metal· JVASP-14811· Sm
Samarium (Sm) is a rare-earth lanthanide metal with a silvery-white appearance and moderate density. It is primarily used in high-performance permanent magnets (samarium–cobalt magnets) and as an alloying element to enhance corrosion and oxidation resistance in specialty steels and superalloys. Engineers select samarium-based materials for applications requiring strong magnetic properties at elevated temperatures or exceptional thermal stability where conventional ferromagnets would degrade.

Regulatory Screening
Environmental
Export Control
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.
