What are the classifications, grades, and application fields of titanium and titanium alloy plates?

1、 Classification of titanium and titanium alloys
In 1956, McGovern proposed a method for classifying titanium and titanium alloys based on the composition of phases in the annealed state, which classified titanium and its alloys into four categories: pure titanium, alpha titanium alloys, alpha+beta titanium alloys, and beta titanium alloys.
The titanium alloy symbols in our country start with TA, TB, and TC, respectively representing alpha titanium alloy, beta titanium alloy, and alpha+beta titanium alloy.

3、 Application areas:
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 for engines. In civil aircraft, it is mainly used as structural frames for the fuselage, midsection, and inner arm plates. Mainly utilizing its low density, high strength, high temperature resistance, corrosion resistance and other properties. It has also achieved the goal of reducing launch mass, increasing range, and saving costs, making it a popular material in the aerospace industry. In the rocket, missile, and aerospace industries, it can be used as a pressure vessel, fuel storage tank, rocket engine casing, rocket nozzle casing, artificial satellite shell, manned spacecraft cabin (skin and structural skeleton), landing gear, lunar module, propulsion system, etc.
2. Medical field
Titanium and its alloys have the characteristics of non toxicity, light weight, high specific strength, resistance to biological corrosion, and good biocompatibility. They are ideal medical metal materials widely used in the fields of artificial bones, artificial joints, dentistry, plastic surgery, cardiac surgery, internal support frames, and medical devices.
3. Military field
Titanium is widely used in the military field, mainly for manufacturing high-strength and lightweight military equipment and protective materials. Titanium alloy has important applications in military equipment due to its high strength and lightweight characteristics. Titanium alloy is an excellent material for manufacturing mortar barrels, seat plates, gun barrels, gun mounts, etc. It is also a good material for preparing protective clothing and helmets.
4. Chemical industry field
The chemical industry is still the largest titanium using field in China. The main application industries in this field are PTA, chlor alkali, soda ash, inorganic salts, and vacuum salt production industries. There are mainly electrolytic cells (electrodes), reactors, concentrators, separators, heat exchangers, coolers, absorption towers, connecting pipes, fittings (flanges, bolts, nuts), washers, pumps, valves, etc.
