Porous Tungsten

Category:

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

Specification of our porous W products:

Product Item Code Size Porosity
Rod POM74-WR 3- 20mm diameter x 600mm length Max 20-40%
Sheet POM74-WS 2.5-20mm thick x 10~100mm width x 10~100mm length 20-50%
Disc POM74-WD 2.5-20mm thick x 10~100mm diameter 20-50%

Regular specification we have for porous tungsten rod is 6.35mm diameter x 500mm L with around 23% porosity. We can cut to length per request, but should be >20mm. We also provide porous titanium products.

Edgetech Industries LLC began offering Tungsten and other refractory metals products years ago. We specialize in providing worldwide customers with all types of Tungsten fabricated products (such as crucible, rod and bar, sheet and plate, etc.), heavy alloy that is mostly used as weights and shielding, composites (such as CuW, AgW) that is used for electrode contacts, and carbide alloy using as tools. Contact us at sales@edgetechmat.com for inquires and more information of tungsten.
