· Be3 Fe1

Be₃Fe₁ is an intermetallic compound combining beryllium and iron in a 3:1 ratio, belonging to the class of lightweight metallic intermetallics. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in aerospace and high-temperature structural applications where the low density of beryllium combined with iron's strength could offer weight savings. The compound represents an exploratory effort to leverage beryllium's exceptional strength-to-weight ratio in engineered alloy systems, though practical adoption faces challenges related to beryllium's toxicity in processing and the brittleness characteristic of many beryllium-based intermetallics.
