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 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.
