· Cu0.375Ni0.17Sn0.455

Cu0.375Ni0.17Sn0.455 is a copper-nickel-tin ternary alloy, a member of the bronze/cupronickel family with significant nickel addition for enhanced strength and corrosion resistance. This composition falls within research and specialized industrial space, likely developed for applications requiring improved mechanical properties and seawater corrosion resistance compared to traditional binary brasses or bronzes. Engineers would consider this alloy where moderate-to-high strength, non-magnetic behavior, and biofouling resistance are simultaneously required—such as marine equipment or electrical contacts—though availability and cost compared to standard wrought cupronikel grades warrant evaluation.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
