· Al1 Fe2 Si1

Al₁Fe₂Si₁ is an intermetallic compound combining aluminum, iron, and silicon in a 1:2:1 stoichiometric ratio. This material belongs to the aluminum-iron-silicon ternary system, which has been studied primarily in research contexts for potential lightweight structural applications and as a strengthening phase in aluminum alloys rather than as a monolithic engineering material. The compound's appeal lies in its potential to combine aluminum's light weight with iron and silicon's strengthening contributions, though practical applications remain limited; it is more commonly encountered as a precipitate or reinforcing phase within cast aluminum alloys (such as Al-Fe-Si casting alloys) used in automotive and aerospace components.

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.
