Sm3Co
metal· JVASP-37585· Sm3Co
Sm₃Co is a samarium-cobalt intermetallic compound belonging to the rare-earth permanent magnet family, specifically an early-generation SmCo magnet composition. This material is primarily used in high-temperature magnetic applications where exceptional magnetic stability and corrosion resistance are required, with particular value in aerospace, defense, and industrial equipment operating in extreme thermal or corrosive environments. Compared to modern Sm₂Co₁₇ variants and NdFeB magnets, Sm₃Co offers a favorable balance of magnetic performance and temperature stability, though it has largely been superseded by higher-performance rare-earth compositions in many new designs.

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.
