· JVASP-105495· HfNb2VC4

HfNb2VC4 is a high-entropy refractory metal carbide compound combining hafnium, niobium, vanadium, and carbon. This is an experimental material belonging to the ultra-high-temperature ceramic carbide family, developed for extreme thermal and mechanical environments where conventional superalloys reach their limits. The material system shows promise for next-generation aerospace and power generation applications requiring exceptional hardness, thermal stability, and oxidation resistance at temperatures exceeding those handled by traditional nickel-based alloys.

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.
