ABSTRACT:
An electrode wire for wire electric discharge machining includes a binary alloy of copper and zinc. The electrode wire is manufactured by hot-extruding an alloy including copper and zinc at a predetermined ratio and then cold-drawing and annealing the hot-extruded alloy, and α phase crystals and β′ phase crystals uniformly exist.
