· Co4 Sm2

Co4Sm2 is an intermetallic compound combining cobalt and samarium, belonging to the rare-earth transition metal family of semiconductors. This material is primarily of research interest for magnetic and electronic applications, as samarium-cobalt compounds are well-established in permanent magnet technology and emerging semiconducting phases. Engineers would consider Co4Sm2 specifically for advanced magnetic devices, thermoelectric systems, or specialized electronic components where the unique electronic structure of rare-earth-transition metal phases offers potential advantages over conventional semiconductors or magnetic materials.

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.
