· JVASP-140795· LuCo4B

LuCo₄B is an intermetallic compound combining lutetium and cobalt with boron, belonging to the rare-earth transition metal boride family. While primarily encountered in materials research rather than widespread industrial production, this compound represents an emerging class of hard, high-melting-point materials being investigated for extreme-environment applications where conventional alloys reach performance limits. Engineers would consider LuCo₄B in specialized contexts requiring exceptional hardness or thermal stability, though its scarcity, processing complexity, and limited production scale make it suitable mainly for R&D programs rather than high-volume engineering.

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.
