Porous tungsten (W) is used in aeronautic and aerospace engineering, power electronics, and metallurgical industries.

Edgetech Industries LLC provides porous tungsten rod, sheet and disc with porosity from 20% to 50%.

Porous tungsten is produced through low-temperature sintering, which is different from ordinary tungsten products in high-temperature (>2000°C) sintering. It can be used as a high current density cathode, which is an important use of tungsten products. Its porous skeleton is an important part of the distributor cathode. This can be used in the aerospace, power electronics, and metallurgical industries. It can also be used to filter high-temperature liquids and gases.

Properties of our porous tungsten

  • High melting point
  • Low density
  • High strength
  • Low thermal expansion coefficient
  • Extraordinary corrosion resistance
