· JVASP-109736· HfTiB4

HfTiB4 is a refractory metal boride compound combining hafnium, titanium, and boron—a ceramic-metallic material belonging to the ultra-high-temperature boride family. This is a research-phase material designed for extreme thermal environments where conventional superalloys fail, with potential applications in hypersonic vehicles, rocket nozzles, and advanced aerospace propulsion systems where materials must withstand sustained temperatures above 2000°C while maintaining structural integrity.

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.
