Inventor: PARK SUNG HYUK
IPC: C22C23/06
Filed: 2020-03-30
Abstract: The present invention relates to a magnesium alloy for high-speed extrusion and a high-speed extrusion method using the same, wherein the magnesium alloy comprises: 3.0 - 7.0 wt% of bismuth (Bi); 1.0 - 5.0 wt% of aluminum (Al); remnants of magnesium (Mg); and unavoidable impurities. When an extruded material is produced by using the magnesium alloy for high-speed extrusion, a magnesium alloy having a sound surface without hot tears can be produced even under extrusion conditions of high temperature (an extrusion temperature of 300 - 450℃) and a high speed (an exit speed of 40 - 80 m/min). Therefore, the high-speed extrusion method in accordance with the present invention allows a user to produce an extruded material at a 10-fold or higher speed than high alloy-based common magnesium alloys such as AZ80 (Mg-8Al-0.5Zn), AZ91 (Mg-9Al-1Zn), ZK60 (Mg-6Zn-0.5Zr), and the like, thereby enhancing productivity and greatly reducing manufacturing costs, so that the high-speed extrusion method can be advantageously used to mass-produce an extruded material made of the magnesium alloy.
