Definitions

  • the present invention comprises a combination 'of elements, methods of manufacture and the product thereof, brought out and exemplified in the disclosure hereinafter set forth, the scope of the invention being indicated in the appended claims.
  • the present invention comprises an improvement in silver-refractory metal contact elements and especially in contact elements formed of at least 6@%- silver.
  • silver is mixed with refractory metals taken from the tungsten-molybdenum group.
  • refractory metals taken from the tungsten-molybdenum group. These materials are usually prepared by mixing the powdered materials together, pressing the mixture and hot or cold worlnng the pressed product into suitable forms, from which contacts can be prepared.
  • Elements such as tin, zinc, cadmium, and copper will alloy with silver only but not with the refractory constituents, such as tungsten and molybdenum.
  • Metals such as cobalt and iron alloy with the molybdenum and tungsten, but not with the silver. For this reason they do not perform the same function as a metal such as man- Application January 5', 1939, Serial No. 249,476
  • the contacts covered by the present invention may be composed of the ingredients in approximately the following proportion.
  • An electric contact member composed of a refractory metal base and silver alloy containing 0.1 to 30% manganese.
  • An electric contact member formed of a bonded mass of refractory metal powders selected from the group consisting of tungsten and molybdenum impregnated with a silver alloy containing 0.1 to 30% manganese.
  • An electric contact element formed of 1 to 40% of a material selected from'the group consisting of tungsten and molybdenum, 0.1 to 30% manganese and the balance substantially all silver.
  • An electric contact element formed of l to 30% of a material selected from the group consisting of tungsten and molybdenum, 0.1 to manganese and the balance silver.
