· Cu0.6Ni0.15Sn0.25

Cu0.6Ni0.15Sn0.25 is a copper-nickel-tin ternary alloy that combines the corrosion resistance of cupronickel with tin's strengthening and wear-resistance contributions, positioning it within the family of high-performance bronze and cupronickel alloys. This composition is employed in marine hardware, electrical contacts, and corrosion-resistant fasteners where superior seawater resistance and mechanical durability are required without the cost premium of pure cupronickel or specialty superalloys. The nickel and tin additions enhance hardness and fatigue resistance compared to binary copper-nickel systems, making it particularly valuable in saltwater piping, pump components, and heat-exchanger tubing where galvanic corrosion and erosion-corrosion are recurring failure modes.

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.
