NbB2W
metal· JVASP-106765· NbB2W
NbB2W is a refractory metal boride composite combining niobium, boron, and tungsten—a research-phase material designed to exploit the high hardness of boride ceramics with the toughness and thermal conductivity benefits of metal matrices. This class of materials targets extreme-environment applications where conventional superalloys or monolithic ceramics fall short, offering potential advantages in wear resistance, thermal stability, and machinability compared to pure ceramic borides or single-phase refractory metals.

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.
