Abstract

See full text

Disclosed are an electrode wire for electro-discharge machining and a method for manufacturing the same. The electrode wire includes a core wire including a first metal including copper, a first alloy layer formed at a boundary region between the core wire and a second metal plated on an outer surface of the core wire due to mutual diffusion between the core wire and the second metal, and a second alloy layer formed due to diffusion of the first metal to the second metal. A core wire material is erupted onto a surface of the electrode wire for electro-discharge machining, which includes the core wire, the first alloy layer, and the second alloy layer, along cracks appearing on the second alloy layer, so that a plurality of grains are formed on the surface of the electrode wire.
