Huizhou Pengchengrui Technology Co., Ltd.

Nitinol Mesh is a mesh like tubular structure woven or laser engraved from nickel titanium memory alloy wire. Its core advantages lie in shape memory, super elasticity, and biocompatibility, making it a key functional component for minimally invasive intervention and high-end industry.

1、 Material and core characteristics

Composition: Approximately 55% nickel and 45% titanium, with an atomic ratio close to 1:1.

Shape memory effect: Deformation at low temperatures, heating to the phase transition temperature (usually around 37 ℃, close to human body temperature) to restore the original preset shape.

Super elasticity: can withstand 8% -15% strain at room temperature, fully rebound after unloading, far superior to stainless steel.

Biocompatibility: Non toxic, non-magnetic, corrosion-resistant to body fluids, suitable for long-term implantation.

High fatigue life: up to millions of cycles of bending/stretching, not easily broken.

2、 Structure and Preparation Process

(1)Weaving type: Nickel titanium wire (diameter 0.05-0.2 mm) is cross woven into a mesh, with both ends closed into a tube shape, soft and easy to bend.

(2)Laser engraving type: Nickel titanium tubes are laser cut into grids, with strong radial support, short reduction, and good visibility.

(3)Parameter customization: Diameter 1-20 mm, length 5-200 mm, mesh density/shape can be designed as needed.

3、 Core application scenarios

(1)Medical intervention (most mainstream)

Vascular stent: self expanding, compressed during delivery, triggered by body temperature upon release, supports blood vessels, prevents restenosis, and is suitable for coronary and peripheral veins (such as Budd Chiari syndrome).

Thrombotic filter: Temporary/permanent implantation, intercepts thrombus, prevents pulmonary embolism, recyclable design reduces long-term risk.

Biliary/Urethral Stent: Flexibly adapts to tortuous lumens, keeping the lumen unobstructed and reducing tissue damage.

(2) Industrial and specialized fields

Precision filtration: acid and alkali resistant, corrosion-resistant, used for high-precision screening in chemical, water treatment, and biomedical industries.

Flexible drive: robot continuous skeleton, minimally invasive instrument joints, achieving multi degree of freedom bending.

Aerospace: Lightweight and highly elastic structural components, suitable for extreme environments.

4、 Key advantages comparison

VS stainless steel network tube: softer, better elasticity, no permanent deformation, excellent biocompatibility, but higher price.

Compared to ordinary titanium mesh, the memory effect and super elasticity are unique, with stronger support and rebound ability.

5、 Key selection points

(1)Size matching: inner/outer diameter, length, and mesh size are adapted to the target cavity/working condition.

(2)Phase transition temperature: commonly used for medical purposes at 37 ℃, customizable for industrial use.

(3)Weaving/cutting process: The weaving type is softer, and the cutting type has stronger support.

Pengchengrui in Huizhou has newly launched nickel titanium alloy mesh tubes, which are suitable for accessories in medical interventional surgeries, interventional thrombectomy, and filter screens. It can be easily pulled and placed in pipes with an inner diameter of 1mm, and can be easily pulled out without deformation. Full industry chain manufacturing, customizable design.
