Titanium nickel tubes introduction:
Titanium nickel tubes is a tube made of nickel titanium alloy. Nitinol is a shape memory alloy that can automatically restore its own plastic deformation to its original shape at a specific temperature, its expansion rate is more than 20%, and its corrosion resistance is better than the best medical stainless steel, which is a very good functional material. In addition to the shape memory function, it also has the characteristics of wear resistance, corrosion resistance, high damping and super elasticity
Product features:
-Shape memory effect: Mention that these tubes remember their original shape even after deformation, which is very useful in many applications.
- Superelasticity: emphasizes its ability to withstand large deformation without permanent damage and to quickly recover.
- Corrosion resistance: indicates resistance to various corrosive environments to ensure long service life.
-Biocompatibility: For medical applications, emphasis is placed on the biocompatibility of nickel-titanium tubes to make them safe for use in the human body.
-Wall thickness range: 0.025-3.0mm
-Outer diameter range: 0.20-15.0mm
-MOQ:1PCS
- Good wall thickness uniformity.
-Material composition and properties comply with ASTM F2063 and GB24627 standards.
- High material purity: loose and metal inclusions ≤12.0um; The area percentage of loose non-metallic inclusions is less than 0.5%.
- Smooth surface: outer surface Ra≤0.4μm, inner surface Ra≤0.6μm.

Titanium nickel tubes Application:
Medical field
- Bracket: titanium nickel tubes are used to make brackets. Their shape memory effects and superelasticity allow them to expand and provide support within blood vessels, helping to keep them open and improve blood flow.
- Orthodontic devices: In orthodontics, they are made into wire. The super elastic nature makes them suitable for continuous and gentle force on the teeth, gradually moving into the correct position.
Aerospace industry
- Structural components: titanium nickel tubes can be used as flexible connectors or structural components. Their ability to withstand deformation and recover helps absorb vibrations and shocks during flight.
Temperature sensing elements: Due to shape memory effects related to temperature changes, they can be used to manufacture temperature sensing elements to monitor and control temperature in aerospace systems.
Automobile industry
- Shock absorber: The superelasticity of titanium nickel tubes is used in shock absorber systems. They can effectively absorb and dissipate the energy generated by road bumps, improving the comfort and stability of the vehicle.
Sensors: Used to manufacture sensors that detect physical parameters such as pressure and temperature to help monitor the vehicle's operating condition and improve safety.
