Hf3TaFe8
metal· JVASP-121617· Hf3TaFe8
Hf3TaFe8 is a refractory metal intermetallic compound combining hafnium, tantalum, and iron—elements selected for high-temperature strength and oxidation resistance. This is a research-stage material within the high-entropy and refractory alloy family, primarily investigated for extreme thermal environments where conventional superalloys reach their limits. The hafnium–tantalum combination targets aerospace and power generation applications requiring materials that maintain structural integrity at temperatures where nickel-based superalloys begin to degrade.

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.
