Product Details of Shape Memory 0.08mm Nitinol Wire
The 0.08mm Shape Memory Nitinol Wire is a precision intelligent material developed based on nickel-titanium (NiTi) binary alloy. With accurate shape memory effect, excellent superelasticity and biocompatibility, it is specially designed for high-precision scenarios. Through strict composition ratio and precision processing technology, the product achieves stable performance under ultra-fine specifications, and is widely applicable to high-end fields such as minimally invasive medical treatment, precision electronics, and intelligent equipment. It is an intelligent material solution with both flexibility and reliability.
I. Features: Combining Intelligent Response and Precision Performance
- Accurate Shape Memory Effect: Leveraging the unique shape memory properties of nitinol alloy, it can withstand obvious plastic deformation and accurately return to its preset shape when heated to a specific temperature (Af). The temperature for shape recovery can be customized between -50℃~100℃ to meet the needs of different application scenarios.
- Excellent Superelasticity: In the austenite temperature range (above Af), it can achieve recoverable strain up to 8%, and instantly recover to its original shape after unloading without permanent deformation. Its plateau stress ranges from 200 to 600MPa, far exceeding the elastic limit of traditional metals, and the fatigue life is ≥10⁷ cycles, which can withstand repeated deformation impacts for a long time.
- Ultra-fine Precision Specification: The diameter is precisely controlled at 0.08mm with a tolerance of only ±0.004mm, and the roundness tolerance is 1/2 of the dimensional tolerance, ensuring the overall dimensional uniformity of the wire. The ultra-fine specification endows the product with excellent flexibility and operability, which can easily pass through narrow spaces and adapt to micro-structure design.
- Excellent Biocompatibility: Adopting a precise ratio of 55%~56% nickel and 44%~45% titanium, no harmful impurities are added, which meets the medical grade material standards. It has no adverse reactions in contact with human tissues and can be used for long-term implantable medical devices.
- Stable Physical and Chemical Properties: It has good corrosion resistance and oxidation resistance, and can adapt to various complex working conditions such as body fluids and industrial environments; the surface is treated with precision polishing, with low roughness, reducing friction loss with contact components.
