Deformation Processing of Lead‐Free Duplex Brass

Duplex Brass is used extensively in the plumbing industry. It has the best known combination of processing characteristics, strength and corrosion resistance. In 2014, Pb was legislated to a maximum of 0.25% in plumbing products in the US. As a result several new 'Pb-free' alloys have started entering the market. The optimization of these new alloys has been very empirical to date. Therefore, this research examines in detail the processing-structure-property relationships for these alloys. It is inclusive of studies on phase equilibria, hot workability, machinability and corrosion resistance.
