Titanium has very good properties, so it is widely used. Its main application fields are: aerospace, shipbuilding, chemical and petrochemical, transportation, weapons, marine, electric power, construction, metallurgy, medical treatment, sports equipment, daily necessities and light industry. Most of the titanium processing materials in the United States and Russia are used in the aerospace field, accounting for about 80%, while Japan and China are used in the fields of chemicals, general civil industry and civilian products. From the perspective of the world's demand for titanium, the structural proportion in 2005 was: aerospace accounted for 35%, military accounted for 12%, industrial accounted for 38%, civilian and other accounted for 15%.
In the weapons industry, titanium is used in: tanks, combat vehicles, missiles, large and small artillery shells, machine guns, flamethrowers, helmets, body armor, explosion-proof gloves, etc.
In the metallurgical industry, titanium is used in: corrosion-resistant vessels, electrolyzers, reactors, concentrators, separators, heat exchangers, coolers, pumps and valves, turbine blades, connecting piping, fittings, etc.
The aviation industry was the earliest sector in the development and application of titanium and titanium alloys, and without titanium for aircraft and engines, it would practically be impossible to create a supersonic aircraft of the Ma2.7. Titanium alloy is mainly used in aircraft structure for skeletons, skins, fuselage bulkheads, landing gear, fire walls, wings, tails, longitudinal beams, hatch covers, multipliers, keels, snap-action brake brakes, shutdown devices, fasteners, front wheels, arch frames, flap slide rails, composite plates, road sign lights and signal boards, etc.
The application of titanium in the aerospace industry has also reduced the launch weight, increased the range and saved the cost, and is a popular material in the aerospace industry. In the rocket, missile and aerospace industries, it can be used as pressure vessels, fuel tanks, rocket engine shells, rocket nozzle casings, artificial satellite shells, manned spacecraft cabins (skin and structural skeletons), landing gear, lunar modules, propulsion systems, etc. In addition to industrial pure titanium Ti64 (ELI) and Ti-5Al-2.5Sn (ELI), Ti-7Al-4Mo, Ti-3Al-2.5V, Ti-13V11Cr-3Al, Ti-15V-3Cr-3Sn-3Al and Ti/B-Al composites are also used for aerospace titanium.
Titanium and titanium alloys are widely used in nuclear submarines, deep submersibles, atomic icebreakers, hydrofoils, hovercraft, minesweepers, as well as propeller thrusters, whip antennas, seawater pipelines, condensers, heat exchangers, acoustic devices, fire-fighting equipment, the main alloys are industrial pure titanium, Ti64, Ti64ELI, Ti-6Al-2Nb-1Ta-0.8Mo, Ti-3Al2.5V, IIT-3B, IIT-7M, etc.
Titanium is used in the chemical and petrochemical industries, including electrolyzers (electrodes), reactors, concentrators, separators, heat exchangers, coolers, absorption towers, connecting piping, fittings (flanges, bolts, nuts), gaskets, pumps, valves, etc. The largest amount of titanium used in the chemical industry is chlor-alkali manufacturing, accounting for 50% of the total titanium consumption, followed by soda ash accounting for 20%, plastics accounting for 17%, organic chemicals accounting for 10%, and inorganic chemicals accounting for 3%. Among the various chemical equipment that uses titanium, heat exchangers are the most, accounting for 52% of the amount of titanium, followed by anodes accounting for 24%, containers, pipes and pump valves accounting for 19%, and others accounting for 5%. The following uses heat exchangers, titanium anodes, and wet chlorine gas coolers as examples to illustrate the advantages of titanium equipment.
