Tungsten plate and tungsten sheet are isostatically pressed and sintered from our high purity tungsten powders to compact ingots by powder metallurgy. Following the powder metallurgy is a series of further deformations and heat treatments until the required products are finished. We are now capable of machining tungsten plate and sheet with a range of thickness from 3.15 inches (80 mm) to less than 0.004 inches (0.1 mm).

XOT metals is a recognized manufacturer and supplier of high quality tungsten plate and tungsten sheet.  Every tungsten plate we supply is under stringent quality control at every stage of production, including the rolling, annealing, surface treatment and a series of tests. Thanks to our experience and capacity in the field of milling tungsten product, we can always guarantee that our customers receive high-performance tungsten plate products with exceptional purity, roughness, dimension, flatness and surface condition.

High Temperature Furnace

Tungsten plate has a high heat resistance. Its high melting point allows it to serve well as the material in high-temperature furnace components. Heating elements, heat shields and boats of high-temperature furnaces are required to be resistant to a working temperature up to 1300 °C. Therefore, all of them are mainly made of tungsten plate and tungsten sheet. In the metallurgical industry, some components of electric-resistance furnaces are made of tungsten flat products. These furnaces are used to sinter refractory metals into billets and semi-finished products. The refractory metals include tungsten, molybdenum, tantalum and niobium.

Tungsten heating elements are the core part of high temperature furnaces. The working temperature can rise up to 2800°C and stay in 2300 -2350°C for a long time. The heating element is usually in the shape of a cylindrical shell or pieces of closed-end tungsten sheets riveted by tungsten bolts. Tungsten heat shields are the heat insulating part of high temperature furnaces. The riveted tungsten sheet is popular to make the most internal layer of the shields.
