Top 10 Reasons to Use Green Alloys™

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”.

Our GreenAlloys™ have extremely low-lead content, often as low as .05%. 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. Concast manufactures a wide selection of low-lead and no lead bronze and brass alloys, in which we replace lead with other elements while still offering exceptional lubricity, tightness, wear, strength, hardness and machinability.

Thirty of our alloys are produced from recycled content at an average of 85%.
