Titanium is close to human bones, and has good biocompatibility and no side-effects on human tissues. Human implant is a special functional material closely related to human life and health. Compared with other metal materials, the advantages of using titanium and titanium alloy are mainly as follows:
① light weight. ② low modulus of elasticity. ③ non-magnetic. ④ non-toxic. ⑤ Corrosion resistance. ⑥ High strength and good toughness.
The use of titanium in surgical implants is growing at a rate of 5 to 7 percent per year. Using titanium and titanium alloy manufacture of femoral head, hip, humerus, skull, knee, elbow, shoulder joint, joint, jaw and heart valves, kidney distinguishes the membrane, blood vessel expander, plywood, prosthesis, fastening screws and other hundreds of transplanted into the body of the metal, has obtained the good effect, gave a high evaluation by the medical profession.
2. Titanium is widely used in daily life.
It can be said that it is everywhere, such as golf ball head, bicycle frame, tennis racket, wheelchair, glasses frame and so on.
3. Titanium has been used in racing cars for many years.
The preferred way of automobile lightweight is to use lightweight materials with high specific strength, such as aluminum, magnesium, titanium, etc., to replace the traditional automobile materials (steel). In 2019, the amount of titanium used in the global automobile has reached 3000 tons. Titanium has been used in racing cars for many years. At present, almost all racing cars use titanium material. The titanium used in Japanese cars has exceeded 600 tons.
4. Titanium is widely used in the manufacture of aerospace equipment.
Titanium in aerospace is mainly used in western countries, especially the United States, where 60% of titanium is used in this field. Asian countries, Japan and China each invest around 10% of their titanium in this field. However, with the rapid development of Aerospace in Asia in recent years, the consumption of titanium in aerospace will increase accordingly.
5. Titanium alloy is an important structural material for Marine equipment.
Titanium alloy is an important structural material for Marine equipment such as ships, submarines and manned deep submersible, which is known as "ocean metal". The United States, Russia and other military powers have applied a large amount of titanium in their advanced ships and submarines, and the amount of titanium is gradually increasing. The increment of titanium in deep sea mainly lies in the projects of deep sea space station, deep submarine and submarine, etc., which is characterized by the large amount of titanium used in a single project, but the project's promotion time is relatively long. At present, the research and development of the project is progressing steadily, but the demand for large volume still needs to wait.
