Porous Tungsten

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

Porous tungsten is produced by low-temperature sintering, opposite to normal tungsten products which are sintered at high temperature (>2000℃). Porous tungsten can be used as high current density cathode, which is an important usage for tungsten products. Its porous skeleton is a vital part of dispenser cathode. This can be used in aerospace, power electronics and metallurgical industries. Porous tungsten is used to filtering high temperature liquid & gas. 

Properties of our porous tungsten:

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