The advantages of fasteners mainly include the following aspects:
Lightweight and high specific strength: Titanium alloy fasteners have a lower density than steel materials and have a higher specific strength. They can be used in smaller sizes under the same load, saving space, and are particularly suitable for the aerospace field.
Heat resistance and corrosion resistance: Titanium alloys can still maintain good mechanical properties at high temperatures and are suitable for high temperature environments. In addition, titanium alloys perform well in a variety of corrosive media and are suitable for marine engineering and chemical industries.
High yield strength ratio and anti-magnetism: Titanium alloys have high yield strength and are suitable for bearing tensile loads. At the same time, titanium alloys are almost non-magnetic and are suitable for precision machinery that needs to avoid magnetic field interference.
Excellent thermal fatigue performance: Due to the small thermal expansion coefficient and elastic modulus of titanium alloys, the thermal stress generated when the temperature changes is small, and it has excellent thermal fatigue performance.
Potential matching and creep resistance: The electrode potential of titanium alloys matches that of carbon fiber composites, effectively preventing galvanic corrosion. In addition, titanium alloy has strong creep resistance and is suitable for long-term load-bearing situations.
Environmental protection and economy: The use of titanium alloy fasteners can significantly reduce mechanical mass and energy consumption, and has significant environmental and economic advantages.
