Ranging from aluminum bronze to high tin bronze, our GreenAlloys™ are manufactured to ASTM B standards and specifications and meet the requirements of 3874 Reduction of Lead in Drinking Water Act" and California legislation "AB1953." At Concast, we promise to deliver a broad range of alloys of the future that are free of the elements that threaten health and the environment. Our GreenAlloys™ have extremely low-lead content, often as low as .05%. Concast manufactures a wide selection of low-lead and no lead bronze alloys, in which we replace lead with other elements while still offering exceptional lubricity, tightness, wear, strength, hardness and machinability.
Eco Brass®
Eco Brass® C87850 has physical and mechanical properties that provide excellent strength and corrosion resistance characteristics while still maintaining good machinability.
Federalloy®
Federalloy® is a patented alloy in which lead is replaced with bismuth to create pressure-tight plumbing fittings and fixtures. It has excellent machinability. Concast has been the only foundry in the nation licensed to produce the Federalloy® series of lead-free copper alloys. We joined forces with Federal Metal Company, who developed the Federalloy® group of alloys, such as C89831 and C89835.
