· JVASP-106648· Sm2MgNi2

Sm2MgNi2 is an intermetallic compound combining samarium, magnesium, and nickel, belonging to the rare-earth metal alloy family. This material is primarily of research interest for hydrogen storage and energy applications, as ternary rare-earth magnesium-nickel systems have demonstrated significant potential for reversible hydrogen absorption and desorption cycles. While not yet widely deployed in production engineering, compounds in this family are being investigated as alternatives to conventional hydride materials for stationary and mobile hydrogen storage due to their enhanced thermodynamic properties and cycling stability.

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.
