· JVASP-99990· HfTa2VC4

HfTa2VC4 is a refractory metal carbide composite combining hafnium, tantalum, vanadium, and carbon. This is a research-phase high-entropy or complex carbide material designed for extreme-temperature applications where conventional superalloys reach their limits. The material belongs to the family of transition metal carbides, which are notable for exceptional hardness, melting point resistance, and chemical stability—making them candidates for next-generation aerospace propulsion, thermal protection, and wear-resistant applications where conventional materials fail.

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.
