· ZrInAu

ZrInAu is a ternary intermetallic compound combining zirconium, indium, and gold. This material exists primarily in the research domain as an experimental alloy with potential applications in advanced metallic systems, particularly where the unique combination of these elements—zirconium's strength and corrosion resistance, indium's low melting point characteristics, and gold's stability—might offer specialized properties. While not yet established in mainstream industrial production, intermetallic compounds of this type are investigated for high-temperature applications, aerospace components, and specialized electronic or thermal management systems where conventional alloys reach performance limits.
