metal

· JVASP-17682· UInAu2

UInAu2 is an intermetallic compound combining uranium, indium, and gold in a fixed stoichiometric ratio, belonging to the family of ternary metallic systems with potential for specialized high-density applications. This material is primarily of research and development interest rather than established industrial production, as intermetallics in this composition space are studied for their unique combinations of density, elastic properties, and potential thermal or electronic characteristics. Engineers would consider UInAu2 in contexts requiring high-density metals where radioactive properties of uranium or the electronic/thermal contributions of gold and indium offer functional advantages over conventional alloys.
