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
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.
