· Hf43Cu157

Hf43Cu157 is an experimental hafnium-copper intermetallic compound, representing a research-phase material in the refractory metal alloy family. This composition falls within high-entropy or multi-component metallic systems being explored for extreme environment applications where conventional superalloys reach their performance limits. The hafnium-copper system is of academic and industrial interest for potential use in ultrahigh-temperature applications, though such materials typically remain in development stages and are not yet established in routine production.
