  • Electrical contact means with gold-nickel alloy overlay
    Patent number: 4480014
    Abstract: Electrical contact tape having a base portion of nickel, copper or nickel-copper alloy and an overlay of metallic material on said base portion is improved by utilizing for such overlay a gold-nickel alloy of which the precentage by weight of nickel is in the range of from about 1.8% to 2.3%, the balance of the alloy being gold with or without one or more other metals other than nickel in trace amounts insufficient to produce precipitation thereof out of solution in the gold. Nibs of such tape are bonded to a leaf spring to form an electromechanical junction therewith, the gold-nickel alloy overlay of the nib being on its side away from the spring to provide an improved electrical contact surface for the spring contact assembly formed by such nib and spring.
