Titanium is an inert metal with the chemical symbol ti and the atomic number 22. It is a silver metal. The specific gravity is 4.51 and the melting point is 1668℃. It is abundant in the earth's crust. It ranks fourth after iron, aluminum and magnesium, and is more than ten times more than the sum of the commonly used metals copper, nickel, lead and zinc. The ores used to produce titanium in industry include rutile, ilmenite and titanomagnetite. Due to the difficulty in separation and extraction, the metal titanium with industrial significance was not produced until the 1940s. Therefore, titanium is generally called a rare light metal. Due to the different titanium and titanium alloy products required by different products in different fields, people process them into plates, rods, tubes, strips, wires, etc., which can be provided to the majority of demanders in deep-processed shapes to meet the needs of different fields. Among them, titanium plates, titanium rings, titanium forgings, etc. are the most widely used.

Surface quality
The surface of the titanium plate should be smooth and metallic in color. Plates are allowed to be delivered with a sandblasted surface. Slight darkening and local water marks are allowed on the surface of the titanium plate; local defects are allowed, including scratches, indentations, dents and other defects that do not exceed half of the thickness tolerance, but the minimum thickness should be guaranteed. The surface is not allowed to have macro defects such as cracks, peeling, oxide scale, pressure folding, metal and non-metal inclusions, and traces of alkali cleaning. Titanium plates are allowed to clear local defects along the rolling direction, but the thickness of the plate after removal is not less than the minimum allowable thickness.In addition, the titanium plate should not be delaminated.
Application of titanium plates
Titanium and titanium alloys have low density and high tensile strength. In the range of -253-600 degrees Celsius, its specific strength is almost the highest among metal materials. It can form a thin and hard oxide in an appropriate oxidizing environment. Physical film with excellent corrosion resistance. In addition, it is non-magnetic and has a small linear expansion coefficient. This made titanium and alloys first known as important aerospace structural materials, and then extended to shipbuilding, chemical industry and other fields, and developed rapidly. Especially in the chemical industry, titanium and titanium alloy products are used in more and more products, such as exchangers, reaction towers, synthesizers, etc. in industries such as petrochemical, fiber, pulp, fertilizer, electrochemistry and seawater desalination. Autoclave etc. Among them, titanium plates are used as electrolytic plates and electrolytic cells in electrolysis and sewage desalination, and are used as tower bodies and kettle bodies in reaction towers and reaction kettles.
With the development of science and technology, the application fields of titanium materials are becoming more and more broad, such as medical, automobile, sports, etc. Through these, it is truly reflected that titanium, as a light metal, has more and more excellent characteristics. It is recognized and identifiable by people, and it replaces other metals at the fastest speed and is integrated into our production and application fields, and even our bodies.
