· Al4 Fe6 Si6

Al₄Fe₆Si₆ is an intermetallic compound combining aluminum, iron, and silicon—a materials research composition rather than a commercial alloy. This phase belongs to the family of aluminum-iron silicides, which are being investigated for lightweight structural applications and high-temperature performance where the combination of low density (from Al) and thermal stability (from Fe–Si interactions) may offer advantages over conventional aluminum alloys or pure intermetallics. The material remains largely experimental; its practical utility depends on processability and brittleness mitigation, as many aluminum-iron silicides suffer from low ductility at room temperature—a key barrier that limits adoption in load-bearing applications.

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.
