Titanium Plate Gr2

Titanium plate is a metal plate made of titanium. Titanium is a very special metal. It is very light, but very tough and corrosion-resistant. It will not turn black like silver, and it will keep its color at room temperature for life. The melting point of titanium is similar to that of platinum. It is widely used in metallurgy, electronics, medical treatment, chemical industry, petroleum, medicine, aerospace and other industries.

GR2 is an industrial titanium with a single α phase. Industrial pure titanium is divided into three grades: GR1, GR2 and GR3 according to the different impurity contents. The interstitial impurity elements of these three types of industrial pure titanium gradually increase, so their mechanical strength and hardness also increase step by step, but the plasticity and toughness decrease accordingly. When the iron content ω is 0.095%, the oxygen content ω is 0.08%, the hydrogen content ω is 0. 0009%, and the nitrogen content ω is 0.0062%, GR2 has good low-temperature toughness and high low-temperature strength, and can be used as a low-temperature structural material below -253°C.

Hot forging: a forging process performed above the metal recrystallization temperature.

Hot rolling: a rolling process performed above the recrystallization temperature.

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

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

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

1. The surface oxide film of the titanium plate is equivalent to a good, durable, and wear-resistant separator. The use of a titanium plate saves separators, makes it easy to peel off the plates, and eliminates the process of pre-treatment of the plates. Titanium plates are half light as copper seed plates. 2. The service life of the titanium plate is more than 3 times that ofthe copper seed plate, and can reach 10-20 years depending on the operating conditions.

3. The electrolytic copper made from a titanium plate has a dense crystal structure, a smooth surface, and excellent quality.

4. Since the titanium plate does not need to be coated with a separator, it can avoid contamination of the copper electrolyte.

5. Increasing production capacity and reducing the production cost of electrolytic copper, thus achieving better economic benefits. plate.

1. The surface of the plate should be smooth and metallic in color. Plates are allowed to be supplied with sandblasted surfaces.

2. Slight darkening and local water marks are allowed on the surface of the plate; local scratches, indentations, pits, and other defects that do not exceed half of the thickness tolerance are allowed, but the thickness should be kept small;

3. The surface of the plate is not allowed to have macro defects such as cracks, peeling, oxide scale, folds, metal and non-metal inclusions, and traces of over-alkali washing;

4. Plates are allowed to remove local defects along the rolling direction, 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 by both the supply and demand parties.
