· HoAu2

HoAu₂ is an intermetallic compound composed of holmium and gold, belonging to the rare-earth metal alloy family. While primarily of research interest rather than high-volume industrial use, this material exhibits the characteristic properties of rare-earth intermetallics, including high density and notable mechanical stiffness. The holmium-gold system is studied for potential applications in specialized fields where rare-earth metallurgy and precious metal properties converge, though commercial deployment remains limited and material availability is constrained.
