VB2
metal· VB2
Vanadium diboride (VB₂) is a refractory ceramic compound belonging to the transition metal boride family, valued for its exceptional hardness and thermal stability at elevated temperatures. It is used primarily in cutting tool coatings, wear-resistant components, and specialized high-temperature applications where conventional materials fail; its main advantage over competing ceramics is superior hardness combined with reasonable fracture toughness, making it particularly attractive for precision machining and abrasive environments where tool life and cost-per-part matter significantly.

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.
