Al4Si
metal· JVASP-109791· Al4Si
Al4Si is an aluminum-silicon intermetallic compound representing a stoichiometric phase in the Al-Si binary system. This material is primarily of research and metallurgical interest, appearing in cast aluminum-silicon alloys where it forms as a constituent phase during solidification; it is not typically used as a standalone engineering material in structural applications. Engineers encounter Al4Si mainly in the context of understanding microstructure development in commercial Al-Si casting alloys (such as A356 or A380), where controlling its formation and morphology can influence mechanical properties and casting quality.

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.
