Abstract
The feasibility and application of the cold drawing of magnesium alloy wires and tubes were examined by Finite Element Method (FEM) and experiments. Magnesium alloy, which is light and has high heat-radiating ability, has been attracting attention for applications, such as the body of computers, medical instruments and mobile phones. However, cold plastic working of the alloy is very difficult, so generally hot working is necessary. In this study, a technique for obtaining fine wires and tubes with high strength, quality and surface morphology by cold drawing was examined, while decreasing production cost. In addition, the shearing strain of magnesium alloy wires and tubes drawn under various drawing conditions was calculated by FEM analysis. It was clarified that cold drawing of magnesium alloy is possible.
