· JVASP-148953· LaCo2

LaCo₂ is an intermetallic compound in the lanthanum-cobalt system, belonging to a family of rare-earth transition metal phases studied primarily for hydrogen storage and magnetothermal applications. This material is of research and emerging technology interest rather than a commodity engineering material, valued for its ability to absorb and release hydrogen reversibly and for magnetocaloric effects that enable magnetic refrigeration cycles.

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.
