Why titanium screws are more expensive than other screws


Do you know why the price of titanium alloy screws is always higher than that of other screws of the same specification? The reason is closely related to the performance and application of titanium. The advantages of titanium screws are mainly reflected in the following aspects:

1. High specific strength. The density of titanium is 4.51g/cm ³, which is higher than that of aluminum and lower than that of steel, copper and nickel, but its strength is much higher than that of other metals. So screws made of titanium alloy are not only light but also strong.

2. Good corrosion resistance. Titanium and titanium alloys are stable in many media, and titanium alloy screws are suitable for a variety of corrosive environments.

3. Good heat resistance and low temperature resistance. Titanium Alloy Screw can work normally at high temperature of 600 ℃ and low temperature of minus 250 ℃, and can keep its shape unchanged.

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. Compared with steel and copper metal, titanium has the longest vibration attenuation time after being subjected to mechanical vibration and electrical vibration. This performance can be used as vibrating film for tuning forks, medical ultrasonic crusher vibration components and advanced audio loudspeakers.

Relatively expensive metal materials such as titanium alloy are mainly used in high-end precision industries such as nuclear industry, electronic equipment, medical industry, aerospace and so on. However, 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.
