It is difficult to form magnesium alloys at room temperature due to its material properties. In this paper, I analyzed the optimal temperature conditions of the cold-forming using the high-pressure lamination test and the forming process was also was analyzed with the finite element analysis. That was quantitatively analyzed the mechanical properties through sheet metal test specimens at room temperature, 230℃, 250℃, 270℃ and 4 under the different conditions, depending on the method of forming the magnesium AZ31.
