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