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.
