NiTiNb Wide-Hysteresis Shape Memory Alloy
Verifiedmetal· NiTiNb· Cryofit· Pipe coupling SMA
NiTiNb is a ternary nickel-titanium-niobium shape memory alloy engineered to exhibit wide thermal hysteresis, enabling large temperature differentials between the martensite and austenite phases during thermomechanical cycling. This composition is used in applications requiring high actuation temperatures, damping over broad temperature ranges, or robust recovery behavior under cyclic loading, particularly in aerospace sealing systems, precision actuators, and vibration isolation devices where conventional NiTi alloys lack sufficient thermal span or functional stability.

Safety & Biocompatibility
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.
