  • Electric discharge machining electrode wire and manufacturing method therefor
    Patent number: 10399167
    Abstract: An electrical discharge machining electrode wire includes a core including a copper or a copper alloy, and a covering layer that covers a periphery of the core and includes a zinc. The covering layer includes an outermost layer consisting of an ?-phase of a copper-zinc based alloy. The outermost layer has a Cu concentration of 12 to 20 mass % and a variation range within 5 mass % in the Cu concentration in a longitudinal direction of the electrode wire.
    Type: Grant

  • Electrical discharge machining electrode wire and manufacturing method for same
    Patent number: 10307848
    Abstract: An electrical discharge machining electrode wire includes a core including a copper or a copper alloy, and a covering layer covering a periphery of the core and including a zinc. The covering layer includes an inner layer including a ?-phase of copper-zinc based alloy and covering the periphery of the core, and an outer layer including an ?-phase of copper-zinc based alloy and covering a periphery of the inner layer. An x-ray diffraction intensity of (0001) of the ?-phase is more than twice an x-ray diffraction intensity of (332) of the ?-phase.
