Mg7Fe is an intermetallic compound in the magnesium–iron system, combining a lightweight magnesium-rich matrix with iron for enhanced strength and stiffness. This material is primarily investigated in research and advanced development contexts for applications requiring the low density of magnesium with improved mechanical performance, particularly where conventional Mg alloys or pure iron are insufficient. Its high strength-to-weight ratio and potential for controlled degradation make it a candidate for biomedical implants and aerospace components, though industrial adoption remains limited compared to established Mg alloys (AZ91, AM60) or lightweight aluminum alternatives.
