Abstract

A composition for a low lead ingot containing primarily copper and including tin, zinc, sulfur, phosphorus, nickel. The composition may contain carbon. The low lead ingot, when solidified, includes sulfur or sulfur containing compounds such as sulfides distributed through the ingot. The presence and a substantially uniform distribution of these sulfur compounds imparts improved machinability and better mechanical properties.
