摘要
A magnesium alloy that forms a stable protective film on the surface of molten metal, having excellent ignition resistance restricting natural ignition of a chip thereof as well as having excellent strength and ductility, so that the Mg alloy can be melted and cast in the air or a common inert atmosphere. The magnesium alloy includes, by weight, 7.0% or greater but less than 11% of Al, 0.05% to 2.0% of Ca, 0.05% to 2.0% of Y, greater than 0% but not greater than 6.0% of Zn, and the balance of Mg, and the other unavoidable impurities. The total content of the Ca and the Y is equal to or greater than 0.1 % but less than 2.5% of the total weight of the magnesium alloy.
