  • Patent number: 6588934
    Abstract: The present invention relates to a copper base alloy suitable for use in bearing structures. The copper base alloy consists of from about 15 wt % to about 90 wt %, preferably from about 50 wt % to about 60 wt %, silver and the balance essentially copper. The copper base alloy is advantageously applied to a surface of a component used in the bearing structure such as a surface of a bushing.

  • Patent number: 4961905
    Abstract: A modified class of nickel aluminide (NiAl) type material is disclosed having useful amounts of toughness and ductility at low temperatures, e.g. room temperature. The basic NiAl material is modified with an additional of the material such as cobalt which produces a structure which is susceptible to undergoing a martensitic transformation. The martensitic structure when produced results in a significant increase in toughness and ductility at low temperatures.
