Nb2C
metal· Nb2C
Niobium carbide (Nb₂C) is a refractory ceramic compound belonging to the transition metal carbide family, characterized by extremely high hardness and melting point. It is employed in cutting tool inserts, wear-resistant coatings, and high-temperature structural applications where conventional metals fail; engineers select it over tungsten carbide or titanium carbide when superior hardness combined with chemical inertness and thermal stability are required in extreme environments.

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.
