Ti | Balance |
1. High specific strength. The density of titanium is 4.51g/cm³, 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.
