J-20 titanium alloy ratio of up to 20%

- Sep 25, 2017-

The use of new materials to measure the technical content of aircraft, domestic aircraft disclosed little data. However, in August held in 2017 summer academician expert series of popular science forum, the famous Chinese aviation material scientist, Chinese Academy of Sciences Cao Chunxiao rare rare, annihilated as the representative of the four generations of machine, the body structure of titanium alloy and composite Material ratio has made great progress.

Titanium alloy is a high strength, good corrosion resistance, high heat resistance of the alloy material, the last century 50's began to use in the combat aircraft, this alloy is more expensive than gold metal, especially due to the titanium alloy in the welding And other processing technology there is a great difficulty, which is generally used only for combat aircraft and other high-tech defense weapons, the world's most experienced titanium processing experience in Russia also use it to build nuclear submarines, called "goldfish."
