· JVASP-98505· Sm2Co7B3

Sm2Co7B3 is a samarium-cobalt-boron intermetallic compound belonging to the rare-earth hard magnetic alloy family. This material is primarily of research interest for high-temperature permanent magnet applications, where the samarium-cobalt base system offers superior thermal stability and coercivity compared to conventional ferrite magnets, with boron addition modifying the microstructure and magnetic properties. Engineers evaluate this composition for specialized electromagnetic devices operating in harsh environments where conventional magnets degrade, though most production applications still rely on optimized SmCo5 or Sm2Co17 variants.

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.
