Tungsten sheets/ plates
Tungsten plates manufactured using proprietary kow how
From thick to thin sheets, we manufacture tungsten material, a difficult-to-work material, using our rolling know-how.
Tungsten, which has the highest melting point among metals, is used for high temperature furnace parts and electrodes.
We can also offer the world's No.1 grade high purity tungsten sheets / plates for sputtering targets takig advantage ofour oun integrated production.
