                                                                                                          Knowledge of the medical nickel-titanium flat wire industry

​​​​​​​
1. Industry overview
Market size:

The global market size of medical nickel-titanium alloys was approximately 1.5 billion US dollars in 2023, with an annual growth rate of 8-10%

Flat wire products account for approximately 25% of the share of medical nickel-titanium products

Industrial chain
Upstream: High-purity titanium/nickel raw materials → Midstream: Flat wire processing (rolling, heat treatment) → Downstream: Medical device manufacturing

Regional distribution:

North America (45% market share)

Europe (30%)

Asia-pacific (20%, China has the fastest growth rate)

2. Product Feature Requirements
Core indicators:

Dimensional accuracy: ±0.01mm (required for high-end products)

Phase transition temperature control: ±3℃ (e.g. Af=37℃±3)

Surface roughness: Ra≤0.2μm (implant grade)

Special treatment:

Electrolytic polishing (reducing the risk of thrombosis)

Passivation treatment (to enhance corrosion resistance)

Laser marking (Product traceability)

3.. Technical Barriers
Material preparation

Vacuum melting (oxygen content ≤500ppm)

Multi-pass secondary temperature rolling (precise control of deformation)

Processing difficulties:

Rebound control caused by shape memory effect

The flatness of the ultra-thin specification (< 0.1mm) is maintained

4. Main Application Fields
Cardiovascular intervention

Guide wire (0.1×0.3mm specification)

Skeleton of the occluder

Orthopedics and Dentistry

Orthodontic archwire (0.4×0.6mm, etc.)

Bone repair mesh

Minimally invasive surgical instruments

Endoscope guiding component

Transmission components of surgical robots

5. Industry Development Trends
Technological innovation:

Degradable nickel-titanium flat wire (magnesium alloy composite)

Nano-coating technology (antibacterial/healing promotion)
