Introduction to Titanium Plate

Introduction to Titanium Plate

Titanium plate is a kind of metal plate made from titanium as the raw material. Titanium is a rather special metal. It is extremely lightweight yet very tough and corrosion-resistant. Unlike silver which will turn black, titanium maintains its original color throughout its lifetime at room temperature. The melting point of titanium is similar to that of platinum. It is widely used in industries such as metallurgy, electronics, medical treatment, chemical engineering, petroleum, medicine, and aerospace.

Execution Standards of Titanium Plate

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

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

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 where 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 like sulfuric acid to remove oxide films and other thin films on the metal surface. It is a pre-treatment or intermediate treatment for electroplating, enameling, rolling and other processes.

Characteristics of Titanium Plate

1. The oxide film on the surface of the titanium plate is equivalent to a good and durable separating agent. Using titanium plates can save the separating agent, make it easy to peel the electrode plates, and eliminate the pre-treatment process of the plates. The titanium plate is half as light as the copper seed plate.

2. 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 under certain operating conditions.

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

4. Since the titanium plate doesn't need to be coated with a separating agent, it can avoid the pollution of the copper electrolyte.

5. It can increase production capacity and reduce the production cost of electrolytic copper, thus bringing good economic benefits.

Surface Quality of Titanium Plate

1. The surface of the plate should be smooth and present the original color of the metal. The plate is allowed to be supplied with a sandblasted surface.

2. 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.

3. Cracks, peeling, oxide scale, creases, metal and non-metal inclusions and other macroscopic defects as well as the marks of excessive alkali washing are not allowed on the surface of the plate.

4. 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.

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