FeAu is an intermetallic compound combining iron and gold, belonging to the family of noble-metal alloys with high density and significant elastic stiffness. While not widely used in high-volume commercial applications, FeAu and related Fe–Au systems are studied in research contexts for specialized applications requiring the unique combination of gold's chemical stability and corrosion resistance with iron's strength and cost advantages. This material is notable in materials science for understanding phase behavior in precious-metal alloys and for potential use in applications where chemical inertness, high density, or specific electronic properties justify the cost of gold content.
