  • COPPER ALLOY FOR HEAT EXCHANGER TUBE
    Publication number: 20160363397
    Abstract: An alloy comprising copper, nickel, tin and, optionally, phosphorus which can be used in, for example, a copper alloy tube for heat exchangers that provides excellent fracture strength and processability for reducing the weight of the tube and for use in high pressure applications with cooling media such as carbon dioxide.
    Type: Application

  • Process for high strength, high conductivity copper alloy of Cu-Ni-Si group
    Patent number: 7291232
    Abstract: A process for producing a copper-nickel-silicon alloy having a yield strength above 90 ksi with an electrical conductivity above 50% IACS. The process includes melting and continuously casting raw material to obtain an alloy containing 1-3 wt. % nickel, 0.2 to 0.7 wt. % silicon, remainder copper and unavoidable impurities; cold delivering the alloy to form a cold-rolled alloy, solution annealing the cold-rolled alloy; cold rolling the annealed alloy; and precipitation annealing the cold-rolled annealed alloy at a temperature of 450-500 degrees C. for four to ten hours with a cooling rate of 10-20 degrees C. per hour.
