Introduction of Small Diameter Titanium Rod For Medical
Small Diameter Titanium Rod For Medical refer to medical-grade titanium and titanium alloy rods with a diameter of ≤25mm. They primarily adhere to the international standard ISO 5832 and are characterized by high precision, high biocompatibility, and ease of shaping and processing. They serve as the core base material for miniature implants in fields such as dentistry, minimally invasive orthopedics, and neurosurgery.
It possesses excellent biocompatibility, mechanical adaptability, and resistance to body fluid corrosion, making it a core base material for implantable devices in orthopedics, dentistry, neurosurgery, and other fields.
The core value of Small Diameter Titanium Rod For Medical lies in their compatibility with the human physiological environment, requiring them to simultaneously meet three key requirements: biocompatibility, mechanical matching, and processability.

Key performance requirements for Small Diameter Titanium Rod For Medical (medical implant rigid specifications)
1. Biocompatibility
Cytotoxicity: ≤ Grade 1 (ISO 10993-5), no apoptosis;
Sensitization/Irritation: No sensitization reaction, skin irritation score 0;
Hemolysis rate: ≤5% (ISO 10993-4), no risk of hemolysis.
2. Dimensions and Surface Accuracy
Diameter tolerance: ±0.001mm for φ≤3mm, ±0.002mm for φ3~10mm;
Surface quality: No scratches, pits, or grinding burns under 10x magnification, no residual grinding debris;
No residual stress: Low-temperature stress relief annealing (150℃×1h) to prevent deformation caused by stress release after implantation.
3. Resistance to Body Fluid Corrosion
Simulated body fluid immersion test (37℃ Hank's solution, 72h), corrosion rate ≤0.0005mm/year, no pitting or rusting on the surface, no metal ion precipitation.
