This paper discribes press formability of magnesium alloy extrusions and rolled sheets at room temperature. AZ31,M1 extruded thin sheets and AZ31 rolled sheets are bended at various punch radius. The minimum punch radius at bending was evaluated, and it became clear that the formability of AZ31 extruded sheets are better than AZ31 rolled sheets. And it's minimum punch radius was about 2.5 times of sheet's thickness. But the AZ31 extruded sheets shows the large anisotropic mechanical properties for the orientation of extrusion directions. On the contrast, rolled sheets showed the isotropic mechanical properties.
