· TiNi3

TiNi₃ is an intermetallic compound in the titanium-nickel system, representing a stoichiometric phase that forms at specific composition and temperature ranges. This material is primarily of research and materials science interest rather than established commercial production, as it occupies a specific phase region in the Ti-Ni phase diagram alongside more commonly used titanium alloys and shape-memory NiTi compounds.

Regulatory Screening

Environmental

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.
