· JVASP-15748· SmAl2Si2

SmAl₂Si₂ is an intermetallic compound combining samarium (a rare-earth element) with aluminum and silicon, belonging to the family of rare-earth metal silicides and aluminides. This material is primarily of research and developmental interest rather than established commercial use, explored for high-temperature structural applications where rare-earth strengthening and oxidation resistance are desired. Its potential lies in aerospace and advanced thermal applications where conventional superalloys reach their limits, though practical engineering adoption remains limited due to processing challenges, cost, and competing alternatives.

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.
