The invention discloses a high-precision zinc-based alloy electrode wire, the composition in mass percentage of components of an external shell thereof being: Zn: 70.5-95%; Cu: 2.5-27%; X: 0.02-4.0%; Y: 0.002-0.4%, and unavoidable impurities introduced by raw material; where, X refers to any two metals selected from Ni, Ag, Cr, Si and Zr, and the content of each of these two metals is 0.01-2.0%; and Y refers to any two elements selected from Ti, Al, Co, B, and P, and the content of each of these two elements is 0.001-0.2%; the µ-phase in a structure of the external shell is above 80 wt%, the remainder being in ³-phase or ·-phase. The invention also provides a method for manufacturing the electrode wire. Compared with the prior art, the surface smoothness of metal workpieces cut by the electrode wire of the present invention is higher, and the surface quality is better, thereby improving the cutting precision. Moreover, the electrode wire manufacturing process of the present invention is simple, with high maneuverability and few steps, so as to facilitate large-scale and automated production. |
