· JVASP-110937· TbFeSi2

TbFeSi₂ is an intermetallic compound combining terbium (a rare-earth element), iron, and silicon. This material is primarily of research interest rather than established commercial production, studied for its magnetic and thermal properties within the rare-earth intermetallic family. Applications are being explored in magnetic devices, magnetocaloric systems, and high-temperature structural applications where the combination of rare-earth strength and iron-based economy offers potential advantages over monolithic alternatives.

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.
