High speed extrudable non-flammability magnesium alloys and method for manufacturing magnesium alloy extrusion using the same

摘要

The present invention relates to a magnesium alloy having high strength and high ductility mechanical properties and excellent ignition resistance, more specifically, a stable protective film formed on the surface of a molten metal and capable of dissolving and casting in the atmosphere or in general inert atmosphere, The magnesium alloy according to the present invention contains 1.0 to 7.0% by weight of Al; and the magnesium alloy of the present invention has excellent strength and ductility at the same time. 0.05 to 0.3% by weight of Mn; 0.05 to 2.0% by weight of Ca; 0.05 to 1.0% by weight of at least one selected from the group consisting of Y, Gd, Sm, Nd, Dy and Er; Mg; And other unavoidable impurities.
