Abstract
According to the invention, the electrode wire (1) for electric discharge machining comprises a metal core (2), in one or more layers of metal or metal alloy. On the metal core (2), a coating (3) having an alloy different from that of the metal core (2) contains more than 50 wt % zinc. The coating (3) comprises copper-zinc alloy (3a) of fractured γ phase, and covers the majority of the metal core (2). The coating (3) contains covered pores (5a, 5b, 5c, 5d, 5) larger than 2 μm.
