Abstract
An electrode wire, for electrical discharge machining, includes a metal core, and, on the metal core, a coating including one or more textured zones of copper-zinc alloy. Each of these textured zones is formed solely of an entanglement of copper-zinc gamma phase alloy and copper-zinc epsilon phase alloy. Inside each textured zone of copper-zinc alloy, the majority of the copper-zinc gamma phase alloy has a lamellar texture in which the spaces between the strips of copper-zinc gamma phase alloy are filled with the copper-zinc epsilon phase alloy.
Claims12
An electrode wire for electrical discharge machining, said electrode wire including:
- a metal core, and
- on the metal core a coating comprising one or more textured zones of copper-zinc alloy, each of said textured zones being formed exclusively by an entanglement of gamma phase copper-zinc alloy and epsilon phase copper-zinc alloy,
- wherein inside each textured zone of copper-zinc alloy the majority of the gamma phase copper-zinc alloy is in the form of a lamellar texture in which the interstices between the lamellae consisting of gamma phase copper-zinc alloy are filled by the epsilon phase copper-zinc alloy.
