· Cu0.3Ni0.45Sn0.25

Cu0.3Ni0.45Sn0.25 is a copper-nickel-tin ternary alloy, likely a cupronickel or bronze-family composition engineered for corrosion resistance and strength. This material family sees use in marine hardware, electrical contacts, and valve bodies where seawater exposure or corrosive environments demand reliable performance; the nickel addition enhances corrosion resistance while tin contributes to hardness and wear resistance compared to binary copper alloys. If this is a research or proprietary composition, it represents targeted tuning of the classical Cu-Ni-Sn system for specific mechanical or corrosive service conditions.

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.
