· JVASP-141325· Hf2Co21B6

Hf2Co21B6 is an experimental intermetallic compound combining hafnium, cobalt, and boron, belonging to the family of refractory metal borides and intermetallics. This material is primarily of research interest for high-temperature structural applications, where the hafnium content provides oxidation resistance and the cobalt-boron matrix contributes to hardness and strength. While not yet commercialized at scale, materials in this chemical family are investigated for extreme-environment aerospace and energy applications where conventional superalloys reach their performance limits.
