· JVASP-121334· Er4MgCo

Er4MgCo is a rare-earth containing intermetallic compound combining erbium, magnesium, and cobalt. This is a research-phase material within the family of rare-earth transition-metal alloys, developed to explore novel magnetic, mechanical, or functional properties not readily available in conventional alloys. While not yet established in mainstream production, materials in this composition family show potential for high-performance applications where rare-earth elements provide magnetic strength, thermal stability, or enhanced electronic properties combined with lighter-weight magnesium constituents.

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.
