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.

Nitinol Rod is known for its unique shape memory effect and superelasticity. At room temperature, the Nitinol rod 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. There are two main types of superelastic and shape-memory materials based on their transition temperature. HM can offer customized solutions for diameter and surface state according to specific requirements.

Nitinol Rod 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 Rod Applications
Domaine médical:
- Orthopedic Implants: Nitinol bars are widely used in orthopedics, such as for spinal fixation, fracture repair, and artificial joints.
- Dental Equipment: Nitinol bars make dental orthodontic wires and endodontic tools, offering excellent flexibility and shape memory.
- Vascular Stents: Nitinol bars can be made into vascular stents, used to treat arterial stenosis or aneurysms.
Industrial Applications:
