· JVASP-109401· HfTiRu2

HfTiRu2 is a ternary intermetallic compound combining hafnium, titanium, and ruthenium—a research-phase material belonging to the family of high-entropy and refractory metal alloys. This composition targets extreme-environment applications where conventional superalloys reach their limits, leveraging the high melting points and oxidation resistance of hafnium and ruthenium combined with titanium's strength-to-weight characteristics. While not yet in widespread commercial production, materials in this chemical family are being investigated for next-generation aerospace propulsion, high-temperature structural applications, and defense systems where performance at elevated temperatures and resistance to thermal cycling are critical differentiators over traditional nickel or cobalt-based superalloys.

Export Control

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.
