Abstract

See full text

The invention discloses a high-precision zinc-based alloy electrode wire, the external shell thereof consisting of: Zn: 70.5-95%; Cu: 2.5-27%; X: 0.02-4.0%; Y: 0.002-0.4%, and unavoidable impurities; where, X refers to any two kinds of metals selected from Ni, Ag, Cr, Si and Zr, and the weight percentage of each of these two kinds of metals is 0.01-2.0%; and Y refers to any two kinds of metals selected from Ti, Al, Co, B, and P, and the weight percentage of each of these two kinds of metals is 0.001-0.2%; the ε-phase in a metallurgical structure of the external shell is above 80 wt %. The invention also provides a method for manufacturing the electrode wire, which has high surface smoothness of the cut metal workpieces to improve the cutting precision. The method has simple process, high maneuverability, less steps, so as to facilitate large-scale and automated production.
