· JVASP-21475· Sm5Co2

Sm₅Co₂ is an intermetallic compound combining samarium (a rare-earth element) with cobalt, belonging to the family of rare-earth transition-metal alloys. This material is primarily of research and specialized industrial interest, valued for its potential in high-temperature applications and magnetic systems where the rare-earth component can contribute to magnetic performance. The samarium-cobalt system has been explored historically for permanent magnet development and high-temperature structural applications, though Sm₅Co₂ specifically remains a niche composition compared to more common SmCo₅ and Sm₂Co₁₇ variants used in commercial permanent magnets.

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.
