Er2AlSi2
metal· JVASP-16254· Er2AlSi2
Er₂AlSi₂ is an intermetallic compound combining erbium, aluminum, and silicon, belonging to the rare-earth metal silicide family. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural components and advanced aerospace systems where rare-earth strengthening and thermal stability are desired. The erbium content provides enhanced hardness and creep resistance compared to conventional aluminum silicides, making it a candidate material for next-generation turbine engines and thermal barrier systems operating in extreme environments.

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.
