Titanium legeringblev udviklet med succes i 1950'erne. På grund af dens høje styrke, gode korrosionsbestandighed, høje varmebestandighed og lyskvalitet er den blevet meget brugt på forskellige områder. Titanium blev først brugt på det militære område i de store militærmagter som USA og Rusland.
The U.S. Air Force secretly developed the All-Titanium Airplane SR-71 Black Bird in 1959. Its titanium alloy usage accounted for 93 percent of the airframe's weight, which enabled the airplane to successfully break through the heat barrier and fly at three times the speed of sound while maintaining the airframe's strength. The prestigious F-22 and F-35 stealth fighters use Ti extensively in their body materials and engines, which makes the F-22 and F-35 superior in performance.
Titaniumlegering er også meget brugt i flåden på grund af dens korrosionsbestandighed og høje styrkeegenskaber. Under den kolde krig brugte det tidligere Sovjetunionen en stor mængde aftitanlegering materials for submarine hulls, such as the well-known "Alpha" nuclear submarine, which was the first submarine in the Soviet Navy to use titanium alloy materials to construct heat-resistant hulls. The depth of the submarine can reach 700 meters, making it a "big killer" that frightens Western countries.
With the rapid development of China's military industry, many achievements have been made in the military field. The most advanced fighter-20 stealth fighter Made in China uses titanlegering beams, which are extremely difficult to process so that the fighter-20 body has an incomparable high strength. It is believed that in the near future, better titanium materials and advanced technology will be applied in China's military industry one after another, creating better performance weapons and equipment, and enhancing the fighting capacity of the People's Army.
