    摘要： 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. Other metallic elements that undergo peritectic decomposition in a tin brass alloy, such as cobalt, iridium, niobium, vanadium and molybdenum may substitute for from a portion to all of the 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.

    摘要： There is disclosed a machinable alpha beta brass having reduced lead content. The alloy contains bismuth to improve machinability. Either a portion of the zinc is replaced with aluminum silicon or tin, or a portion of the copper is replaced with iron, nickel or manganese. The amount of zinc and, in some embodiments zinc substitute, is that effective to provide a sufficient amount of the beta phase to enable hot working at temperatures above 600 °C. Figures 2 through 4 illustrate composition regimes of the invention in correspondence with elements substituting for zinc.

    摘要： 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.

    摘要： An alpha brass (copper/zinc alloy with less than 39 %, by weight, of zinc) stock alloy has controlled additions of nickel, tin and phosphorus. The combination of nickel and tin increase resistance of the alloy to elevated temperature stress relaxation. As a result, spring contacts formed from alloys of the invention maintain a higher percentage of initially imposed stress at elevated temperatures, in the range of 125 DEG C to 150 DEG C, for significantly longer times than other brass alloys of comparable strength.
