· JVASP-59686· NbCoB2

NbCoB₂ is a ternary intermetallic compound combining niobium, cobalt, and boron, belonging to the family of high-hardness refractory metal borides. This material is primarily investigated in research settings for applications requiring extreme hardness and thermal stability, with potential use in wear-resistant coatings, cutting tools, and high-temperature structural applications where conventional tool materials prove 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.
