· JVASP-11946· CoNi

CoNi is an equiatomic or near-equiatomic cobalt-nickel alloy, a binary transition metal system combining the strength and corrosion resistance of cobalt with nickel's ductility and thermal stability. It is used in high-performance applications requiring a balance of mechanical strength, oxidation resistance, and wear resistance, particularly in aerospace engine components, tooling, and biomedical implants where corrosion and biocompatibility are critical concerns. CoNi alloys are notable for their ability to maintain properties at elevated temperatures and superior corrosion performance in aggressive environments compared to 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.
