· HoInAu2

HoInAu₂ is an intermetallic compound combining holmium (rare earth), indium, and gold in a fixed stoichiometric ratio. This ternary metallic system is primarily a research material studied for its physical and mechanical properties rather than a widely commercialized engineering alloy. Intermetallic compounds of this type are investigated for potential applications requiring specific combinations of stiffness, density, and thermal or electronic properties, though practical industrial adoption depends on cost-effectiveness, processability, and performance advantages over conventional alternatives.
