· Y(AlSi)2

Y(AlSi)₂ is an intermetallic compound combining yttrium with aluminum and silicon, belonging to the class of rare-earth metal silicides and aluminides. This material is of primary interest in advanced metallurgy and composite research rather than established production, where it is investigated for high-temperature structural applications due to the strengthening contribution of rare-earth elements in ceramic-metal systems. Engineers would consider Y(AlSi)₂ primarily in research contexts exploring lightweight, high-stiffness phases for aerospace composites or ceramic matrix composites, where yttrium-containing intermetallics offer potential improvements in creep resistance and oxidation protection at elevated temperatures.

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.
