Polished nickel titanium shape memory alloy wire
Polished nickel titanium shape memory alloy wire is a kind of advanced alloy material with shape memory effect and super elastic properties. It is composed of nickel and titanium, and after special treatment and polishing, it can be made into fine wires or wires, used in fields such as medical, aerospace, automotive, and electronics. This material can automatically restore its original shape when subjected to stress or temperature changes, so it is widely used in the manufacturing of products such as springs, valves, sensors, and medical devices.
Description:
Nitinol is a kind of nickel-titanium alloy with super elasticity and shape memory properties. Shape memory refers to the ability of NiTi alloy to deform at one temperature and then recover its original shape when heated above its transition temperature. Hyperelasticity occurs at a narrow temperature range, just above its transition temperature; in this case, the under formed shape can be restored without heating, and the material shows great elasticity, which is about 10-30 times that of ordinary metal.
