Abstract
In general, copper and graphite are frequently used as electrode materials for Electric Discharge Machining (EDM). Copper-tungsten alloy is used for special applications such as machining of cemented carbides and high-precision machining. Our company has been developed materials in order to improve the electric discharge machining property of copper-tungsten alloy. This paper introduces a new electrode, C-EDM, which has a better electric discharge machining property than that of conventional copper-tungsten alloys.
