· JVASP-34157· Tb2FeSi2

Tb2FeSi2 is an intermetallic compound combining terbium, iron, and silicon, belonging to the rare-earth iron silicide family of advanced metallic materials. This material is primarily of research interest for magnetocaloric and magnetostructural applications, where its rare-earth content enables specialized magnetic functionality; it represents an emerging class of compounds studied for solid-state refrigeration and energy conversion rather than conventional structural or high-temperature engineering roles. Engineers would evaluate this material when designing next-generation cryogenic cooling systems or magnetothermal devices where the magnetocaloric effect of rare-earth intermetallics provides advantages over traditional vapor-compression cooling.

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.
