Product Details
Product Features
Platinum group alloys (Pt, PtIr10)
1. Exceptional Radiopacity: Exceptionally high X-ray opacity ensures precise positioning during surgery.
2. Biocompatibility: Harmless to human tissues, with extremely high safety.
3. Excellent electrical performance: an ideal electrode material.
4. Strong corrosion resistance: Long-term stability in the body without degradation.
Tantalum / Niobium
1. Excellent Imaging Performance: With high density second only to platinum, it delivers clear imaging results.
2. Excellent tissue affinity: It exhibits excellent biocompatibility with human tissues and promotes tissue healing.
3. Excellent Corrosion Resistance: The internal environment is extremely stable.
4. High hardness: Provides structural strength and wear resistance.
Cobalt-chromium alloy (MP35N, L605)
1. Excellent Biocompatibility: Non-cytotoxic, immune rejection-free, compliant with ISO 10993 medical standards.
2. Excellent electrical performance: It is an ideal electrode material, commonly used in deep brain stimulation (DBS) electrode cannulas.
3. Excellent Corrosion Resistance: Possesses exceptional resistance to body fluids and blood corrosion, with no risk of excessive metal ion release during long-term implantation.
4. It exhibits extremely high strength, with a tensile strength of up to 1900-2200 MPa. Even in thin-walled conditions, it remains resistant to deformation and possesses fatigue resistance, making it suitable for structures requiring stable support.
Stainless Steel (SS304, 304V, 316L, 316LV, etc.)
1. Mature mechanical properties and cost advantages, suitable for various structural components.
2. Precision Customization: Dimensions (diameter, wall thickness) can be flexibly customized according to customer requirements.
3. High Reliability: Provides the foundation for the stability and safety of high-end medical devices.
