B4OsW
metal· JVASP-106138· B4OsW
B4OsW is a refractory metal compound combining boron, osmium, and tungsten—a research-phase material designed to exploit the exceptional hardness of borides and the thermal stability of heavy refractory metals. Materials in this family are investigated for extreme-environment applications where conventional superalloys reach their performance limits, though B4OsW remains largely experimental and lacks widespread industrial deployment.

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.
