Hf9CoRe4
metal· JVASP-133304· Hf9CoRe4
Hf9CoRe4 is a refractory high-entropy alloy (HEA) based on hafnium, cobalt, and rhenium, designed for extreme-temperature applications where conventional superalloys reach their limits. This material belongs to the family of multi-principal-element alloys being actively researched for next-generation aerospace and power-generation systems, offering potential advantages in strength retention and oxidation resistance at elevated temperatures compared to traditional nickel-based superalloys.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
