Edgetech Industries LLC provides porous tungsten rod, sheet and 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℃). It 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. It is also used to filtering high temperature liquid & gas.
Properties of our porous W
·High melting point
·Low thermal expansion coefficient
·Extraordinary corrosion resistance
