HoScAl2

HoScAl2 is a ternary intermetallic compound containing holmium, scandium, and aluminum, representing an experimental rare-earth aluminum system. This material is primarily of research interest in the context of lightweight structural materials and potential high-temperature applications, as rare-earth aluminum intermetallics can exhibit improved strength-to-weight characteristics and thermal stability compared to conventional aluminum alloys. While not yet established in mainstream industrial production, compounds in this family are being investigated for advanced aerospace and defense applications where weight reduction and thermal performance are critical.
