SmFe5
metal· JVASP-4355· SmFe5
SmFe5 is an intermetallic compound composed of samarium and iron, belonging to the rare-earth iron family of magnetic materials. It is used primarily in permanent magnet applications where high magnetic strength and thermal stability are required, particularly in electric motors, generators, and magnetic devices operating at elevated temperatures. SmFe5 offers a cost-effective alternative to some higher-performance rare-earth magnets while retaining strong ferrimagnetic properties, making it relevant for applications where performance-to-cost balance is critical.

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.
