Product Code : AL-WSi2-CU
Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.
Tungsten Disilicide Powder (WSi2 Powder) is a conductive ceramic material with a high melting point and good oxidation resistance. WSi2 Powder is mainly produced by chemical vapor deposition and the powder size can be customized. WSi2 is mostly used in microelectronics as a contact material due to its small resistance. It’s also used as a shunt over polysilicon lines to increase the conductivity and signal speed.
ATT is a professional supplier of Tungsten Disilicide Powder (WSi2 Powder), We also produce disc, granules, ingot, pellets, pieces, powder, rod, wire, sputtering target and in numerous other forms and custom shapes. Other shapes are available by request.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.

Applications of Tungsten Disilicide Powder (WSi2 Powder)
Tungsten Disilicide Powder (WSi2 Powder) is widely used in making semiconductors and microelectronics as a diffusion barrier layer preventing the migration of metal atoms. WSi2 powder is also used as a heat-resistant material that is used in the aerospace area. Due to its high-temperature oxidation and corrosion resistance, WSi2 can be used as a coating material to form a layer to protect the main metal part and increase the lifetime of a material. WSi2 powder also shows appear in additive manufacturing to make high-strength products.
Packing of Tungsten Disilicide Powder (WSi2 Powder)
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
