· JVASP-122171· Sm2Fe15Co2C3

Sm2Fe15Co2C3 is a rare-earth iron-cobalt carbide intermetallic compound, part of the samarium-iron family of materials known for their high magnetic strength and thermal stability. This material is primarily investigated for high-temperature magnetic applications where conventional permanent magnets lose effectiveness, particularly in aerospace and automotive powertrains operating above 200°C. The addition of cobalt and carbide phases enhances coercivity and Curie temperature compared to samarium-cobalt or iron-based alternatives, making it valuable for next-generation motors, generators, and magnetic devices in extreme thermal environments.

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.
