Abstract
A wire electrode for electro-discharge machining made of a Cu alloy containing 38 to 50 percent by weight of Zn. The Cu alloy may also contain 0.01 to 1.0 percent by weight of Zr, 0.001 to 0.05 percent by weight in total of at least one element selected from a group of Ce, Ti, Mg, Bi and Mn, and/or 0.01 to 2.0 percent by weight of at least one element selected from a group of Al, Si, Fe, Ca and La. A method of manufacturing a wire electrode for electro-discharge machining, comprising the steps of preparing a Cu alloy material containing 38 to 50 percent by weight of Zn and thinning the Cu alloy material employing roll working and/or warm working at least in a part of working process.
