· JVASP-154797· Th2Fe17

Th₂Fe₁₇ is an intermetallic compound in the thorium-iron system, belonging to a family of rare-earth and actinide-based metallic compounds studied for advanced magnetic and high-temperature structural applications. This material is primarily of research interest rather than widespread industrial use, valued for its potential in permanent magnets and high-temperature alloys where exceptional magnetic properties or thermal stability are required. Its notable advantage over conventional ferromagnetic materials lies in the possibility of achieving superior magnetic performance through the thorium-iron crystal structure, though practical applications remain limited due to thorium's radioactivity and associated handling constraints.

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.
