Abstract

A magnesium alloy material such as a magnesium alloy cast material or a magnesium alloy rolled material, excellent in mechanical characteristics and surface precision, a producing method capable of stably producing such material, a magnesium alloy formed article utilizing the rolled material, and a producing method therefor. The magnesium material producing method includes a melting step of melting a magnesium alloy in a melting furnace to obtain a molten metal, a transfer step of transferring the molten metal from the melting furnace to a molten metal reservoir, and a casting step of supplying a movable mold with the molten metal from the molten metal reservoir, through a pouring gate, and solidifying the molten metal to continuously produce a cast material. Parts are formed by a low-oxygen material having an oxygen content of 20 mass % or less. The cast material is given a thickness of from 0.1 to 10 mm.
