Seamless nickel titanium alloy tube is a tubular material made of nickel titanium alloy without welds, with unique properties and a wide range of applications. Here is a detailed introduction about it:

Material composition: mainly composed of nickel and titanium, with nickel content usually controlled at 54.5% -57.0% (mass fraction), the rest being titanium, and may also contain trace amounts of other elements.

Manufacturing process: Usually, hot extrusion, cold drawing and other processes are used for manufacturing. Hot extrusion is the process of heating a nickel titanium alloy billet to a certain temperature and extruding it into a tubular shape through a mold; Cold drawing is the process of stretching pipes at room temperature to further improve their accuracy and performance.

Performance Characteristics

• Shape memory effect: Within a certain temperature range, seamless nickel titanium alloy pipes can automatically return to their original shape when subjected to external deformation and the temperature rises to a specific value.

• Super elasticity: At room temperature, this type of pipe can undergo significant elastic deformation, with a deformation amount of over 8%, and can quickly return to its original state after unloading.

• Corrosion resistance: It has good corrosion resistance and good resistance to acids, alkalis, salts, etc. Its corrosion resistance is better than ordinary stainless steel.

• Biocompatibility: Nickel titanium alloys have good biocompatibility and do not cause significant irritation or adverse reactions to human tissues, making them widely used in the medical field.

Size specifications: The outer diameter range is generally 0.20-15.0mm, the wall thickness range is 0.025-3.0mm, and the length can be customized according to requirements.

Execution standards: Commonly used standards include ASTM F2633, ASTM F2063, etc. These standards provide specific provisions for the chemical composition, mechanical properties, dimensional tolerances, surface quality, and other aspects of seamless nickel titanium alloy pipes.

The core advantage of seamless nickel titanium alloy pipes compared to ordinary stainless steel pipes lies in their unique functional characteristics (shape memory, super elasticity) and better biocompatibility, while also having more outstanding corrosion resistance in specific scenarios.

Comparison of core advantages

• Unique functional characteristics: Seamless nickel titanium alloy pipes have shape memory effect and super elasticity, and can quickly recover to their original state through temperature changes or unloading after external deformation. Ordinary stainless steel pipes only have conventional elasticity and do not have this special function.

• Better biocompatibility: Nickel titanium alloy has no significant irritation to human tissues and can be safely used for implantable medical devices. Ordinary stainless steel has poor biocompatibility and is prone to adverse reactions when implanted in the human body.

• More comprehensive corrosion resistance: Although both have corrosion resistance, nickel titanium alloys exhibit more stability in complex media (such as specific acidic and alkaline environments, human body fluids) and have better corrosion resistance than ordinary stainless steel.

• Stronger deformability: Nickel titanium alloy pipes can withstand elastic deformation of over 8% at room temperature, far exceeding the deformation limit of ordinary stainless steel pipes, making them suitable for scenarios that require large deformations.

Application field

• Medical field: commonly used for manufacturing medical devices such as vascular stents, pacemaker electrode leads, dental orthodontic wires, etc.

• Aerospace field: Due to its excellent corrosion resistance, high strength, and shape memory characteristics, it can be used to manufacture seals, pipeline connections, and other components for aircraft engines.

• Other fields: It also has applications in industries such as petroleum, chemical, and electronics, such as manufacturing casings for petroleum logging instruments and connectors in electronic equipment.
