Tungsten sheets/ plates

Tungsten sheets/plates produced using our original rolling techniques.
We manufacture tungsten, a challenging material to process, into plates ranging from thick to thin, utilizing our proprietary rolling techniques. Tungsten, with the highest melting point among metals, is used in high-temperature furnace components, electrodes, and various other applications. Additionally, we provide the world’s highest purity tungsten sheets for sputtering targets, benefiting from our integrated production system starting from raw materials.

Applications X-ray shielding materials, structural components for furnaces, electrodes, etc.

Finished surface of Tungsten sheets / plates

Finished surface Surface roughness (μm)
(Typical value)		 Features
Rolled Ra3.0 This is the most common tungsten sheets / plates. Plates with a thickness of 3 mm or less can be heated, bent, and pressed. We also offer tungsten sheets / plates that have been sufficiently deformed to facilitate cutting and polishing processes.
Mirror Ra1.6 This tungsten sheet has been repeatedly rolled to reduce the unevenness of the surface and to add luster to the sheet.
CC Ra2.9 Acid cleaning is applied to reduce variations in surface conditions caused by rolling.
Cutting Ra2.0 If greater precision is required than what is achieved with the rolling finish, the surface is machined.
Polishing Ra0.6 If you require a higher degree of precision or smoother surface roughness than can be achieved through cutting and finishing, polishing is an option.
Horning Ra2.5 Material blasted with alumina abrasive.
