TiAlNi2
metal· TiAlNi2
TiAlNi2 is a intermetallic compound based on the titanium-aluminum-nickel system, representing a research-phase material combining the lightweight and high-temperature potential of titanium aluminides with nickel strengthening. While not yet in widespread commercial use, this alloy family is of interest in aerospace and power generation sectors where high strength-to-weight ratios and thermal stability are critical; intermetallic compounds like this offer superior stiffness and creep resistance compared to conventional titanium alloys, though they typically exhibit lower room-temperature ductility and require careful processing.

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.
