Tungsten Sheet
Tungsten Sheet
Brief introduction:
Tungsten belongs to rare metals and

tungsten cost

is different according to various tungsten content.

Tungsten sheet

is one of tungsten products. Tungsten sheets are produced by good processing property billets and special cold and hot rolling technology. The crystal structure of tungsten sheet is compact.
The difference between tungsten sheet and tungsten plate is that tungsten sheet is thinner than tungsten plate.

Tungsten sheet can be divided into hot rolling tungsten sheet, warm rolling tungsten sheet and cold rolling tungsten sheet.

Due to the resistance to deformation of tungsten is big, the ordinary mill roll can not totally meet the requirements of tungsten sheet rolling. Some tungsten sheet should be rolled by mill roll made of special material. Before rolling tungsten sheet, manufacturers need preheat the mill roll.  The preheating temperature is 100 ℃ to 350 ℃ according to the different rolling conditions. If the relative density of the semifinished tungsten sheet   (the actual density and theoretical density ratio) is greater than 90%, then manufacturers can machine the tungsten sheet. If the density of the semifinished tungsten sheet is 92 to 94%, the processability of tungsten sheet is excellent. The blooming temperature of hot rolling is 1350℃ to 1500 ℃. If the deformation technological parameters are improperly selected, then the semifinished tungsten sheet will appear lamination. The blooming temperature of warm rolling is 1200 ℃. Hot rolling tungsten sheet with 8 mm thickness can be rolled into 0.5 mm by warm rolling.

Applications of tungsten sheet:
Tungsten sheet can be used to make tungsten electrodes, tungsten heat elements, tungsten heat shields and tungsten boats for electronics, lightening, electro-vacuum industries.
