This paper describes the influence of the Al,Zn and Mn contents on extrudability of magnesium alloy. As Al and Zn content increase,extrusion speed limit becomes smaller because of the surface cracks. And it became clear that extrusion pressure of the magnesium alloys are not so higher than 6063 aluminum alloy. The influence of Al, Zn and Mn contents on extrusion pressure has evaluated as experimental equation.
