Nickel-titanium multi-strand wire rope is a specialized type of wire rope made by twisting nickel-titanium alloy wires, combining the unique properties of nickel-titanium alloys with the structural advantages of wire ropes. Below is a detailed introduction to it:

 1. Structural Features

Nickel-titanium multi-strand steel wire ropes are typically formed by twisting multiple nickel-titanium alloy wires according to specific rules, with common structures including 1*2, 1*3, and 1*7. Their diameter generally ranges from 0.15mm to 2.0mm and can be customized as needed.

 2. Performance Features

• Shape memory properties: Nitinol alloy possesses a unique shape memory effect. Under certain conditions, when deformed, it can return to its original shape upon reaching a specific temperature range, making it highly applicable in fields such as aerospace deployable structures.

  
  

• Hyperelasticity: The ability to withstand external forces without permanent deformation within a large range of deformation, quickly returning to the original state upon removal of the force. It is suitable for shock absorption devices, elastic connecting components, and similar applications.

  
  

• Corrosion resistance: The surface of nickel-titanium alloy can form a dense oxide film, which provides excellent corrosion resistance. It can resist the erosion of chemicals such as acids, alkalis, and salts, making it suitable for use in harsh environments like marine engineering and chemical industries.

  
  

• High strength and toughness: Nickel-titanium multi-strand steel cables exhibit high strength and excellent toughness, capable of withstanding significant tensile and impact forces, while remaining resistant to fracture under complex stress conditions such as bending and torsion.

  
  

• Biocompatibility: It exhibits good affinity with human tissues, does not cause significant immune reactions or toxic effects, and is commonly used in the manufacture of medical devices such as cardiovascular stents and orthodontic wires.

  
  

• Fatigue resistance: It exhibits excellent fatigue performance under cyclic loading and unloading conditions, capable of withstanding numerous cycles without fatigue failure, making it suitable for mechanical transmission, lifting equipment, and similar applications.

  
  

• Low friction coefficient: The surface has a low coefficient of friction, resulting in minimal friction when in contact with other objects during use. This reduces energy loss and wear, improving transmission efficiency and service life.
