What Is The Nitinol Alloy?
Nitinol, also called NiTi shape memory alloy, is a metal alloy composed of nickel and titanium, typically in a near 1:1 ratio. It has a unique shape-memory effect and superelasticity, allowing it to return to a preset shape when heated or recover its original form after significant deformation. It offers an expansion rate of over 20%, a fatigue life of 107 cycles, damping properties ten times greater than regular springs, and superior corrosion resistance compared to stainless steel. Due to its excellent biocompatibility, corrosion resistance, and mechanical properties, Nitinol alloy is widely used in medical devices (e.g., stents and orthodontic wires), aerospace, industrial manufacturing, and consumer products.
Fil de nitinol
Nitinol Wire is known for its unique shape memory effect and superelasticity. At room temperature, Nitinol wire can undergo significant deformation and fully recover its original shape, while heating it to a specific temperature triggers its ability to “remember” and return to a pre-set form. It also has excellent biocompatibility, corrosion resistance, and high fatigue life, making it widely applied in medical devices. HM can offer customized solutions for wire type, diameter, and surface state according to specific requirements.

Nitinol Wire Surface Finish
- Noir: La surface est "telle que sertie" ou "telle qu'étirée", conservant une couche de lubrifiants et d'oxydes de traitement.
- Nettoyé: La surface est nettoyée chimiquement pour éliminer tous les lubrifiants et oxydes.
- Sol: La surface est décentrée afin d'éliminer tous les revêtements et d'obtenir un contrôle précis des dimensions.
Nitinol Wire Applications
- Domaine médical: Nitinol wire is commonly used in orthodontics, vascular stents, guide wires in minimally invasive surgeries, and orthopedic implants, due to its good elasticity, shape memory properties, and biocompatibility.
- Industry and Machinery: Leveraging the sensitivity of Nitinol wire to temperature changes, it can be used to make thermal switches or automatic adjustment valves. Additionally, it serves as a vibration-damping material in mechanical systems to absorb vibration energy.
- Consumer Products: The superelasticity of Nitinol wire makes eyeglass temples highly durable, resistant to deformation, and provides a comfortable fit.
Nitinol Wire Packaging
Nitinol Wire products are carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
