· Hf2 Co1 Re1

Hf₂Co₁Re₁ is an experimental intermetallic compound combining hafnium, cobalt, and rhenium—a research-stage material in the high-entropy and refractory alloy family. This composition belongs to the broader class of advanced metallic systems being investigated for ultra-high-temperature applications where conventional superalloys reach their limits, though industrial adoption remains limited and material behavior requires further characterization.
