· JVASP-21567· VCoB3

VCoB3 is a vanadium-cobalt boride intermetallic compound belonging to the hard ceramic-metal (cermet) family. It is an advanced research material being developed for ultra-high-hardness and wear-resistant applications where traditional cemented carbides reach performance limits. The material combines the hardness of boride ceramics with metallic toughness, making it of particular interest for cutting tools, abrasive applications, and extreme-wear environments, though industrial adoption remains limited as the material is still in development stages relative to established alternatives like tungsten carbide.

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.
