Nickel titanium monofilament fiber is an alloy wire composed of two metals, nickel and titanium. Due to its unique properties, it has a wide range of applications in various fields. Here is an introduction about it:

1、 Performance characteristics:

• Shape memory effect: Nickel titanium monofilament fibers can automatically return to their original shape after being deformed at a certain temperature and heated above a specific transition temperature. For example, a stent made of nickel titanium wire can be compressed at low temperatures for implantation into the human body. After entering the body, it can restore its original state under the action of body temperature and provide support.

  
  

• Super elasticity: It has super elasticity and can maintain elasticity over a large range of strains, withstand greater degrees of tension or bending without permanent deformation, and its strain recovery can reach 8%.

  
  

• Biocompatibility: Nickel titanium monofilament fibers do not cause serious immune or toxic reactions in the human body and can be safely used in medical devices that come into long-term contact with human tissues, such as cardiovascular stents, orthopedic implants, etc.

  
  

• Corrosion resistance: Nickel titanium monofilament fibers can maintain their stability and have good corrosion resistance in various environments, whether it is physiological environment inside the body or humid environment outside the body, where chemical substances exist.

  
  

• High fatigue life: This material has strong durability and is suitable for long-term cyclic use scenarios. It can maintain its performance even after repeated deformation.

2、 Manufacturing process:

Firstly, it is necessary to precisely control the ratio of nickel and titanium for raw material melting, and then use hot processing techniques such as forging and rolling to shape the alloy into wire shape. During the processing, temperature, pressure and other parameters need to be strictly controlled, and some parts will also undergo special surface treatment to improve biocompatibility or enhance corrosion resistance.

3、 Application areas:

• Medical field: In the cardiovascular field, it can be used to manufacture heart stents to help dilate narrow blood vessels; In the field of orthodontics, orthodontic archwires made of nickel titanium wire can provide patients with more comfortable and efficient correction solutions; In orthopedics, it can serve as an auxiliary structure to aid in the repair and fixation of bones.

  
  

• Industrial field: In the aerospace field, it can be used to manufacture connectors that can automatically adjust their shape in environments with large temperature changes; In mechanical manufacturing, it can replace traditional spring materials and be used for shock absorbers in precision instruments.

  
  

• In the daily life field, some high-end eyeglass frames use nickel titanium wire for the legs, which utilizes its super elasticity to allow the frames to withstand large deformations and be less prone to damage, while also adapting to different users' wearing habits.
