· TbFe2

TbFe2 is an intermetallic compound combining terbium (a rare-earth element) with iron in a 1:2 stoichiometric ratio, forming a hard, dense metallic phase with significant magnetic properties. This material is primarily of research and specialized industrial interest, used in applications requiring strong magnetostriction or permanent magnetic behavior, such as precision actuators, sensors, and high-performance magnetic devices. TbFe2 is notable for its exceptional magnetostrictive response—the ability to change shape under magnetic fields—making it valuable where conventional magnetic alloys or electromagnets cannot meet performance requirements, though its cost and brittleness limit adoption compared to more common magnetic steel alloys.

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.
