Nitinol (Nickel and titanium alloy) introduction:
Nickel titanium alloy is a kind of shape memory alloys, shape memory alloy is able to own plastic deformation at a certain temperature automatically restore to the original shape of special alloy its expansion rate is above 20%, the fatigue life of 1 * ten to the seventh, 10 times higher than ordinary spring damping properties, its corrosion resistance is superior to the current medical * * stainless steel, so it can satisfy the application requirement of all kinds of engineering and medicine, is a very * * of the functional materials in addition to memory alloy has a unique shape memory function, but also has high wear resistance corrosion and other excellent characteristics of damping and super elasticity.
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.
Shape Memory & superelastic Nitinol sheet
There are two primary categories of Nitinol. The first, known as "SuperElastic", is characterized by extraordinary recoverable strains and kink resistance. The second category, "Shape Memory" alloys, is valued for the Nitinol's capacity to recover a pre-set shape when heated above its transformation temprature.
