  • Patent number: 10478910
    Abstract: An electrode wire for electro-discharge machining includes a core wire including a first metal including copper and having one of phases ?, ?+??, and ??, a first alloy layer formed at a boundary region between the core wire and a second metal plated on an outer surface of the core wire due to mutual diffusion between the core wire and the second metal and having a phase ??, and a second alloy layer formed due to diffusion of the first metal to the second metal and having a phase ? and/a phase ?. A core wire material is erupted onto a surface of the electrode wire for electro-discharge machining, which includes the core wire, the first alloy layer, and the second alloy layer, along cracks appearing on the second alloy layer, so that a plurality of grains are formed on the surface of the electrode wire.

  • Patent number: 9156100
    Abstract: An electrode wire for electro-discharge machining and a method for manufacturing the same. The method includes preparing a wire rod, which includes a first metal and has a first diameter, as a core wire, plating a second metal on the core wire, performing a fine wire process for the core wire plated with the second metal so that the core wire has a second diameter, while forming a corrugation having a predetermined pattern on a surface of the core wire having a second diameter, and performing a heat treatment process to form a first alloy layer at a boundary surface between the core wire and the second metal through a mutual diffusion between the core wire and the second metal, and to form a second alloy layer at an outer portion of the first alloy layer through diffusion of the first metal toward the second metal.

  • Publication number: 20140339200
    Abstract: Disclosed are an electrode wire for electro-discharge machining and a method for manufacturing the same. The electrode wire includes a core wire including a first metal including copper, a first alloy layer formed at a boundary region between the core wire and a second metal plated on an outer surface of the core wire due to mutual diffusion between the core wire and the second metal, and a second alloy layer formed due to diffusion of the first metal to the second metal. A core wire material is erupted onto a surface of the electrode wire for electro-discharge machining, which includes the core wire, the first alloy layer, and the second alloy layer, along cracks appearing on the second alloy layer, so that a plurality of grains are formed on the surface of the electrode wire.
