Abstract: A copper alloy that is devoid of beryllium and has a 0.2% offset yield strength of at least 70 ksi and an electrical conductivity of at least 75% IACS is disclosed. The copper alloy comprises chromium, silicon, silver, titanium, zirconium, and balance copper. The alloy is prepared by cold working, solution annealing, and aging. The alloy can be used in several different applications.

Abstract: A copper alloy that does not contain beryllium and has a 0.2% offset yield strength of at least 80 ksi and an electrical conductivity of at least 48% IACS is disclosed. The copper alloy contains nickel, silicon, chromium, manganese, zirconium, and balance copper. The alloy is prepared by cold working, solution annealing, and aging. The alloy can be used for example, as a heat sink.

Abstract: The present disclosure relates to powders and wires made from a copper-containing alloy. The copper-containing alloy is a copper-nickel-tin alloy or a copper-nickel-silicon-chromium alloy. Articles formed from the metal powder exhibit high thermal conductivity, high wear resistance, and thermal stability. The powders and wire also be used as a feed material for thermal spraying and copper-containing coatings are disclosed. The copper-containing alloy material promotes increased life of engine components and fuel efficiency when used as a cylindrical liner in an internal combustion engine.

Abstract: Disclosed herein are nickel beryllium alloys having improved corrosion and hardness characteristics relative to known nickel beryllium alloys. The alloys have a chemical composition with about 1.5% to 5% beryllium (Be) by weight, about 0.5% to 7% niobium (Nb) by weight; and nickel (Ni). Up to about 5 wt % chromium (Cr) may also be included. The alloys display improved hardness and corrosion resistance properties.

Abstract: A sliding bearing includes a relatively soft first metallic material incorporated into a matrix of a relatively harder second metallic material. The first material is soluble in the second material. Particles of the first material are coated with a protective barrier coating to protect the first material from dissolving in the second material during processing and thereby yielding discrete secondary phases of the first material within the matrix of the second material. The first material may comprise tin or bismuth coated with a barrier coating of nickel within a copper-tin matrix of second material.
