K2AsAuF6

K2AsAuF6 is a mixed-metal fluoride compound containing potassium, arsenic, gold, and fluorine—a rare intermetallic or coordination compound rather than a conventional alloy. This material exists primarily in research and specialized laboratory contexts rather than mainstream industrial production, and belongs to the family of complex metal fluorides that are investigated for their unique crystallographic properties and potential applications in advanced materials science. The presence of gold and arsenic makes it notable for fundamental studies in solid-state chemistry and materials design, though its practical engineering applications remain limited and largely exploratory.
