Low temperature nitinol (NiTi) wire is a type of shape memory alloy wire that can be programmed to return to a specific shape at a lower temperature than traditional NiTi wires. Shape memory alloys have the unique ability to "remember" their original shape and return to it when subjected to a particular temperature, making them useful in various applications such as biomedical devices, aerospace engineering, and robotics.

The lower temperature range of low-temperature NiTi wire typically ranges from -50°C to 20°C. This lower activation temperature makes it ideal for applications where higher temperatures could cause damage or deformation to the surrounding materials.

Low-temperature NiTi wire is often used in biomedical applications, such as orthodontic braces and stents, where it can be used to apply a constant force to the teeth or vessels without causing discomfort to the patient. It is also used in various industrial and commercial applications, such as actuators, dampers, and sensors.

In summary, low-temperature NiTi wire is a specialized type of shape memory alloy wire that can return to a specific shape at lower temperatures than traditional NiTi wires, making it ideal for applications where high temperatures could cause damage or deformation.
