  • GRAIN REFINED TIN BRASS
    Publication number: 20010001400
    Abstract: There is provided a tin brass alloy having a grain structure that is refined by the addition of controlled amounts of both zinc and iron.
    Type: Application
    Filed: June 30, 1997
    Publication date: May 24, 2001
    Applicant: Dennis R. Brauer et al
    Inventors: DENNIS R. BRAUER, JOHN F. BREEDIS, RONALD N. CARON, CARL DEPPISCH
  • Iron modified tin brass
    Patent number: 6132528
    Abstract: There is provided a tin brass alloy having a grain structure that is refined by the addition of controlled amounts of both zinc and iron. Direct chill cast alloys containing from 1% to 4%, by weight of tin, from 0.8% to 4% of iron, from an amount effective to enhance iron initiated grain refinement to 35% of zinc and the remainder copper and inevitable impurities are readily hot worked. The zinc addition further increases the strength of the alloy and improves the bend formability in the "good way", perpendicular to the longitudinal axis of a rolled strip. Certain of the grain refined brass alloys are useful as semisolid forming feedstock.
    Type: Grant
    Filed: June 23, 1998

  • Iron modified tin brass
    Patent number: 5853505
    Abstract: There is provided a tin brass alloy having a grain structure that is refined by the addition of controlled amounts of both zinc and iron. Direct chill cast alloys containing from 1% to 4%, by weight of tin, from 0.8% to 4% of iron, from an amount effective to enhance iron initiated grain refinement to 20% of zinc and the remainder copper and inevitable impurities are readily hot worked. The zinc addition further increases the strength of the alloy and improves the bend formability in the "good way", perpendicular to the longitudinal axis of a rolled strip.
