Titanium alloy, excellent performance, at the beginning of the development mainly used in the military field, and the military field is very high material requirements, because the operating environment of equipment such as fighter jets is very demanding.
Pure titanium has the highest strength-to-weight ratio of any metal on earth. It is as strong as steel, but 45 percent lighter. At present, titanium alloy products, mainly used in aircraft engines, aircraft fuselage, rockets and so on. The airbus A380, the world's largest passenger jet, contains 70 tonnes of titanium, which is used mainly in engines. In submarines, is also very versatile, such as Russia's famous "typhoon" class nuclear submarine, a large number of titanium alloy. Of course, although the use of titanium alloy can reduce the weight of the body, but the cost is relatively high.
And titanium products, will not appear such a problem, do not need us to apply a layer of antirust agent for it alone. Because the surface of titanium is covered with a thin layer of titanium dioxide (TiO2), it can actually protect the underlying titanium from any type of corrosion, including electrochemical, microbial, and stress corrosion.
Due to this feature, make titanium alloy products, is a good way to play a role in all kinds of high corrosion environment, as previously mentioned the submarines, perennial soak in water for submarines and other naval vessels, and the water is rich in all kinds of ions, corrosion resistance is strong, general metal products will soon be corrosion, the titanium alloy was don't have to worry about the problem.
