· JVASP-106343· Nb3B4W3

Nb3B4W3 is a refractory metal compound combining niobium, boron, and tungsten—elements known for exceptional high-temperature stability and hardness. This appears to be a research-phase material within the family of transition metal borides and carbides, developed to achieve ultra-high melting points and wear resistance for extreme-service applications where conventional superalloys reach their limits.

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.
