metal· 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.
