EnviroBrass III is one of a series of alloys pursued by an industry consortium to develop alloys that meet the National Sanitation Foundation’s standard on low lead pickup in water supply systems. The research showed that a combination of bismuth and selenium provides the same beneficial effect on machinability as does lead. EnviroBrass III contains up to 1.2% Bi and 0.1% Se and is suitable for permanent mold and pressure die castings. SeBiLOY was the original name used to represent these alloys (see SeBiLOY I, Alloy Digest Cu-605, June 1996, and SeBiLOY II, Alloy Digest Cu-606, revised October 1996).
