· Al1 Si2 Y2

Al1Si2Y2 is an aluminum-silicon intermetallic compound doped with yttrium, belonging to the class of rare-earth-modified aluminum silicides. This material is primarily of research and developmental interest rather than established in high-volume production; it represents experimental work in creating advanced intermetallic phases with potential for high-temperature structural applications where conventional aluminum alloys fall short. The yttrium addition typically enhances oxidation resistance, creep resistance, and thermal stability compared to binary Al-Si phases, making it a candidate for aerospace and automotive powerplant components operating at elevated temperatures.

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.
