Titanium has a wide range of applications in the
medical field. Titanium is close to human bones and has good bio compatibility to
human tissues without toxic side effects. Human implants are special functional materials closely related to human life and
health. Compared with other metal materials, the main advantages of using titanium and titanium alloys are as follows: light
weight, low elastic modulus, non-magnetic, non-toxic, corrosion resistance, high strength and good toughness. The amount of
titanium alloy used in surgical implants is increasing at an annual rate of 5%-7%. Femoral heads, hip joints, humerus, skull,
prostheses, made of titanium Hundreds of metal parts, have been transplanted into the human body, which has achieved good results
and has been highly praised by the medical community.
