· Hf2Au

Hf2Au is an intermetallic compound combining hafnium and gold, belonging to the class of refractory metal intermetallics. This material is primarily of research and specialized engineering interest rather than a commodity industrial material, studied for applications demanding high-temperature strength, corrosion resistance, and the unique properties that arise from ordered hafnium-gold phases.
