· SmErMg2

SmErMg2 is an intermetallic ceramic compound combining samarium, erbium, and magnesium—a rare-earth magnesium system explored primarily in research contexts for high-temperature applications. This material belongs to the family of rare-earth intermetallics being investigated for oxidation resistance, thermal stability, and potential use in advanced structural applications where conventional magnesium alloys fail at elevated temperatures. Its notably higher density compared to light metals makes it better suited for thermal barrier or structural roles where weight is secondary to thermal performance or chemical durability.

Regulatory Screening

Environmental

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.
