deteriorating mechanical properties and improve the passivation property of the coating formed on the surface.
