Tungsten Sheet Applications
Tungsten sheet is made from our 99.95% pure tungsten powders. The tungsten powders are pressed, sintered and forged to tungsten blanks in an isostatic and highly high-temperature environment. Afterward, our state-of-the-art hot and cold rolling processes turn the tungsten blank to high quality tungsten sheet. Our experienced engineers work closely with our customers to customize the product’s parameters to the customer’s requirements. Due to its wide variety of valuable properties, many applications require tungsten as a machinable material, such as heat shields, heating element and supports of the high-temperature furnace, CT scanner, ion implantation and evaporation boats, to name a few.
- Heat shielders
- Heat bodies
- Furnace support frames
- Tungsten boats for sapphire crystal furnaces and vacuum furnaces
- Tungsten sputtering targets for the vacuum coating and evaporation coating
- Ion sources for ion implantation equipment
