· JVASP-107176· ErAl3

ErAl₃ is an intermetallic compound in the rare-earth–aluminum family, combining erbium with aluminum in a defined stoichiometric ratio. This material is primarily of research and developmental interest rather than a mature commercial alloy, with applications emerging in high-temperature structural components and specialty aerospace systems where its combination of light-weight aluminum with rare-earth strengthening offers potential advantages over conventional superalloys. Engineers consider rare-earth aluminum intermetallics when extreme thermal stability, creep resistance, or specialized electronic properties are needed, though cost, processability, and reproducibility remain practical considerations versus established alternatives.

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.
