  • Aerospace and Defense: Tungsten plates are used in aerospace and defense applications due to their high density, heat resistance, and ability to absorb radiation. They are used in the manufacturing of aircraft and spacecraft components, rocket nozzles, and radiation shielding.
  • Electronics and Semiconductor: Tungsten plates are used as substrates for electronic components, contacts, and lead-in wires. Their high melting point and electrical conductivity make them ideal for use in semiconductor devices.
  • Medical Imaging and Treatment: Tungsten plates are used as X-ray targets and as components in radiation therapy machines. Their high density and ability to absorb radiation make them ideal for these applications.
  • Industrial Applications: Tungsten plates are used in various industrial applications such as furnace components, welding electrodes, and tooling. Their high melting point, hardness, and wear resistance make them suitable for these applications.
  • Automotive: Tungsten plates are used in the automotive industry for manufacturing of various components such as electrodes for spark plugs and balancing weights.
  • Nuclear Industry: Tungsten plates are used in the nuclear industry for radiation shielding and as components in nuclear reactors.
  • Raw Material Preparation: The process starts with the preparation of high-purity tungsten powder, with a purity level of 99.95% or higher.
  • Powder Compaction: The tungsten powder is then compacted into a blank or a preliminary form using a hydraulic press.
  • Sintering: The compacted tungsten blank is then sintered in a high-temperature furnace. This process removes any remaining impurities and allows the tungsten particles to fuse together, forming a solid, dense material.
  • Rolling: The sintered tungsten blank is then subjected to a series of rolling processes to reduce its thickness and achieve the desired dimensions. The rolling process also helps in improving the mechanical properties of the tungsten plate.
  • Annealing: After rolling, the tungsten plate is annealed to relieve any internal stresses that may have developed during the rolling process. This helps in improving the ductility and workability of the tungsten plate.
  • Surface Treatment: The surface of the tungsten plate is then treated to achieve the desired finish. This may involve processes such as grinding, polishing, or chemical etching.
  • Inspection and Quality Control: The finished tungsten plate is then subjected to a series of inspections and quality control checks to ensure that it meets the specified tolerances and quality standards.
  • Packaging and Shipping: Once the tungsten plate has passed all the quality checks, it is carefully packaged to prevent any damage during transportation and shipped to the customer.

EPI Materials supplies high-quality tungsten plates that are suitable for these applications and more. Our expert team can work with you to customize tungsten plates to meet your specific needs.
