· JVASP-152583· LaCo4B

LaCo₄B is an intermetallic compound combining lanthanum, cobalt, and boron, belonging to the rare-earth transition metal boride family. This material is primarily of research and developmental interest, investigated for high-strength applications where the combination of rare-earth elements and refractory boride phases offers potential advantages in hardness, thermal stability, and wear resistance. Its use remains largely confined to materials science exploration rather than established industrial production, making it most relevant for engineers evaluating advanced wear-resistant coatings, high-temperature structural applications, or specialized tooling where conventional alloys reach performance limits.

Export Control

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.
