Er2Al
metal· JVASP-118962· Er2Al
Er₂Al is an intermetallic compound in the rare-earth–aluminum system, representing a research-phase material combining erbium (a lanthanide) with aluminum. This material family is of interest for high-temperature structural applications and specialty aerospace/defense contexts where rare-earth alloying can improve creep resistance, oxidation stability, or specific mechanical properties compared to conventional aluminum alloys. Er₂Al remains largely experimental; its adoption depends on cost-benefit analysis against mature alternatives and demonstration of reproducible processing routes for engineering components.

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.
