Cu11Ni4Sn5
metal· Cu11Ni4Sn5
Cu11Ni4Sn5 is a copper-nickel-tin ternary alloy belonging to the family of bronze and cupronickel systems, likely developed for applications requiring enhanced strength and corrosion resistance beyond binary copper alloys. This composition sits at the intersection of tin-hardened bronzes and nickel-strengthened coppers, positioning it for marine, electrical, or wear-resistant applications where both mechanical performance and environmental durability are critical. The specific ratio suggests a research or specialized industrial formulation rather than a widely standardized alloy, making it relevant to engineers seeking alternatives to conventional brasses or commercial bronzes in demanding service environments.

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.
