Ti6AL4V Eli is a special titanium grade and it is an important branch of medical material, Titanium rod for medical , which is a new carrier material with high technological content and economic value used for diagnosis, treatment, or replacement of human tissues, organs, or enhancement of their functions. It is a developing new field in materials science and technology. Medical Grade 23 titanium rods make greater contributions to exploring the mysteries of human life and ensuring human health and longevity.

In medical metal materials, titanium alloys have become the preferred materials for medical implant products such as artificial joints (hip, knee, shoulder, ankle, elbow, wrist, finger joints, etc.), bone trauma products (intramedullary nails, steel plates, screws, etc.), spinal corrective internal fixation systems, dental implants, dentures, orthodontic wires, artificial heart valves, interventional cardiovascular stents, etc., due to their excellent comprehensive performance.

Using Ti6AL4V Eli titanium bars to create artificial bones, cells can regenerate on it, bones can grow, and titanium has good affinity with human bone, epithelium, and tissue. In order to improve the surface quality of implant materials connected to human bones, applying a bioceramic layer to the roughened surface is also an effective method.

The medical Ti6AL4V Eli titanium rods of Baoji Yutong Metal Materials Co., Ltd. are made of grade 0 sponge titanium and strictly processed according to ASTM F136. After multiple high-temperature pier drawing and forging, the rod billets are hot-rolled to the required size, machined, drawn, heat treated, straightened, polished, and subjected to non-destructive testing. The finished rod material is then polished. The Ti6AL4V Eli rod has good biocompatibility, good corrosion resistance, high strength, and is widely used in clinical practice.
