· JVASP-18002· TbCoSi

TbCoSi is an intermetallic compound combining terbium (a rare-earth element), cobalt, and silicon in a stoichiometric ratio. This material belongs to the family of rare-earth transition-metal silicides, which are primarily of scientific and specialized engineering interest rather than high-volume industrial use. TbCoSi and related rare-earth silicides are investigated for potential applications in high-temperature structural applications, magnetic devices, and advanced functional materials, though commercial adoption remains limited; engineers would consider this material for niche applications requiring rare-earth magnetic properties or extreme-temperature stability rather than as a general-purpose structural alloy.

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.
