Method of producing a light alloy product
 This invention relates to a method for producing a magnesium light alloy product. In order to enhance formability in plastically forming a magnesium alloy material and obtain high tensile strength and high proof stress in the final product, the magnesium alloy material is cast by using molten magnesium alloy containing strontium of 0.02 to 0.5 weight percent and then plastically formed into a magnesium light alloy product in set shape.
