· JVASP-79462· Ti2AlNi

Ti₂AlNi is an intermetallic compound combining titanium, aluminum, and nickel, belonging to the family of titanium-based intermetallics that exhibit high strength-to-weight ratios and elevated temperature stability. This material is primarily of research and developmental interest for aerospace and high-temperature structural applications, where its potential to operate at temperatures exceeding conventional titanium alloys makes it attractive for engine components and hypersonic vehicle structures. Engineers consider intermetallics like Ti₂AlNi when conventional alloys reach their performance limits, though processing challenges and brittleness at lower temperatures remain active areas of investigation in materials development.

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.
