Contact material and high specific gravity alloy tungsten - copper (10%~40% copper) and tungsten - silver alloy manufactured by powder metallurgy, both copper and silver have good electrical conductivity, thermal conductivity and wear resistance of tungsten. Therefore, it becomes a very efficient contact material for manufacturing knife switch, circuit breaker, spot welding electrode and other working parts. High gravity alloys of 90%~95% tungsten, 1%~6% nickel, 1%~4% copper, and alloys of iron for copper (~5%) are used in the manufacture of gyroscopes rotors, airplanes, counterweights for rudder control, radiological shields and basket for radioactive isotopes, etc. Tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, molybdenum tube, tungsten crucible, molybdenum crucible

Electric vacuum lighting material tungsten is used in tube production, radio electronics and X-ray technology with tungsten wires, tungsten bands and various forged components. Tungsten is the best material for white filament and spiral filament. High operating temperature (2200~2500℃) ensures high luminescence efficiency, and small evaporation speed ensures long life of wire. Tungsten wires are used in the manufacture of direct hot cathodes and grids for electronic oscillating tubes, cathodes for high voltage rectifiers and side hot cathode heaters for various electronic instruments. Tungsten is used as cathodes and countercathodes for X-ray and gas discharge tubes, as well as contacts for radio equipment and atomic hydrogen torch electrodes. The tungsten wire and tungsten rod serve as the heater for the high temperature furnace (up to 3000℃). Tungsten heaters operate in hydrogen atmosphere, inert atmosphere or vacuum.
