Non-sag tungsten wire is also called doped tungsten wire, which is doped with the element of K (potassium) or other elements. It can be used as a filament in electric lamps. The beneficial effects of doping to improve the creep resistance of tungsten wire were recognized as early as 1910, and doping was practiced henceforth. For example, tungsten oxide powder is doped with potassium-containing chemicals. Non-sag tungsten wire is unique in that it is a composite between two mutually insoluble…

High temperature tungsten rhenium thermocouple has the advantages of high operating temperature and low cost, so that it can be used as a substitute for platinum rhenium thermocouple. The tungsten rhenium thermocouple may be applied in measuring temperatures at the range of 1600~3000°C. Characteristics of High Temperature Tungsten Rhenium Thermocouple 1. Well suited for measuring extremely high temperatures. 2. Typical uses are hydrogen and inert atmospheres, as well as vacuum furnaces. 3. A typical range is 0 to 2315°C, which…

Gold plated tungsten rhenium wire is a gold coated wire with high tensile strength, which is even stronger than gold coated tungsten wire. The gold plated tungsten rhenium wire has the characteristics of beautiful appearance and good oxidation resistance. More importantly, it has excellent corrosion resistance, and therefore it can be used as a thermal element for thermal conductivity cell detector (TCD). Gold is insoluble in acid or alkali. And it will not be directly oxidized under any circumstances. The…

Gold plated tungsten wire means the tungsten wire is plating with gold, which is very suitable for use in harsh environments. For instance, it has wide applications in printing, antennas, medical, technical research, and so on. Plating is providing oxidation resistance and improved wettability for welding. The gold plated tungsten wire will not change in density compared to unplated tungsten wire of the same diameter as tungsten and gold are almost equal in density. While the electrical resistance of the…

Tungsten filament may be applied as a heating filament for electrical cigar-lighter, which is a common feature of automobiles and trucks. The electrical cigar-lighter is powered by an electrical cigar-lighter, which is also known as cigarette lighter receptacle, cigar lighter receptacle or cigar lighter socket. While the cigarette lighter receptacle became a standard DC connector to supply electrical power for portable accessories used in or near an automobile. With the decline in the popularity of smoking, automobiles may provide several…
