· Sm1 Co5

SmCo5 is an intermetallic compound belonging to the samarium-cobalt family of rare-earth permanent magnets, characterized by a 1:5 stoichiometric ratio of samarium to cobalt atoms. This material is valued in demanding applications requiring high magnetic strength, excellent thermal stability, and resistance to demagnetization at elevated temperatures, making it preferable to ferrite magnets and competitive with NdFeB in high-temperature environments where cost and availability are secondary concerns. SmCo5 magnets are particularly notable for their superior performance in aerospace, military, and high-temperature industrial settings where reliability and consistent magnetic performance under thermal stress are critical.

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.
