· Hf1 Ta1 Re2

Hf1Ta1Re2 is an experimental refractory metal intermetallic compound combining hafnium, tantalum, and rhenium—three of the highest melting point elements in the periodic table. This material belongs to the family of ultra-high-temperature ceramics and refractory alloys being researched for extreme thermal environments where conventional superalloys fail; it remains largely in the research phase but represents efforts to develop materials for next-generation aerospace propulsion, hypersonic vehicles, and nuclear applications where temperatures approach or exceed 2000°C.

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.
