  • WHITE-COLORED COPPER ALLOY WITH REDUCED NICKEL CONTENT
    Publication number: 20140308159
    Abstract: Disclosed is a white-colored copper alloy comprising by weight up to 30% zinc, up to 20% manganese, up to 5% nickel with the balance copper. This alloy may have from 6% to 25% zinc, from 4% to 17% manganese, from 0.1% to 3.5% nickel and the balance copper. The balance copper in the alloy may further contain at least one of: up to 0.5% of at least one of the group which consists of Sn, Si, Co, Ti, Cr, Fe, Mg, Zr, and Ag; and up to 0.1% of at least one of the group which consists of P, B, Ca, Ge, Se, Te. It may also contain up to 0.3% Zr by weight. The alloy may have an electrical conductivity greater than 2.5% IACS at eddy current gauge exciting frequencies between 60 kHz and 480 kHz.

  • METHODS OF MAINTAINING AND USING A HIGH CONCENTRATION OF DISSOLVED COPPER ON THE SURFACE OF A USEFUL ARTICLE
    Publication number: 20140230510
    Abstract: A method for maintaining and using a high concentration of dissolved copper on a surface of a useful article by providing a copper surface without coatings thereon, which increase the wetting angle and which isolate the copper surface and which has a surface roughness between 2 and 50 micro inches Ra, so as to kill microbes thereon.
    Type: Application
