· JVASP-104572· ErMg5

ErMg5 is an intermetallic compound combining erbium (a rare-earth element) with magnesium, classified as a ceramic material. This compound belongs to the rare-earth magnesium intermetallic family, which is primarily explored in research contexts for high-temperature structural applications and advanced functional materials. ErMg5 and related rare-earth magnesium phases are investigated for potential use in lightweight, high-temperature alloys and composite reinforcements where rare-earth elements can enhance creep resistance and phase stability, though industrial deployment remains limited compared to conventional magnesium alloys or established high-temperature ceramics.

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.
