  • Nickel-based electrical contact
    Patent number: 4732821
    Abstract: Nickel material comprising controlled amounts of hydrogen has low electrical contact resistance even after prolonged exposure to an oxidizing ambient. When used as a surface layer on an electrically conducting member, such material is suitable as a contact material and represents an inexpensive alternative to gold. And, when prepared in the form of microscopic flakes, such material is suitable for use in electrically conductive inks and adhesives.
