Tungsten bar is a power vacuum lighting materials

TungstenKekai tungsten & Molybdenum Technogy tungsten bar filament , tungsten bands and various forging components for tube production, radio electronics and X -ray technology . Incandescent tungsten filament is helical filaments and the best materials. High temperature (2200 - 2500 ℃) ensure a high luminous efficiency , and a small rate of evaporation of the wire to ensure a long life . tungsten carbide ball for manufacturing an electronic oscillator tube straight hot cathode and a gate , and a high-voltage rectifier and the cathode side in various electronic instruments hot cathode heater. For contacts made ??with tungsten carbide rod cathodes and cathode and atomic and hydrogen torch electrode radio equipment X-ray tube and the gas discharge tube . Tungsten and tungsten rod as a high temperature furnace (3000 ℃) heater . Tungsten heater in a hydrogen gas , an inert gas or in vacuum .
