· Cu75Ni34Sn91

Cu75Ni34Sn91 is a copper-nickel-tin ternary alloy, likely a variant within the family of cupronickel or nickel-silver (German silver) systems used for corrosion-resistant applications. This composition suggests a material engineered for enhanced strength and corrosion resistance compared to binary copper alloys, combining the durability of cupronickel with tin's hardening and wear-resistance contributions. The alloy is typically employed in marine hardware, electrical contacts, and decorative/functional components where resistance to seawater, stress corrosion cracking, and wear are critical.

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.
