· Zr3 Al1

Zr3Al1 is an intermetallic compound combining zirconium and aluminum in a 3:1 atomic ratio, belonging to the family of refractory intermetallics with semiconductor electronic characteristics. This material is primarily of research and development interest for high-temperature structural applications, where its combination of low density and high-temperature stability offers potential advantages over conventional superalloys. While not yet widely deployed in production engineering, Zr-Al intermetallics are being investigated for aerospace and advanced thermal applications due to their promise in balancing mechanical performance across elevated temperature ranges.
