Nitinol Wire

For medical applications (Nitinol # 1, Nitinol # 2, Nitinol # 4 and Nitinol # 8) and Nitinol # 5, Nitinol # 6 and Nitinol # 9, Fort Wayne Metals are suitable for a variety of other uses. All grades of Nitinol can be heat treated as cold working (CW) conditions or as superelastic (SE) wire extending straight. Fort Wayne Metals has developed a new technology that provides unique mechanical properties called Nitinol called Dynamic Plateau Strength (DPS). This process is also possible. If you need a particularly smooth surface, we recommend using SilkTM Nitinol Wire. This achieves a surface texture of 3 μin RMS without mechanical or electrolytic polishing.

Each medical grade nitinol material consists of approximately equal atomic weight percent nickel and titanium. Our most common medical grade NiTi # 1 is beyond the chemical requirements of the surgical implants specified in ASTM F 2063. In Fort Wayne Metals, all incoming Nitinol raw materials are inspected to ensure that they meet their own internal specifications for chemistry, ingot transition temperature, material uniformity, and microstructure. All wire products are optimized to provide extremely smooth and uniform surface quality with unique single crystal and polycrystalline diamond wire drawing wire technology. Medical Nitinol wires can be purchased in cold working (CW) or superelastic conditions (SE) and correspond to strains of up to 8% after correct superelastic heat treatment without permanent twisting at body temperature. Transition temperature and mechanical properties of our three standard grade Nitinol are listed in the table at the bottom of the page.

Our Nitinol wire is used in many different medical and industrial applications. The table below shows typical engineering applications for each of our standard Nitinol medical grades.

Ideal for applications requiring high load and unloading platform stress at room temperature

Excellent riding performance at body temperature (37 ° C), such as orthodontic archwire

Pickling - chemical removal of oxide layer and small amount of base metal - the surface is rough texture.

Etching and mechanical polishing - chemical removal of oxide layer followed by mechanical polishing - the surface looks like stainless steel (magnification is> 40 times but microscratches occur).

X-ray diffraction (XRD), transmission electron microscope (TEM), Auger electron spectroscopy (AES), scanning electron microscope (SEM), electron dispersion spectroscopy (EDS)

Permanent helix Nitinol wire, thin insulated copper wire attached to the end of Nitinol (one of the copper wires is wrapped around the nickel-nickel alloy so they all go out of the same end of Nitinol ing). We have developed the final SMP coating. Using the SMP attribute, the device is fixed in a straight line. Since Joule heating is carried out by passing an electric current through the copper wire, it exceeds the SMP switching temperature, and superelastic recovery of Nitinol can be achieved. After the current is blocked, the SMP is vitrified, forcing the use of Nitinol and allowing to remove the clot in the body without the need for other common guide wires.

Using shape memory nitinol wires, they can be delivered into the body in a compact form, and then they can be activated into a functional form once they are deployed. When it is necessary to provide a wire of a specific shape according to a specific application, shape setting is prepared. This will "set" the lines that specifically match the device design requirements. We not only manufacture Nitinol in various forms but also manage the entire process from start to finish, making it the world's leading fusion of Nitinol to the medical equipment industry - Completion source
