· JVASP-141255· Mg17Al11Si

Mg17Al11Si is an intermetallic compound in the magnesium-aluminum-silicon system, representing a phase that forms in cast Mg-Al-Si alloys used for lightweight structural applications. This material is primarily encountered in the study of magnesium alloy microstructures and phase equilibria rather than as a standalone engineering alloy; it typically exists as a constituent phase within commercial casting alloys like AZ91D or AS-series alloys. Engineers encounter this phase when optimizing heat treatment, improving creep resistance, or tailoring mechanical properties in high-temperature magnesium castings, particularly where enhanced strength or thermal stability is needed compared to simpler binary magnesium alloys.

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.
