Al3 Ni2

Al₃Ni₂ is an intermetallic compound formed from aluminum and nickel, belonging to the class of ordered metallic phases that exhibit semiconductor-like electronic properties. This material is primarily of research interest in advanced aerospace and high-temperature applications, where its potential for lightweight structural performance and thermal stability is being investigated, though it remains less established in production than competing nickel-aluminum superalloys. Al₃Ni₂ represents the broader family of Al-Ni intermetallics, which are studied as alternatives to conventional superalloys due to their lower density and potential for enhanced specific strength at elevated temperatures.
