Cu30Ni29Sn41
metal· Cu30Ni29Sn41
Cu30Ni29Sn41 is a copper-nickel-tin ternary alloy, likely a specialized bronze or cupronickel composition designed for corrosion resistance and mechanical strength. This material composition falls within the family of naval brasses and specialized bronzes historically used in marine and chemical environments, where the nickel addition enhances corrosion resistance while tin provides hardening and wear resistance. Engineers select this alloy for applications requiring simultaneous resistance to seawater corrosion, mechanical durability, and good machinability in demanding environments where standard brasses or plain coppers are insufficient.

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.
