Lead-free bronze alloys contain no more than 0.25 percent lead on wetted surfaces, the limit set by the U.S. Reduction of Lead in Drinking Water Act that took effect January 4, 2014 (Public Law 111-380). The main families are bismuth bronze (grades C89320, C89833, and C89835), silicon bronze (C87600, C87850), and aluminum bronze (C95400, C95500, C95900). Bismuth bronze typically holds 1 to 3 percent bismuth, which replaces lead as a machining aid. Before 2014, copper alloys were allowed up to 8 percent lead, so the shift to a 0.25 percent ceiling reshaped how plumbing, valve, and bearing parts are specified (Copper Development Association, 2024).
