Tungsten sheets/ plates

Tungsten 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.
