CuNi2Sn
metal· CuNi2Sn
CuNi2Sn is a copper-nickel-tin ternary alloy that combines the corrosion resistance of cupronickel systems with tin's strengthening and wear-resistance characteristics. This material is primarily encountered in marine and corrosion-critical applications where seawater exposure demands exceptional resistance to dezincification and biofouling, as well as in bearing and friction applications where tin provides solid-solution strengthening and improved machinability. Engineers select this alloy family when standard brasses prove inadequate in harsh chloride environments or when cost-effective alternatives to pure cupronickel are needed without sacrificing performance.

Export Control
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.
