High purity tungsten plate, a must-have product for the industry.

Short Description:

Tungsten plate

Tungsten sheet is a type of plate made from tungsten metal, a metal with a very high melting point (approx. 3422°C), high density (approx. 19.25 g/cm³) and excellent mechanical strength. These properties make tungsten and its products useful in many high-temperature environments and specialised applications. Tungsten sheets are usually produced by powder metallurgy or other processing techniques and can be cut to different sizes and thicknesses as required.

The Production Method Of  Tungsten Plate

Tungsten plates are produced mainly through the process of powder metallurgy, which is a method of pressing and shaping metal powders and then sintering them at high temperatures to form a solid material.
Tungsten powder preparation begins with the selection of a suitable tungsten powder, a step that is critical to the purity and performance of the final product. The particle size, shape and purity of the tungsten powder will affect the production process and the quality of the final product.
Press forming puts the tungsten powder into a mould and presses it into the desired shape under pressurised conditions. In the case of tungsten plates, this usually means pressing into a thick plate shape. Pressing can be either cold or hot. Hot pressing can be done at higher temperatures to help improve the formability of the powder.
High-temperature sintering After pressing and forming, the tungsten sheet needs to be sintered in a furnace at a high temperature. The sintering process takes place below the melting point of tungsten, usually at temperatures between 1600°C and 2200°C. The sintering process allows the tungsten powder particles to be sintered at higher temperatures. Sintering causes the tungsten powder particles to bond with each other to form a dense solid structure. Hot and cold rolled sintered tungsten sheets may be further processed through hot and cold rolling processes to achieve final thickness and flatness requirements. Hot rolling is carried out at higher temperatures to help reduce the hardness of the material and increase its plasticity. Cold rolling, on the other hand, is carried out at room temperature to increase the strength and hardness of tungsten plates.
Heat treatment and annealing As required, tungsten plates may also undergo heat treatment and annealing processes to adjust their microstructure and mechanical properties such as hardness, toughness and corrosion resistance.
Surface Treatment and CuttingFinally, the surface of the tungsten plate may require grinding or other types of surface treatment to achieve the desired surface roughness. Depending on the customer's specific requirements, tungsten plates can also be cut to specific sizes and shapes.
