Vanadium Nitride (VN) is a ceramic-like interstitial compound that combines vanadium metal with nitrogen, forming a hard refractory material with metallic electrical conductivity. It is used in cutting tool coatings, wear-resistant applications, and high-temperature structural components where hardness and thermal stability are critical. Engineers select VN coatings for machining applications and industrial tooling because of its superior hardness and resistance to thermal shock compared to conventional tool steels, though it is typically applied as a thin coating rather than used as a bulk material.

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.
