Description
🔬 Introduction
Our tantalum medical screws are engineered from ultra-high-purity tantalum (≥99.95%) to meet the stringent demands of surgical and biomedical implantation. These screws conform to ASTM B365 and are specifically designed for long-term use in orthopedic fixation, craniofacial surgery, and dental implant systems.
Tantalum’s unique material characteristics—non-reactivity, exceptional corrosion resistance, and complete biocompatibility—make it the preferred choice for applications where implant performance and longevity are critical. These tantalum medical screws offer unmatched tissue compatibility and structural integrity, outperforming titanium in certain niche applications.
🧪 Key Material Properties
All tantalum medical screws are produced using advanced powder metallurgy or forged bar stock derived from vacuum-arc remelted tantalum ingots. They are subjected to precise dimensional control and surface finishing to ensure superior clinical results.
| Property | Value |
|---|---|
| Purity | ≥99.95% Tantalum |
| Melting Point | 3017°C |
| Density | 16.65 g/cm³ |
| Elastic Modulus | 186 GPa |
| Magnetic Properties | Non-magnetic |
| Corrosion Resistance | Superior in chloride-rich environments |
These material properties ensure that tantalum medical screws remain chemically stable in the body and maintain their structural performance over time.
⚙️ Product Features
- Material: 99.95% pure tantalum
- Standard: ASTM B365 compliant
- Head Types: Pan, Torx, hex socket, countersunk
- Thread Configurations: Metric, UNC, self-tapping
- Surface Options: Polished, passivated, or sandblasted for enhanced osseointegration

These tantalum medical screws are available in both standard orthopedic dimensions and fully custom-machined variants for OEM applications.
🏥 Medical Applications
Tantalum medical screws are widely used in:
- Orthopedic trauma repair – especially in regions prone to post-operative sensitivity
- Dental implant platforms – for long-term osseointegrated abutments
- Spine and craniofacial surgery – where superior biocompatibility is essential
- Maxillofacial reconstruction – including pediatric implant devices
- Cases involving titanium allergies – providing a biologically inert alternative
Their long-term tolerance in bone and soft tissue has been confirmed in numerous clinical studies, validating the reliability of tantalum medical screws for permanent or semi-permanent use.

🌐 Export Compliance
Although tantalum screws are not classified as dual-use items, they are subject to export license approval under Chinese customs law due to their implantable medical nature. All international buyers must prepare the following documents:
- End User Statement (EUS) – must clearly state the intended non-military medical use
- Company Certificate / Import License – for institutional buyers
- Purchase Order & Contract Copy – for customs documentation
⏳ Estimated License Processing Time: ~25–30 calendar days
Note: The export license requirement applies even for small volumes or prototypes. Failure to obtain proper clearance may result in shipment delays or seizure.
