· Cu0.2Ni0.39Sn0.41

Cu0.2Ni0.39Sn0.41 is a copper-nickel-tin ternary alloy, a member of the bronze/cupronickel family used in corrosion-resistant and wear-resistant applications. This composition falls within classical bronze metallurgy territory and is typically employed in marine environments, electrical contacts, and bearing materials where corrosion resistance and moderate mechanical strength are required together. The nickel addition enhances corrosion resistance compared to binary copper-tin bronzes, while the tin content provides hardening and wear resistance—making this alloy competitive with commercial cupronickel grades used in seawater piping and desalination equipment.

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.
