Er6 Ru4

Er6Ru4 is an intermetallic compound combining erbium (a rare-earth element) and ruthenium in a 6:4 atomic ratio, representing a member of the rare-earth–transition-metal alloy family. This material is primarily of research and developmental interest rather than established commercial production, with potential applications in high-temperature structural applications, magnetic devices, or advanced functional materials that exploit rare-earth and noble-metal properties. Engineers would consider this compound in specialized contexts where rare-earth magnetism, corrosion resistance, or extreme thermal stability offer advantages over conventional alloys, though limited industrial deployment means such use remains exploratory or niche.
