· Al1 Si1

Al1Si1 is a 1:1 stoichiometric aluminum-silicon compound in the semiconductor class, representing a theoretical intermetallic or alloy composition rather than a commercial material. This composition sits at the boundary between aluminum-rich aluminum-silicon alloys and silicon-rich semiconductors, making it primarily a research material for investigating phase behavior, crystal structure, and electronic properties in the Al-Si system. While not widely deployed in production applications, materials in this compositional family are relevant to researchers exploring advanced semiconductor interfaces, composite materials, and the fundamental properties of aluminum-silicon phases that occur as secondary phases or grain boundaries in conventional aluminum-silicon casting alloys.

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.
