Al5Fe2

Al5Fe2 is an intermetallic compound in the aluminum-iron system, representing a brittle metallic phase that forms at specific compositional ratios. This material is primarily encountered in cast aluminum alloys and aluminum-steel composite systems rather than as a standalone engineering material, where it forms as a constituent phase during solidification or in diffusion bonding applications. Al5Fe2 is of particular interest to researchers studying aluminum-iron interactions, composite interfacial metallurgy, and high-temperature phase stability, though it remains largely a laboratory and materials science concern rather than a primary structural component in production engineering.
