· Sm2 Mg1

Sm₂Mg₁ is an intermetallic compound combining samarium (a rare-earth element) with magnesium in a 2:1 stoichiometric ratio. This material belongs to the rare-earth magnesium intermetallic family, primarily explored in research and advanced development rather than established high-volume production. The compound is of interest for applications requiring combinations of lightweight behavior (from magnesium) and rare-earth functional properties, though industrial adoption remains limited pending cost reduction and property optimization relative to competing lightweight and 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.
