Nitinol shape memory alloy
Nitinol is a unique shape memory alloy composed of nearly equal proportions of nickel and titanium. It is known for two closely related and unique abilities: shape memory effect (recovering a predefined shape when heated) and superelasticity (exhibiting superior elastic recovery when subjected to extreme loads). These properties, combined with its excellent biocompatibility, fatigue resistance and damping properties, make it an indispensable material in advanced technology applications.
Available Grades and Products
Nickel Titanium (also known as Nitinol or NiTi) is in the unique class of shape memory alloys. A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties. Nitinol alloys are typically made of 55%-56% Nickel and 44%-45% Titanium. Small changes in composition can significantly impact the properties of the material. There are two primary categories of Nitinol.
Nickel-Titanium alloy, commonly known as Nitinol, is a high-performance material characterized by its unique thermoelastic martensitic phase transformation. This property enables both a shape-memory effect and superelasticity, allowing the alloy to return to a preset shape when heated or recover its original form after considerable deformation. These adaptive mechanical behaviors make Nitinol ideal for precision applications. The alloy typically consists of 55-56% nickel and 44-45% titanium, and even minor compositional adjustments can significantly impact its performance.
