The mechanical properties of medical titanium rods comply with GB/T13810-2007 and ASTM F67/F136.
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.
