· Sm2Co17

Sm2Co17 is a samarium-cobalt permanent magnet alloy belonging to the rare-earth magnet family, known for its high magnetic strength and exceptional thermal stability at elevated temperatures. This material is widely used in demanding aerospace, defense, and industrial applications where reliable magnetic performance must be maintained in harsh thermal environments, and it offers superior temperature resistance compared to competing ferrite or alnico magnets, though typically at higher cost. Engineers select Sm2Co17 when operating conditions exceed the thermal limits of other permanent magnets or when compact, high-strength magnetic circuits are critical to system design.

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.
