· JVASP-93786· Ti2H

Ti2H is a titanium hydride intermetallic compound formed by the absorption of hydrogen into titanium metal, representing a distinct phase in the titanium-hydrogen system. While not widely used as a primary structural material in production applications, Ti2H is significant in research and materials processing contexts, particularly in powder metallurgy, metal hydride energy storage, and understanding hydrogen embrittlement mechanisms in titanium alloys. Engineers encounter Ti2H most commonly as an intermediate phase during hydrogen absorption/desorption cycles or as a byproduct in welding and fabrication of titanium components, making knowledge of its properties important for controlling material behavior in hydrogen-rich environments.

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.
