Tungsten sheets/ plates

Tungsten plates utilizing our original rolling know-how
We also manufacture tungsten, a difficult-to-process material, from thick to thin plate,utilizing our unique rolling know-how. Tungsten has the highest melting point among metals and is used for high-temperature furnace components, electrodes, and other applications. We can also supply the world's highest purity tungsten sheets for sputtering targets, taking advantages of our integrated production system from raw materials.

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