Aerospace field
Titanium has been widely used in the aerospace field because of its high strength, high heat resistance and high specific strength. Titanium alloy can reduce the overall weight of the aircraft while improving the aircraft's bulletproof capability, reduce the distance of the aircraft takeoff/landing runway, and increase the aircraft's maneuverability, maneuverability and mounting capacity.
With the increasing of China's national strength, its ability to safeguard maritime rights and interests is also increasing, and the number of carrier-based aircraft is also increasing, so the demand for seawater corrosion-resistant titanium materials will increase year by year.
Petrochemical industry
Studies show that titanium alloy is still the preferred material under high temperature and pressure, high corrosive medium and high chlorine environment. Since the corrosion resistance of titanium and titanium alloy are mainly used in the petrochemical field and the heat resistance is not high, the types of titanium materials are relatively simple compared with the titanium materials used in the aerospace field. The main titanium materials are industrial pure titanium and TA10. The prices of these two titanium materials are relatively cheap, and their melting technology, processing technology and welding technology are relatively mature in China, so they can be widely used in the domestic petrochemical field.
Field of ocean engineering
Due to its excellent corrosion resistance to seawater and ocean atmosphere, minimal dissolved ions, non-toxicity and no pollution to the environment, titanium material can well meet the application requirements of Marine engineering. Marine engineering is expected to become a new civil market for titanium. In Marine engineering, titanium is mainly used in offshore oil and gas development, seaside construction, coastal power plants, seawater desalination plants, ships, Marine fisheries, ocean energy conversion and other fields. The application of titanium in the field of ocean engineering can not only reduce the quality of related equipment, but also reduce the maintenance cost and extend the service life of related equipment. For example, if titanium is used in a ship, its equipment life can be extended to 30 to 40 years, while aluminum alloy, mild steel and other ships need maintenance in 10 years. Moreover, titanium material also has excellent low temperature performance, can maintain a certain plasticity at -253℃, and the volume change in low temperature environment is small, very suitable for the Arctic icebreaker and other uses.
Biomedical Sciences
Because of its light weight, low elastic modulus, non-toxicity, non-magnetism and low biological reaction, titanium has been recognized as the most ideal metal material for human implants in the field of biomedicine. Titanium and titanium alloy materials are widely used in orthopaedic surgery, cardiovascular system, neurosurgery, oral surgery and human external culture machine. In addition, titanium material is also used in biopharmaceutical fields because of its non-toxic and good bactericidal effect of TiO2 surface. In terms of human implants, titanium is used to prepare femoral head, dental implants, hip joints, knee joints, prostheses, fastening screws, etc. It can also be seen that titanium is mainly used in orthopedics, and orthopedics implant biomaterials account for about 38% of the market share, making it the largest market for implant biomaterials. Orthopedic implant products mainly include spinal products, trauma products, artificial joint products and neurosurgical products.
