The advantages of medical titanium

Human implants are unique functional materials that are closely related to human life and health. Compared with other metal materials, the advantages of using titanium and titanium alloy have six main points:

1 light weight

The density of titanium and titanium alloys is 4.5g / cm 3 at 20 C and only 56% of that of stainless steel. Implanted in the body significantly reduce the body's load, as a medical device also lightened the workload of medical staff.

2 low modulus of elasticity

Low elastic modulus of titanium and titanium alloy, titanium is 10850 kg / mm 2, only 53% of stainless steel,

Implantation of human body closer to the natural bone, is conducive to bone. Bone can reduce the stress shielding effect of implants.

3 non-magnetic

Titanium and titanium alloys are non-magnetic metal that is unaffected by electromagnetic fields and thunderstorms, which are good for human safety after use.

4 non-toxic

Titanium and titanium alloy non-toxic, as an implant without toxic side effects on the human body. .

5 corrosion resistance

Titanium and titanium alloy is known as a bio-inert metal material, has excellent corrosion resistance to human blood immersion environment to ensure good compatibility with human blood and tissue, as an implant does not produce human pollution, No allergic reaction, which is the basic conditions for the application of titanium and titanium alloys.

In the human implant titanium and titanium alloy surface anodizing coloring treatment to improve the implant in the human body conditions, wear resistance, corrosion resistance and fatigue resistance cycle, but also to a large extent solved the dissolution of metal ions Problem, improve the compatibility of implants. At the same time can be used as a logo of different specifications of products to facilitate the operation.

6 high strength, good toughness

Due to trauma, cancer and other factors lead to bone and joint damage, in order to establish a solid bone scaffold, must use arc plates, screws, artificial bone and joints, etc. These implants should be placed in the human body for a long time, will be subject to human body bending, Torsion, extrusion, muscle contraction and other effects, require implants with high strength and toughness. Research and clinical examples prove that pure titanium can be used in the places where human body stress is small and the Ti-6Al-4V alloy can be used in places where human body stress is large, which can fully meet the requirements of human implants.

Titanium and titanium alloys have excellent serviceability and are universally recognized as superb metallic materials in the field of biomedical applications. Compared with the use of metallic materials such as stainless steel and cobalt-based alloys, titanium and titanium alloys have great application advantages and vast room for development.
