· Sm1 Tm3

Sm₁Tm₃ is an intermetallic compound composed of samarium and thulium, rare earth elements that form ordered crystal structures with potential for high-temperature and magnetic applications. This material represents an emerging composition in the rare earth intermetallic family, primarily under research and development rather than established commercial production. The Sm-Tm system is of interest for specialized applications requiring rare earth metallurgical properties, though practical deployment remains limited pending demonstration of performance advantages over conventional rare earth alloys and ceramics.

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.
