· Cu0.1Ni0.49Sn0.41

Cu0.1Ni0.49Sn0.41 is a copper-nickel-tin ternary alloy, a member of the bronze/cupronickel family that combines nickel's corrosion resistance with tin's strengthening effect. This composition sits within the range historically explored for marine hardware, electrical contacts, and corrosion-resistant springs where a balance of workability, strength, and seawater resistance is needed. The high nickel content (49%) makes it particularly suited to environments where cupronickels excel, while tin addition (41%) provides additional hardening; however, this specific ratio is not a common commercial standard, suggesting it may represent either a specialized industrial variant or a composition investigated in materials research for optimizing cost and performance trade-offs in demanding corrosive 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.
