· JVASP-55023· Sm4Mg3Co2

Sm4Mg3Co2 is an intermetallic compound combining samarium (a rare earth element), magnesium, and cobalt. This material represents an experimental composition within the rare earth-magnesium-transition metal alloy family, likely of interest for research into high-strength lightweight systems or magnetic applications given its rare earth content. Industrial adoption remains limited; potential engineering value lies in specialized aerospace, magnetic device, or high-temperature structural applications where the combination of rare earth strengthening and magnesium's low density could offer advantages over conventional alloys.

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.
