A wire electrode for a traveling wire EDM apparatus that comprises a copper clad steel core that is clad with a homogenous, outer brass layer using a classical bonding process. The copper clad steel core has a conductivity in the range of 50%-70% IACS (International Annealed Copper Standard) and the brass layer comprises 35%-50% by volume of the electrode. The brass layer comprises 65% copper and 35% zinc in an optimum construction. For a wire electrode having an overall diameter of 0.010 inches, the outer homogenous, brass layer is substantially 25 microns thick when the brass comprises 35% by volume of the wire and the copper clad steel core has a conductivity of 60% IACS and is contructed from AISI 10006 steel wire. |
