Titanium Plate - A Comprehensive Knowledge Introduction!

1. Introduction to Titanium Plate

Titanium plate is a metal plate made from titanium as the raw material. Titanium is a very special metal. It is extremely lightweight, yet very tough and corrosion - resistant. It doesn't turn black like silver and maintains its own color throughout its lifetime at room temperature. The melting point of titanium is similar to that of platinum. It is widely used in metallurgy, electronics, medical treatment, chemical engineering, petroleum, medicine, aerospace and other industries.

2. Execution Standards of Titanium Plate

• Chinese Standards: GB/T3621 - 2007, GB/T13810 - 2007

• American Standards: ASTM B265, ASTM F136, ASTM F67, AMS4928

3. Manufacturing Processes of Titanium Plate

• Hot Forging: It is a forging process carried out above the metal recrystallization temperature.

• Hot Rolling: It is a rolling process carried out above the recrystallization temperature.

• Cold Rolling: It is a rolling process in which the plastic deformation temperature is lower than the recovery temperature.

• Annealing: It is a metal heat - treatment process in which the metal is slowly heated to a certain temperature, maintained for a sufficient time, and then cooled at an appropriate speed (usually slow cooling, sometimes controlled cooling).

• Pickling: The workpiece is immersed in an aqueous solution such as sulfuric acid to remove oxide films on the metal surface. It is a pre - treatment or intermediate treatment for electroplating, enameling, rolling and other processes.

4. Characteristics of Titanium Plate

• The oxide film on the surface of the titanium plate is equivalent to a good and durable separating agent for usage. Using titanium plates saves the separating agent, makes the plate easy to peel, and eliminates the pre - treatment process of the plate. The titanium plate is half as light as the copper seed plate.

• The service life of the titanium plate is more than three times that of the copper seed plate and can reach 10 to 20 years according to the operating conditions.

• The electrolytic copper produced by using titanium plates has a dense crystal structure, a flat and smooth surface, and excellent quality.

• Since the titanium plate does not need to be coated with a separating agent, the contamination of the copper electrolyte can be avoided.

• It improves production capacity and reduces the production cost of electrolytic copper, thus having good economic benefits.

5. Surface Quality of Titanium Plate

• The surface of the plate should be smooth and have the original color of the metal. The plate is allowed to be supplied with a sand - blasted surface.

• Slight darkening and local water marks are allowed on the plate surface. Local scratches, indentations, pits and other defects that do not exceed half of the thickness tolerance are allowed, but the minimum thickness should be ensured.

• Cracks, peeling, oxide scale, creases, metal and non - metal inclusions and other macroscopic defects and over - alkali - washed marks are not allowed on the surface of the plate.

• Local defects are allowed to be removed along the rolling direction of the plate, but the thickness of the plate after removal shall not be less than the minimum allowable thickness.

• When there are special requirements for the surface quality of the plate, the supply can be negotiated between the supplier and the demander.
