Among medical metal materials, titanium and titanium alloys have become the preferred materials for medical implant products such as artificial joints (hip, knee, shoulder, ankle, elbow, wrist, knuckles, etc.), bone trauma products (intramedullary nails, plates, screws, etc.), spinal orthopedic fixation systems, dental implants, brackets, orthopedic wires, artificial heart valves, interventional cardiovascular stents, etc. due to their excellent comprehensive properties.
The titanium materials specified for use in surgical transplant materials are mainly pure titanium and Ti-6Al-4VELI alloy.

Peakrise Metal TC4 high-precision medical titanium rod technical features: low gap TC4 and TC4 two standards in one, that is, it has the low impurities of low gap TC4 ELI and the high performance of TC4. That is to say, it has the performance characteristics of high strength and high plasticity at the same time. The following is a specific comparison of them:

Using titanium rods to make artificial bones, cells can regenerate on them and bones can grow. Titanium has good affinity with human bones, epithelium, and artificial tissue. In order to improve the surface quality of implants connected to human bones, applying a bioceramic layer to the roughened surface is also a more effective method.
φ6, φ7, φ8, φ10, φ12, φ14 are all in stock year-round.
φ10 and below can be used as bone screws, φ12 and 14 can be used as cone-arch screws, φ16 and 17 can be used as intramedullary nails, and φ20-40 can be used as prosthetic accessories.
