· JVASP-11947· Co3Ni

Co3Ni is an intermetallic compound composed of cobalt and nickel in a 3:1 ratio, belonging to the family of transition metal intermetallics. This material combines the high-temperature strength and magnetic properties characteristic of cobalt-based systems with nickel's corrosion resistance and ductility, making it of particular interest for advanced engineering applications. Co3Ni is primarily explored in research and specialized industrial contexts rather than as a commodity material, with potential applications in high-performance aerospace components, magnetic devices, and wear-resistant coatings where the synergy between cobalt's hardness and nickel's toughness provides advantages over single-element alternatives.

Export Control

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.
