Cu3Ni
metal· JVASP-126996· Cu3Ni
Cu3Ni is a copper-nickel intermetallic compound that combines the corrosion resistance of nickel with copper's thermal and electrical conductivity. It is encountered primarily in aerospace, marine, and high-reliability electrical applications where resistance to seawater corrosion and thermal fatigue is critical, as well as in specialty brazing alloys and wear-resistant coatings. The material's ordered crystal structure and intermediate properties between pure copper and nickel make it valuable in applications requiring both electrical performance and aggressive-environment durability.

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.
