· JVASP-56746· LuAlSi

LuAlSi is a ternary intermetallic compound composed of lutetium, aluminum, and silicon, representing an experimental material within the rare-earth–aluminum–silicon family. While not yet widely established in commercial production, this material system is of research interest for potential high-temperature applications and specialized aerospace or electronic contexts where the combination of rare-earth strengthening with lightweight aluminum-silicon matrices could offer advantages. Engineers considering LuAlSi should verify availability and maturity status, as it remains primarily in development phases rather than established industrial use.

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.
