· JVASP-143799· Sm2Co5Cu5

Sm₂Co₅Cu₅ is a rare-earth cobalt-based intermetallic compound belonging to the samarium-cobalt permanent magnet family, with copper as a tertiary alloying element. This composition sits within the research domain of high-performance magnetic materials, where the copper addition is investigated for its effects on magnetic properties, thermal stability, and cost optimization relative to traditional SmCo5 magnets. Engineers consider samarium-cobalt alloys for extreme-environment applications requiring superior coercivity and temperature stability compared to conventional ferrite or neodymium magnets, though this specific ternary variant remains primarily a research composition rather than a widely commercialized engineering standard.

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.
