· Hf2 Cu1 Re1

Hf2Cu1Re1 is a refractory intermetallic compound combining hafnium, copper, and rhenium in a fixed stoichiometric ratio. This material belongs to the family of high-temperature intermetallics and is primarily of research and development interest rather than established commercial production. The hafnium-copper-rhenium system is explored for ultra-high-temperature applications where oxidation resistance, strength retention, and thermal stability are critical, though adoption remains limited compared to conventional nickel-based superalloys and tungsten-based refractory metals.

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.
