During the construction of nuclear reactors, many parts, pipes and related parts require a large amount of titanium and titanium alloy metals. Titanium alloy screws are one of them.
In the past, many mobile phones and computers used steel screws. However, steel is magnetic and needs to be degaussed. Otherwise, steel screws are easily magnetized by the electromagnetic field and affect network signals. Titanium screws are non-magnetic, lightweight and strong, making them ideal for electronic device fasteners.
Titanium is a biophilic metal that is widely used in the medical industry. Titanium alloy screws are often used in the fixation and treatment of clinical fracture and dislocation. They are strong and not easily deformed.

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.
