Fe2AsAu is an intermetallic compound combining iron, arsenic, and gold in a fixed stoichiometric ratio, belonging to the class of metallic intermetallics rather than conventional alloys. This material is primarily encountered in materials research and specialized metallurgical studies rather than mainstream industrial production, where it serves as a model system for understanding phase stability and mechanical behavior in precious-metal-bearing intermetallic systems. Its combination of gold content with iron and arsenic creates unique crystallographic properties that make it relevant for researchers investigating high-performance intermetallics, though practical engineering applications remain limited due to cost, toxicity concerns (arsenic), and availability constraints compared to conventional gold alloys or iron-based materials.
