The medical quality Ti-6AL-7Nb titanium rod is a kind of top implant material that is oriented to application in the medical industry. It removes the potentially cytotoxic element vanadium present in Ti-6AL-4V titanium alloy and substitutes it with niobium, which provides for a step up in biocompatibility and tissue affinity, finding itself as the best material for both orthopaedic and dental implant surgeries. The titanium rod of this kind is precision forged and precision heat treated letting to keep a high strength level and still having a remarkably toughness so that it can be perfectly fitted with a complex mechanical environment of human body without suffering from various risks like breaking or loosening after it is implanted. It is a standard material of orthopedic joint replacement components, extended to diameter from 8-50mm and length from 500-3000mm, can be directly machinined into core components such as hip joint stem and knee joint condyles at present. In the dental implant industry, some smaller specification titanium rods (with a size of 3-8mm in diameter and a size of 10-150mm in length) are utilized for different tooth positions.

Comparison with Ti-6Al-4V Eli
| Material | Ti-6AL-7Nb | Ti-6AL-4V Eli |
| βStabilizer | Nb (Niobium metal) | V(Vanadium Metal) |
| Biocompatibility | good, non-toxic and non-irritating | In the experiment, there was controversy over toxicity |
| Mechanical properties | Same | Same |
| Risks of medical use | There is a risk of vanadium ion release in the material | Almost no risk of metal ion release |
| Price | Because it contains niobium metal, the price is higher than Ti-6Al-4V Eli | Slightly higher than alloy Ti-6Al-4V |
The key features of Ti-6AL-7Nb titanium rods are its unique composition and well-rounded properties. Niobium improves the corrosion resistance of the alloy, preventing ion release in the biological fluid environment of the human body and decreases the elastic modulus of the material making it more similar to the elasticity of the human bone. This significantly reduces the "stress shielding effect" and leads to healing and growth of the bone tissue.
In spinal internal fixation surgeries, these titanium rods can be machined into connecting rods with diameters ranging from 4.5 to 10mm, working in conjunction with a screw system to achieve spinal reduction and fixation. Their excellent X-ray transparency allows doctors to clearly observe postoperative bone healing.
They have more than 40 % higher tensile and yield strength than pure titanium with the yield strength above 860MPa, which could make their performance stable under the load of daily human activities. They also show less cytotoxicity compared to Ti-6Al-4V ELI, thus presenting higher potential for use in long term implantation in the human body.
As a professional medical grade titanium rod manufacturer, we have three advantages that can guarantee the quality of our products and service.
First, our comprehensive quality control system spans the entire production process. Starting with the selection of sponge titanium raw materials, we employ vacuum arc remelting furnaces for three-stage smelting to guarantee uniform composition. Subsequent rolling and heat treatment processes are equipped with imported German inspection equipment, enabling 100% full testing of mechanical properties and metallographic structures.
Second, we have the high flexibility for customization to meet different requirements. We provide titanium rods with the diameter of 2 to 100mm and the length of 100 to 6000mm, and accept custom processing such as tapering, chamfering and surface polishing(Ra0 . 2-Ra1 .For specialized surgical instrument requirements, we also provide precise composition adjustments and performance optimization solutions, with a minimum custom lead time of just 7 working days.
Finally, we maintain full compliance with global standards, with products certified under ISO 13485 Medical Device Quality Management System, FDA registration, and CE certification. Each batch includes complete material certificates and traceability reports, ensuring compliance with the entry requirements of major global medical markets.
