· JVASP-18917· TmCo2

TmCo₂ is an intermetallic compound composed of thulium and cobalt, belonging to the rare-earth transition metal intermetallic family. This material is primarily of research and specialized industrial interest, valued for its magnetic properties and potential high-temperature performance characteristics inherent to rare-earth cobalt systems. TmCo₂ and related RCo₅ and R₂Co₇ intermetallics are investigated for permanent magnet applications and magnetocaloric effects, offering alternatives to conventional rare-earth magnets in niche applications where specific thermal, magnetic, or structural properties align with system constraints.

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.
