Titanium alloy screws are widely used in many parts of aircraft, mainly because of their excellent strength-to-weight ratio and corrosion resistance.

1. Fuselage structure: Titanium alloy screws can be used for connecting parts of the aircraft fuselage to provide strength and durability.

2. Wing: In the wing structure and ancillary components, titanium alloy screws are commonly used to connect the structure between the wing and the fuselage.

3. Engine: Titanium alloy screws can be used to fix engine components, including turbine and compressor components.

4. Landing gear: In the landing gear system, titanium alloy screws can be used to connect and load-bearing components.

5. Internal equipment: such as the fixation of seats, bulkheads and other equipment in the cabin.

Due to the high temperature resistance and corrosion resistance characteristics of titanium alloy, it is particularly suitable for the demanding environment in the aviation field.
