· JVASP-9422· ErAl8Fe4

ErAl8Fe4 is an erbium-aluminum-iron intermetallic compound, representing a rare-earth metal alloy system that combines erbium's nuclear and thermal properties with aluminum and iron for structural compatibility. This material belongs to the family of rare-earth intermetallics and appears to be primarily a research or specialized industrial compound rather than a commodity alloy. Its application is likely driven by niche requirements in nuclear engineering, high-temperature aerospace components, or advanced materials research where rare-earth additions provide benefits in neutron absorption, creep resistance, or phase stability.

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.
