  • Publication number: 20110287279
    Abstract: A porous metal member composed of an alloy at least containing nickel and tungsten is provided. The alloy may contain 50 to 80 wt % of nickel and 20 to 50 wt % of tungsten and may further contain 10 wt % or less of phosphorus and/or 10 wt % or less of boron. Such a porous metal member can be produced by, for example, making a porous base such as a urethane foam be electrically conductive, forming an alloy film containing nickel and tungsten, then removing the porous base from the alloy film, and subsequently reducing the alloy.

  • Publication number: 20110036614
    Abstract: An aluminum electric wire includes an annealing conductor that is made up of elemental wires made of an aluminum alloy containing 0.90-1.20 mass % Fe, 0.10-0.25 mass % Mg, 0.01-0.05 mass % Ti, 0.0005-0.0025 mass % B, and the balance being Al and has a tensile strength of 110 MPa or more, a breaking elongation of 15% or more, and an electric conductivity of 58% IACS or more, and an insulating material covering the conductor. The wire is produced by casting an aluminum alloy prepared by rapidly solidifying a molten aluminum alloy having the above composition, producing the wires by subjecting the alloy to plasticity processing, producing the conductor by bunching the wires, subjecting the wires or the conductor to annealing at 250° C. or higher, and then covering the conductor with the insulator.
