· Cu0.275Ni0.27Sn0.455

Cu0.275Ni0.27Sn0.455 is a copper-nickel-tin alloy, likely a variant of cupronickel or nickel-silver family composition, designed to balance corrosion resistance, strength, and workability. This alloy combination is relevant for marine, electrical, and decorative applications where copper's conductivity and corrosion resistance are enhanced by nickel and tin additions; it represents a research or specialty formulation optimized for specific performance trade-offs compared to standard cupronickel (90/10 or 70/30) or bronze specifications.

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.
