· JVASP-90121· Ti4H5

Ti4H5 is a titanium-based hydride compound representing a reactive phase in the titanium-hydrogen system, typically encountered as an intermediate phase during hydrogen absorption or processing of titanium alloys rather than as a primary use material. While hydride phases are generally avoided in conventional titanium engineering due to brittleness concerns, Ti4H5 and related titanium hydrides are subjects of active research for hydrogen storage applications, advanced metallurgical processing, and potential use in hydrogen energy systems where controlled hydride formation could be leveraged. The material's significance lies primarily in understanding titanium's hydrogen interaction behavior and in emerging energy technologies rather than traditional load-bearing applications.

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.
