Nitinol Wire

nitinol wire coil


Near-atomic ratio of Nitinoal (Ti-Ni alloy) was the first material to be used as a shape-memory alloy. Due to its excellent shape memory function, good heat and corrosion resistance, high strength, unique thermal and fatigue resistance, high biocompatibility and high damping characteristics, it is widely used in many fields.


Nitinol's (Ti-Ni alloy) Phase Transition Temperature is very sensitive to its composition, with each additional 0.1% Ni causing the Phase Transition Temperature to drop 10°C. Adding a third element will also significantly influence the nitinol's Phase Transition Temperature.


Nitinol wire (Titanium - Nickel wire) can be used in cell phone antennas, children's toys, experimental materials, eye glasses components and medical equipment such as surgical stitching wire, birth control loop and high-quality memory alloy wire of other areas.
