  • Patent number: 11545277
    Abstract: Bendability of a copper alloy wire is improved without decrease in an electrical conductivity of the copper alloy wire made of copper alloy containing zirconium. A cable includes: a two-core stranded wire formed by intertwining two electrical wires made of a conductor and an insulating layer covering the conductor; a filler formed around the two-core stranded wire; and a sheath formed around the filler and the electrical wire. The conductor is a copper alloy wire in which a precipitate containing the zirconium disperses, and has a crystal gain diameter that is equal to or smaller than 1 ?m, an electrical conductivity that is equal to or higher than 87% IACS, and a tensile stress that is equal to or larger than 545 MPa.

  • Patent number: 11476024
    Abstract: An insulated electric wire is composed of a conductor composed of a copper material, and an electrical insulating layer provided on an outer periphery of the conductor. For the constituent conductor of the insulated electric wire, in an orientation intensity ratio obtained by X-ray diffraction of a transverse cross section of the conductor, an intensity in a [200] crystal orientation is higher than an intensity in a [111] crystal orientation.

  • Publication number: 20220203433
    Abstract: A manufacturing efficiency of the wire rod made of the cast alloy including the additive element having the high activity to the oxygen is improved. An apparatus of manufacturing a wire rod includes: a tundish storing a molten metal; a mold for use in continuously casting the molten metal fed from the tundish; and an additive-element feeding unit continuously feeding an additive element (wire) to a feeding port of the mold.
