Hf2CoIr
metal· JVASP-41131· Hf2CoIr
Hf2CoIr is a ternary refractory metal intermetallic compound combining hafnium, cobalt, and iridium. This material belongs to the family of high-entropy and multi-principal-element alloys being investigated for extreme-temperature applications where conventional superalloys approach their limits. While primarily in research and development phases, Hf2CoIr and similar compositions are explored for their potential to maintain strength and oxidation resistance in aerospace and power-generation environments exceeding 1200°C, where the combination of refractory elements offers thermal stability advantages over traditional nickel- or cobalt-based superalloys.

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.
