· JVASP-109350· VCrB4

VCrB4 is a vanadium-chromium boride ceramic compound belonging to the refractory boride family, valued for its exceptional hardness and high-temperature stability. This material is primarily investigated for cutting tools, wear-resistant coatings, and high-performance composite reinforcement in aerospace and industrial machining applications where conventional carbides reach their thermal or mechanical limits. VCrB4 represents an advanced research material offering potential advantages over tungsten carbide in extreme-temperature or corrosive environments, though it remains less commercially established than legacy boride systems.

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.
