· Fe2As

Fe2As is an intermetallic compound composed of iron and arsenic, belonging to the family of binary metal arsenides. This material exhibits metallic bonding characteristics and moderate stiffness, making it relevant to specialized metallurgical and materials research applications. Fe2As appears primarily in academic and experimental contexts rather than high-volume industrial production, studied for its potential in high-temperature materials, semiconductor applications, and as a model system for understanding intermetallic phase behavior and mechanical properties.
