  • LEACH-RESISTANT LEADED COPPER ALLOYS
    Publication number: 20130192709
    Abstract: Copper alloys exhibiting enhanced oxidation resistance are provided by adding an amount of sulfur that is effective to enhance oxidative resistance. Such sulfur addition can be achieved by combining elemental forms of copper and sulfur and heating the mixture to form a molten alloy, or by forming a sulfur-rich pre-mix that is added to a base alloy composition. Forming a pre-mix provides improved homogeneity and distribution of the sulfur predominantly in the form of a metal sulfide.

  • SULFUR-RICH CORROSION-RESISTANT COPPER-ZINC ALLOY
    Publication number: 20130115128
    Abstract: Copper-zinc alloys exhibiting enhanced oxidation resistance are provided by adding an amount of sulfur that is effective to enhance oxidative resistance. Such sulfur addition can be achieved by forming a sulfur-rich pre-mix that is added to a base alloy composition. This technique provides improved homogeneity and distribution of the sulfur predominantly in the form of a metal sulfide.
