· Tb2Fe17

Tb2Fe17 is an intermetallic compound in the rare-earth iron system, combining terbium with iron in a fixed stoichiometric ratio. This material is primarily of research and development interest for high-performance magnetic applications, where the rare-earth element provides enhanced magnetic properties compared to conventional ferromagnetic alloys. It is not widely deployed in commodity production but represents an important candidate material in the rare-earth permanent magnet and magnetostrictive device families.

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.
