Co₂As is an intermetallic compound composed of cobalt and arsenic, belonging to the family of transition metal arsenides. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, with applications driven by its unique electronic and magnetic properties inherent to cobalt-based intermetallics. Co₂As and related cobalt arsenides are investigated for potential use in high-temperature applications, magnetic devices, and advanced semiconductor research, where the specific crystal structure and electron configuration provide advantages over single-phase metals or conventional alloys.
