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.
