· Mg1 Al2 Si2

Mg₁Al₂Si₂ is an intermetallic compound combining magnesium, aluminum, and silicon—a ternary system exploring lightweight, high-stiffness alternatives within the Mg-Al-Si material family. This compound is primarily investigated in research contexts for potential aerospace and automotive applications where the combination of low density (from Mg and Al) and silicon's contribution to hardness could benefit weight-critical structures; however, practical industrial adoption remains limited compared to conventional Mg alloys or Al-Si casting alloys, and workability and thermal stability are key development challenges.

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.
