· Sm2Fe17

Sm₂Fe₁₇ is an intermetallic compound composed of samarium and iron, belonging to the rare-earth iron family of permanent magnet materials. It is primarily investigated for high-temperature magnetic applications where its thermal stability and magnetic properties exceed those of conventional ferrite or alnico magnets. This material is particularly notable in research and specialized industrial contexts for permanent magnet motors, generators, and electromagnetic devices operating in elevated-temperature environments where cobalt-based alternatives (such as SmCo₅) may be cost-prohibitive.

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.
