Abstract
An electrode wire includes a metal core that extends along a longitudinal axis. On the metal core is a coating including one or more zones of copper-zinc gamma phase alloy. Each of these zones is formed solely of a copper-zinc gamma phase alloy. The concentration of zinc, at an ambient temperature of 25° C., inside each of these copper-zinc gamma phase alloy zones is greater than 65.4 at. %. More than 50% of the copper-zinc gamma phase alloy zones are located at less than 1 μm from the outer face of the electrode wire.
Claims15
An electrode wire capable of being used as an electrode wire for electro-erosion machining, said electrode wire comprising:
- a metal core that extends along a longitudinal axis;
- and
- a coating on the metal core comprising one or more zones of copper-zinc gamma phase alloy, with each of these zones being solely formed by copper-zinc gamma phase alloy and the zinc concentration, at an ambient temperature of 25° C., inside each of these zones of copper-zinc gamma phase alloys being greater than 65.4 atomic %,
- wherein more than 50% of the zones of copper-zinc gamma phase alloy are located less than 1 μm from the outer face of the electrode wire.
