A method for manufacturing an electrode wire 1 includes the steps of: firstly melting and mixing copper with a content of 60% by weight and zinc with a content of 40% by weight to form a copper/zinc binary alloy, and solidifying the copper/zinc binary alloy to form a full beta phase alloy 10. Further steps include galvanizing the full beta phase alloy, processing the full beta phase alloy by a low-temperature heat treatment, and prolonging the treating time of the low-temperature heat treatment to form a surface electric layer. The final step involves heat solidifying the surface electric layer to form a solid alloy layer 11 on the surface of the full beta phase alloy and to let the solid alloy layer form a gamma phase, an epsilon phase or an eta phase at different reaction temperatures. The electrode wire therefore only needs one working procedure. The electrode wire may be specifically for an electric discharge machine (EDM). |
