Nitinol wire, known for its unique properties of shape memory and superelasticity, has revolutionized various industries with its exceptional strength and versatility. 

Yes, nitinol rods can bend due to their flexibility and shape memory properties. They can be deformed into various shapes while in their martensitic phase, which is stable at lower temperatures. Upon heating, typically above a specific transition temperature, they revert back to their original shape (austenitic phase). This ability to bend and recover their shape makes nitinol rods valuable in applications requiring controlled and repeatable movements, such as in medical devices, robotics, and aerospace components where precise actuation and flexibility are crucial.

Nitinol wire is a type of shape memory alloy primarily composed of nickel (Ni) and titanium (Ti). Known for its unique properties, nitinol can undergo deformation at lower temperatures and return to its original shape when heated above a specific transformation temperature. This ability is due to a reversible phase transformation between austenite and martensite phases. Nitinol wire exhibits superelasticity, allowing it to endure large deformations and recover without permanent damage. These characteristics make nitinol wire valuable across various industries, including aerospace, medical devices, robotics, and consumer electronics, where precise control, resilience, and shape recovery are essential requirements.

The typical service life of a nitinol guide wire depends on various factors such as usage frequency, application, and operating conditions. In minimally invasive procedures like angioplasty, it can usually last for a single procedure or a few uses if properly sterilized and maintained, generally ranging from several minutes to a few hours per use.

The elastic modulus of nickel titanium wire varies depending on the phase state it is in, as follows:
- Austenite: The elastic modulus is generally 75-83GPa.
- Martensite: The elastic modulus is usually between 28 and 40GPa.

Typical applications for stretched nickel titanium ingot include making medical stents because it has shape memory and superelasticity to support blood vessels. They are also used in orthodontic wire to provide gentle and constant force for orthodontics. In the aerospace sector, it can be used to make components such as connectors that need to maintain performance under different conditions.

The manufacturing process of The manufacturing process of super elastic nitinol pipes usually involves several steps. Firstly, raw materials of nickel and titanium are melted and alloyed through vacuum induction melting. Then, the alloy is formed into tubes by methods like extrusion or drawing. After that, heat treatment processes such as annealing are carried out to obtain the super elastic properties. usually involves several steps.

Titanium nickel springs have obvious advantages over other materials.
In terms of elasticity, nickel-titanium springs have superelasticity. It can recover under large strain, the strain can be as high as 8-10% or so, while the ordinary metal spring strain is generally 1-2%, which makes the nickel-titanium spring can still work normally after enduring large deformation.

Nickel titanium paper clips have several applications in daily life. They can be used to hold papers together firmly. Due to their shape memory property, they can return to their original shape even after being bent or deformed slightly, providing long-lasting use. They are also useful for organizing documents and keeping them in order. Additionally, their unique material can make them more durable than traditional paper clips.
