Why is titanium used in aircraft?
Titanium has been replacing aluminum parts in aircraft manufacturing because of its ability to resist heat and corrosion when it comes in contact with carbon-fiber reinforced polymers (CFRPs). Titanium is now used in the fastening elements, airframe and landing gear of airplanes.
Titanium is an important structural metal widely used in the aerospace field. The specific strength of titanium is the highest among commonly used metal materials, so it was quickly used in the aviation industry. The aviation industry has always been the largest user of titanium in the world market for 50 years. The figure below shows the main parts and components of titanium and titanium alloy used in aircraft.
