Al5NiRu4

Al5NiRu4 is an intermetallic compound combining aluminum, nickel, and ruthenium in a fixed stoichiometric ratio, representing a ternary metal system with potential for high-temperature structural applications. This material belongs to the aluminum-transition metal intermetallic family, which is primarily investigated in research and development contexts for advanced aerospace and refractory applications where conventional aluminum alloys or superalloys reach their limits. The inclusion of ruthenium—a refractory noble metal—suggests this composition targets extreme oxidation resistance and thermal stability, though it remains largely in the experimental phase rather than in routine industrial production.
