· ZrAl2

ZrAl2 is an intermetallic compound in the zirconium-aluminum system, characterized by a ordered crystalline structure combining the properties of both constituent elements. This material is primarily of research and development interest for high-temperature structural applications, valued for its potential to offer improved stiffness and thermal stability compared to conventional aluminum alloys, though commercial adoption remains limited. The zirconium-aluminum intermetallic family is being explored in aerospace and advanced manufacturing contexts where weight reduction and elevated-temperature performance are critical design drivers.
