· CoHfN3

CoHfN3 is an experimental interstitial nitride compound combining cobalt and hafnium, belonging to the family of refractory transition metal nitrides. This material is primarily of research interest for high-temperature structural applications, where the hafnium-cobalt nitride system is being investigated for potential use in extreme-temperature environments and as a candidate for next-generation refractory coatings or composites that demand enhanced hardness and thermal stability beyond conventional superalloys.

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.
