3. Application fields:
1. Aerospace field
The application of titanium in the aviation industry is mainly used as key structures such as compressor discs, blades, wings, and skins of engines. In civil airliners, it is mainly used as structural frames such as the fuselage beam, middle section, and inner arm plate. It mainly uses its low density, high strength, high temperature resistance, and corrosion resistance. It also achieves the purpose of reducing launch mass, increasing range, and saving costs. It is a popular material in the aerospace industry. In rockets, missiles, and the aerospace industry, it can be used as pressure vessels, fuel tanks, rocket engine casings, rocket nozzle sleeves, artificial satellite casings, manned spacecraft cabins (skins and structural skeletons), landing gear, lunar modules, propulsion systems, etc.
2. Medical field
Titanium and its alloys are non-toxic, lightweight, high specific strength, resistant to biological corrosion and good biocompatibility. They are ideal medical metal materials and are widely used in artificial bones, artificial joints, dentistry, plastic surgery, cardiac surgery, internal support frames and medical devices in the medical field.
3. Military field
Titanium is widely used in the military field, mainly for the manufacture of high-strength, lightweight military equipment and protective materials. Titanium alloys have important applications in military equipment due to their high strength and lightweight characteristics. Titanium alloys are superior materials for the manufacture of mortar tubes, base plates, gun barrels, gun mounts, etc., and are also good materials for the preparation of protective clothing and helmets.
4. Chemical industry
Chemical industry is still the largest titanium-using industry in my country. The main application industries in this field are PTA, chlor-alkali, soda ash, inorganic salt and vacuum salt making industries. The main applications include electrolytic cells (electrodes), reactors, concentrators, separators, heat exchangers, coolers, absorption towers, connecting pipes, accessories (flanges, bolts, nuts), gaskets, pumps, valves, etc.
