Titanium is an important structural titanium plates metal in the 1950s developed, titanium because of its high strength, good corrosion resistance, and high heat resistance, it is widely used in various fields. Many countries recognize the importance of titanium alloy, have their research and development, and has been applied. 1950s and 1960s, mainly in the developing of high temperature titanium and titanium alloy airframe of the aircraft engine, developed in the 1970s a number of corrosion resistant alloy, since the 1980s, corrosion resistant titanium rods and high-strength titanium alloy further development of.
