AlSe₂ is an intermetallic compound combining aluminum with selenium, belonging to the family of metal-selenium systems that exhibit semiconducting or semi-metallic behavior depending on composition and processing. This material is primarily of research interest rather than established in high-volume production, with potential applications in thermoelectric devices, optoelectronic components, and specialized semiconductor research where the metal-chalcogenide system offers tunable electronic properties. Engineers would consider AlSe₂ for niche applications requiring layered structural characteristics or semiconducting behavior at elevated temperatures, though availability and standardized processing routes remain limited compared to conventional alloys.
