· JVASP-144594· YCoB4

YCoB4 is a yttrium-cobalt boride intermetallic compound belonging to the rare-earth boride family. This material is primarily investigated in advanced materials research for high-temperature structural applications and specialized coating systems where enhanced hardness and thermal stability are required. YCoB4 represents an emerging class of boride ceramics with potential advantages in extreme-environment engineering, though industrial deployment remains limited compared to established alternatives like tungsten carbides or nickel-based superalloys.

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.
