Applications
Tungsten has an electrical conductivity twice that of steel. The use of tungsten in electrical engineering is limited to the manufacture of spirals for electric lamps and contacts for some electrical apparatus. A new area of use of tungsten and its alloys is emerging - as cathode materials for thermoelectronic converters (TEC) that can serve as onboard power sources for spacecraft. In electronics, the best results are obtained with high purity tungsten.
