· JVASP-41216· Hf2CuOs

Hf2CuOs is an experimental intermetallic compound combining hafnium, copper, and osmium—a refractory metal system designed for extreme-temperature and high-strength applications. This material belongs to the family of advanced intermetallics under research for aerospace and ultra-high-temperature structural applications where conventional superalloys reach their limits. The hafnium-osmium base provides oxidation resistance and thermal stability, while copper addition may improve processability; however, as a research-stage compound, industrial deployment remains limited and material characterization is ongoing.
