An electrode wire for discharging working; the electrode wire being formed by an alloy of copper and zinc; in manufacturing process, passing the alloy with a form of fluid through a furnace so as to form with a desire shape; wherein by siphon theory, a metal tube serves to suck the alloy; the process is made continuously in a predetermined temperature; then the alloy being performed with cold-extension and annealing repeatedly so as to form with electrode wire which is stable, uniform and has a preferred electric conductivity. in the alloy of copper and zinc, the content of zinc is about 35˜45%. An extension strength of the wire is between 650 to 1150 MPa.
