Tungsten Ribbon Coil

Another important use of pure tungsten ribbon coil is to make tungsten targets. The factors that affect the effect of the target are thickness, surface, thickness and grain direction. Normally, the target is used for thin sections with a purity above 99.90% and a density of 19.0g/cm3. The surface of the target may be rough or smooth, but the smooth surface is the final use product. To achieve this surface, electrolytic polishing is the most commonly used production method. Chemical vapor deposition, physical vapor deposition, mechanical rolling, mechanical grinding polishing, chemical polishing and electrolytic polishing can also be used in the preparation of tungsten foil film.

Powder metallurgy is a method of producing tungsten sheets, in which this Tungsten Ribbon Coil is mainly rolled from tungsten sheets. The density can also be increased through the rolling process.
