Medical Grade Titanium Alloy Rod

Medical-grade titanium alloy rods are the core implant base materials that integrate biomedical and materials engineering technologies. They are widely used in key medical fields such as artificial joint prostheses, spinal fixation systems, dental implant abutments, and cardiovascular interventional devices. Leveraging precise titanium alloy material control technology, our medical-grade titanium alloy rods strictly adhere to the stringent standards for medical implant materials. From raw material smelting to final product delivery, the entire process undergoes biocompatibility management. We provide high-quality materials with both clinical reliability and processing adaptability to global medical device manufacturers, helping to enhance the performance of implant devices and improve patient rehabilitation outcomes.

In terms of dimensional parameters, we focus on multi-scenario adaptability to provide customized solutions. The diameter ranges from 1.2mm to 150mm, and the length can be flexibly customized based on customer production requirements, with a standard supply range of 200mm to 6000mm. The tolerance precision is consistently controlled within ±0.015mm, far exceeding the standards of ordinary industrial titanium rods. The rod straightness is ≤0.2mm/m, and the surface undergoes multi-stage precision polishing, with roughness adjustable to Ra0.2μm-Ra1.6μm as needed. This meets the fine requirements of minimally invasive implant devices while also accommodating the machining needs of large load-bearing joints, fully complying with international medical material dimensional standards such as ASTM F136 and ISO 5832-3.

The series is tailored toward optimization of processing performance for medical use and is comprised of four basic series: Ti-6Al-4V ELI (GR5), Ti-6Al-7Nb (GR23), Ti-13Nb-13Zr and Ti-5Ta. Ti-6Al-4V ELI as a traditional grade improves fatigue strength with the control of the interstitial elements at ultra-low level, so it can be used for load bearing parts such as artificial hip and knees joint. Ti-6Al-7Nb substitutes niobium for vanadium to eliminate hazards of cytotoxicity and is considered the best option for dental implants and pediatric orthopedic tools. Ti-13Nb-13Zr has a more bone-like elastic modulus than other materials, which reduces stress shielding and is recommended for spinal internal fixation rods. Ti-5Ta is known for its superior body fluid corrosion resistance for use in continuously long-term residing devices such as cardiovascular stents.

The core benefits can be seen in 3 aspects when compared with conventional medical materials:

1. High Biocompatibility: Has received biological evaluation under ISO 13485 series, no sensitization or hemolysis was observed. The surface oxide film acts as a permanent biologic barrier.

2. Exact Mechanical Strength Matching: Due to the adjustment of alloying element ratio, it can achieve high strength over 860MPa and suitable toughness, thus decreasing the chance of fracture after implantation.

3. Suitable for Complex Forming and Sterilization: It's suitable for complicated procedures like laser cutting and 3D printing, and it supports different sterilizing techniques like temperature and moisture, as well as gamma ray irradiation, and also its performance is stable even when sterilized for multiple times.

We reserve a full line quality control system from traceability of raw material to the inspection of finished products. Our products are ISO 13485 and CE MDR certified and for each batch is provided a full material analysis report and biocompatibility test report. For the international customers, we support customized surface treatment, special size processing and multi-languages technical documents. Through our global warehousing and distribution network, we provide quick supply to regions such as Europe, America, Southeast Asia, to assist our clients in capturing the opportunities of international medical device market.
