· Er1 Al3

Er₁Al₃ is an intermetallic compound belonging to the rare-earth aluminum family, combining erbium with aluminum in a defined stoichiometric ratio. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural materials, advanced alloys, and electronic or photonic devices leveraging rare-earth properties. Engineers would consider this compound in specialized contexts where rare-earth intermetallics offer advantages in thermal stability, magnetic properties, or electronic behavior—though availability, processability, and cost typically limit adoption compared to conventional aluminum alloys or other established intermetallics.

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.
