· CoBN3

CoBN3 is a cobalt-boron-nitrogen compound that represents an experimental hard material in the refractory ceramics and superhard materials family. Research into cobalt-boron-nitrogen systems focuses on achieving high hardness and thermal stability comparable to established alternatives like cubic boron nitride (cBN) and diamond, with potential advantages in chemical inertness and oxidation resistance. This material remains primarily in development stages, with applications under investigation in extreme-environment cutting and grinding tools where conventional hardness alone is 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.
