KRbAu2 is an intermetallic compound combining potassium, rubidium, and gold in a stoichiometric ratio. This is an experimental research material rather than an established engineering alloy; it belongs to the family of ternary alkali-gold intermetallics being studied for fundamental properties and potential advanced applications. The compound's notable characteristics include relatively low stiffness combined with unusual elastic properties (reflected in its Poisson's ratio), making it of interest to researchers investigating novel metallic phases, phonon engineering, or thermoelectric and electronic device concepts.
