· JVASP-110222· LaAlSi

LaAlSi is an intermetallic compound combining lanthanum, aluminum, and silicon, representing a rare-earth metal system typically studied for high-temperature and lightweight structural applications. This material belongs to the family of rare-earth aluminum silicides, which are of primary interest in research contexts for aerospace and advanced manufacturing where thermal stability and reduced density are critical. Engineers would consider LaAlSi primarily in experimental or specialized applications where the combination of rare-earth strengthening and intermetallic bonding offers advantages over conventional aluminum alloys or titanium-based systems.

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.
