That’s because titanium is an active element, and a thin layer of TiO2 oxide film can be formed on the surface of the material at the moment of exposure to air. This oxide film has a high degree of inertness and can limit further oxidation and corrosion. , to ensure good biocompatibility of titanium; in terms of mechanical properties, titanium has low density, high mechanical strength, and elastic modulus closer to bone tissue than other medical metals, which means that titanium has ideal biomechanical compatibility In addition, it also has good machinability and is easy to process and shape.
In recent years, the application of titanium alloy screw fasteners is extremely extensive, among which titanium alloy screws are more and more widely recognized by the market because of their obvious advantages, such as high strength, single body, single-sided assembly connection, and reusable etc. With the world’s industrial technology and social progress, titanium alloy screws will have a greater development and wider use.
Therefore, the advantages of titanium alloy screws have the following aspects
1. High specific strength. The density of titanium is 4.51g/cm², which is higher than aluminum but lower than steel, copper and nickel, but its strength is much higher than other metals. Screws made of titanium alloy are light and strong.
2. Good corrosion resistance. Titanium and titanium alloys are stable in many media, and titanium alloy screws are suitable for various corrosive environments.
3. Good heat resistance and low temperature resistance. Titanium alloy screws can work normally in a high temperature of 600°C and a low temperature of minus 250°C, and can maintain their shape without changing.
4. Non-magnetic and non-toxic. Titanium is a non-magnetic metal, and it will not be magnetized in a large magnetic field; it is not only non-toxic, but also has good compatibility with the human body.
5. Strong damping resistance. After titanium is subjected to mechanical vibration and electrical vibration, compared with steel and copper metals, its own vibration attenuation time is the longest. Utilizing this performance, it can be used as a tuning fork, a vibrating element of an ultrasonic pulverizer in medicine, and a vibrating film of a high-end audio speaker.
With the development of titanium industry, titanium alloy screws will no longer be limited to high-end precision industries, but will go deeper into people’s daily life, so the development space of titanium alloy screws has a bright future, and the future can be expected!
