· JVASP-90604· Mg3Al

Mg3Al is an intermetallic compound combining magnesium and aluminum, representing a lightweight metal-based material from the Mg-Al system. This compound is primarily of research and development interest rather than established in large-scale commercial production, being investigated for applications requiring low density combined with structural stiffness. The Mg-Al intermetallic family is explored as a potential alternative to conventional magnesium or aluminum alloys where improved strength-to-weight ratios or high-temperature stability are critical, though manufacturing and processing challenges have limited widespread adoption.
