· CuNi14Sn5

CuNi14Sn5 is a copper-nickel-tin ternary alloy combining the corrosion resistance of cupronickel with tin strengthening, typically used in marine and seawater-exposed environments. This alloy is notable for its biofouling resistance and strength in harsh aqueous media, making it a preferred choice over conventional copper-nickel alloys in naval architecture, desalination systems, and offshore applications where both erosion-corrosion and biological fouling present engineering challenges.

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.
