· JVASP-62617· UCoB4

UCoB4 is a cobalt-uranium boride intermetallic compound belonging to the transition metal boride family. While not widely documented in mainstream engineering databases, this material likely represents research into high-hardness refractory borides for extreme-environment applications. Uranium borides are explored for specialized nuclear, defense, and high-temperature contexts where conventional ceramics and carbides 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.
