  • Publication number: 20020162607
    Abstract: A low creep electrical conducting aluminum cable wire alloy is provided. The wire alloy has about 0.07 to about 0.12 weight percent iron, about 0.04 to about 0.07 weight percent silicon, about 0.03 to about 0.08 weight percent zirconium, and a balance weight percent of aluminum.

  • Patent number: 4412580
    Abstract: Disclosed is an apparatus for and a method for more uniform and rapid cooling of molten metal, which is continuously cast into a wheel-band machine, by dispersing a relatively small amount of coolant from the periphery of a band presser wheel onto the continuous metal band at the point where the molten metal first contacts said band, with the unexpected beneficial effects of increasing the cast bar temperature and greatly reducing the amount of inverse segregation on the band-side surface of the resulting cast bar.

  • Patent number: 4177085
    Abstract: An improved method of continuously manufacturing a hot-formed, heat treatable aluminum base alloy product comprising casting a molten aluminum base alloy metal, cooling a cast metal during casting at a rate at which solidification shrinkage will not occur, hot-forming cast metal to form a rod at a temperature above the temperature level at which the alloy metals will precipitate to the grain boundaries of the aluminum base metal, heating the rod to a solutionizing temperature after hot forming and subsequently reducing the metal temperature from the solutionizing temperature of the metal to a temperature at which no substantial immediate precipitation occurs within a time interval before which any substantial precipitation occurs.

  • Patent number: 4028141
    Abstract: Disclosed in the appended specification and claims are a heat resistant aluminum alloy having a minimum conductivity of 61 percent IACS and high elongation, tensile strength and yield strength consisting of from about 0.04 to about 0.85 weight percent silicon, from about 0.30 to about 0.95 weight percent iron and from about 98.20 to about 99.66 weight percent aluminum and a method for producing said alloy comprising the steps of alloying the recited elements, continuously casting the alloy into a bar, hot-rolling the bar substantially as cast into a continuous rod, cold-drawing the continuous rod into a wire without intermediate anneals and annealing or partially annealing the wire.

  • Patent number: 3960606
    Abstract: Disclosed in the appended specification and claims are a heat resistant aluminum alloy having a minimum conductivity of 61 percent IACS and high elongation, tensile strength and yield strength consisting of from about 0.08 to about 1.00 weight percent silicon, no more than about 0.30 weight percent iron and from about 98.70 to about 99.92 weight percent aluminum and a method for producing said alloy comprising the steps of alloying the recited elements, continuously casting the alloy into a bar, hot-rolling the bar substantially as cast into a continuous rod, cold-drawing the continuous rod into a wire without intermediate anneals and annealing or partially annealing the wire.
