Titanium has a very broad application in the military industry. Nuclear power submarines, hydrofoil boats, mortar barrels, anti-tank missiles, missile launchers, tank shields, and bullet-proof vests use a large amount of titanium. According to information, a typhoon-class nuclear submarine uses up to 9,000 tons of titanium, which shows that the military has a huge demand for titanium.
Titanium is widely used in the aviation industry. The amount of titanium used in civil aircraft accounts for about 20-25% of the weight of the framework. In addition, titanium is also widely used in strategic rocket engines, spacecraft (such as Shenzhou 5 and Shenzhou 6), and satellite antennas.
- Marine industry applications
In seawater, titanium has corrosion resistance unmatched by other metal materials, especially the high-speed erosion corrosion of seawater. At present, the United States, Japan, France and other countries have developed a variety of advanced titanium deep submersibles, submarines, subsea laboratory equipment for marine research. In addition, titanium equipment and devices are widely used in coastal power stations, offshore oil production equipment, seawater desalination, marine chemical production, and marine aquaculture.
- Application in chemical industry
At present, the application of titanium equipment has expanded from the original “soda and caustic soda industries” to the entire chemical industry, and the types of equipment have developed from small and unitary to large and diverse. According to the prediction of the chemical sector, the annual amount of titanium used in the chemical industry will exceed 1,500 tons. After the 1970s to 1980s, China’s vacuum salt manufacturing enterprises gradually began to use titanium metal materials to manufacture equipment, and as a result, the equipment corrosion situation has greatly improved.
