AlFe is an aluminum-iron intermetallic compound or aluminum-iron based alloy system. This material family bridges the properties of lightweight aluminum with the strength and stiffness contributions of iron, positioning it between conventional aluminum alloys and higher-density steel alternatives. AlFe compositions are of interest in structural applications where weight reduction and moderate-to-high stiffness are competing demands, though commercial adoption remains limited compared to established Al-Cu, Al-Mg, and Al-Si systems.
