What Is Cleaned Tungsten Wire?

Cleaned tungsten wire is the tungsten wire after alkali cleaning or electrolytic polishing of black tungsten wire. Compared with black tungsten wire, the surface of cleaned tungsten wire is smooth, bright and clean. The cleaned tungsten wire shortly after alkali cleaning has a silver-gray metallic luster.

Tungsten has a high melting point, high thermal stability and good electrical conductivity, so cleaned tungsten wire is very suitable for manufacturing high-temperature and high-power equipment. Cleaned tungsten wire is usually used to manufacture light bulbs, vacuum electronic devices, electron guns, and high-temperature furnaces.
