Advantages And Applications Of Titanium Alloy Screws

Sep 21, 2020

In recent years, the application of titanium alloy screws has become more and more extensive. Although the price of titanium alloy screws has always been higher than that of screws of other materials for models of the same specification, its performance and application range have the irreplaceable advantages of ordinary screws.

Advantages of titanium alloy screws

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 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 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 will not be magnetized in a large magnetic field; it is not only non-toxic, but also compatible with the human body.

5. Strong anti-damping performance. Titanium has the longest vibration decay time compared with steel and copper after being subjected to mechanical vibration and electrical vibration. Using this performance, it can be used as a tuning fork, medical ultrasonic pulverizer vibrating element, and high-end audio speaker vibrating film.

Application of titanium alloy screws

Relatively expensive metal materials like titanium alloys are mainly used in some high-end precision industries.

1. The nuclear industry

During the construction of nuclear reactors, many parts, pipelines and related parts require a large amount of titanium and titanium alloy metals, and titanium alloy screws are one of them.

2. Electronic equipment

In the past, many mobile phones and computers used steel screws. However, the steel is magnetic and needs to be demagnetized, otherwise the steel screws are easily magnetized under the influence of electromagnetic fields, which will affect the network signal. Titanium alloy screws are non-magnetic, light in weight and high in strength, making them very suitable for use as fasteners for electronic equipment.

3. Medical industry

Titanium is a biophilic metal and is widely used in the medical industry. Titanium alloy screws are often used for the fixation and treatment of clinical fractures and dislocations. They are strong and not easily deformed.

4. Aerospace

The aerospace industry is still the most important titanium user. Using titanium alloy screws to replace steel screws with similar strength has a significant effect on aircraft weight reduction. In addition, titanium alloys have good elasticity and non-magnetic properties, which also play a very important role in preventing screw loosening and preventing magnetic field interference.

With the development of the titanium industry, titanium alloy screws will no longer be limited to high-end precision industries, but will go deeper into people's daily lives.
