Why are titanium alloy screws so popular?
That's because titanium is an active element, and a thin TiO2 oxide film can be formed on the surface of the material at the moment of exposure to air. This oxide film is highly inert and can limit further oxidation and corrosion. , to ensure the good biocompatibility of titanium; in terms of mechanical properties, titanium has low density, high mechanical strength, and elastic modulus is closer to bone tissue than other medical metals, which means that titanium has ideal biomechanical compatibility. In addition, it also has good machinability, which is easy to process and form.
In recent years, the application of titanium alloy screw fasteners is extremely extensive. Among them, titanium alloy screws are more and more widely recognized by the market because of their obvious advantages. They have high strength, single body, single-sided assembly connection, and reusability. etc., with the progress of world industrial technology and society, 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/cm³, which is higher than that of aluminum but lower than that of steel, copper and nickel, but its strength is much higher than that of other metals. The 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 can be used in various corrosive environments.
3. Good heat resistance and low temperature resistance. Titanium alloy screws can work normally in a high temperature environment of 600 ° C and a low temperature of minus 250 ° C, and can maintain their own shape without changing.
4. Non-magnetic and non-toxic. Titanium is a non-magnetic metal and 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 anti-damping performance. After titanium is subjected to mechanical vibration and electrical vibration, its own vibration attenuation time is the longest compared with steel and copper metals. Using this property, it can be used as a tuning fork, a vibration element for a medical ultrasonic mill, and a vibration film for an advanced audio speaker.
With the development of the titanium industry, titanium alloy screws will no longer be limited to high-end precision industries, but more deeply into people's daily life, so the development space of titanium alloy screws has a bright future, and the future can be expected!
