· JVASP-141434· Mg8Al4Cu2Si7

Mg8Al4Cu2Si7 is a magnesium-based intermetallic compound combining aluminum, copper, and silicon to form a multi-phase system with potential for lightweight structural applications. This composition belongs to the family of magnesium alloys with complex intermetallic phases, which are of research interest for achieving improved strength-to-weight ratios and elevated-temperature stability compared to conventional wrought magnesium alloys. The specific phase balance in this system may offer benefits in castability and creep resistance, though this particular stoichiometry appears to be a research or developmental composition rather than an established commercial alloy.

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.
