PURPOSE:To achieve a wire electrode having excellent machining speed and low adhesion by employing alloy composed of Cu, Zn, Al and Si as the wire electrode material. CONSTITUTION:An alloy containing Zn: 26-38wt%, Al: 0.2-1.5wt%, Si: 0.2- 1.0wt% and impurities inevitable with Cu is employed as the wire electrode material for wire-cut electric discharge machining. When adding one or more than two kinds of Mn, Sn, Mg, Zr by 0.2-1.0wt%, the machining speed and adhesion to the workpiece can be improved. |
