· HfV2

HfV₂ is a refractory intermetallic compound combining hafnium and vanadium, belonging to the family of high-melting-point binary metals. This material is primarily of research and development interest rather than a widespread industrial standard, with potential applications in extreme-temperature structural applications and advanced aerospace systems where conventional superalloys reach their thermal limits. The hafnium-vanadium system is investigated for high-temperature strength and refractory properties, though practical engineering adoption remains limited due to processing challenges, oxidation sensitivity, and cost considerations compared to established titanium or nickel-based alternatives.
