Product Description
Product Description
Nitinol Wire Description:
Nitinol round wire, also known as NiTi wire, is a nickel-titanium alloy celebrated for its shape memory effect, superelasticity, and outstanding fatigue and corrosion resistance. When deformed, it remarkably returns to its original shape at a specific transformation temperature. These unique traits make Nitinol the material of choice for minimally invasive medical devices, including braided products, orthodontic wires, guidewires, and various implantable surgical tools.

Delivered Transformation Temperature
As a key indicator of superelastic performance in NiTi alloys, the Austenite Finish Temperature (Af) is commonly used to evaluate the effectiveness of superelasticity. According to ASTM F2063-18, the nickel content in NiTi alloys should be within 54.5–57.0 mass%. However, since the Af temperature is highly sensitive to slight variations in nickel content, it is crucial to subdivide the alloy composition. Therefore, refined alloy codes are adopted to clearly identify and control the alloy grades.
