Vacuum plating tungsten wire means the tungsten wire that can be applied for electroplating under vacuum conditions. There are door shaped tungsten wire, wave shaped tungsten wire, and so on. Vacuum plating tungsten wire is the main material for tungsten heater, which has the characteristics of high melting point and strong resistance to corrosion so that it is mainly applied as a heating element for vacuum coating in mirror making, picture tube, toys and household appliance, etc. While the uniformity…

Optical tungsten wire means the tungsten wire that is applied in the field of optics, such as bulbs. The bulbs in optical industry include tungsten filament bulb, tungsten halogen bulb, fluorescent tube, metal halide bulb, and LED bulb, among which tungsten filament bulb is the earliest used optical bulb. A more energy-efficient and brighter tungsten halogen bulb can be obtained by improving the tungsten wire. The optical instrument is equipped with one or more bulbs to illuminate the object to…

Photoelectricity tungsten wire means the tungsten wire that is used in the photoelectric industry, such as fiber optic communication, photoelectric material and component, electro-optical display device, laser, optical storage, and so on. The reason why tungsten wire can be used in photoelectric industry is due to its own excellent physical and chemical properties, such as high melting point, good corrosion resistance, high resistivity, low vapor pressure, and the like. With the rapid development of electric light source, there are increasingly…

Coiled filament can be used for the production of incandescent lamps, with single helix type, double helix type and other types. Why coiled filament is applied for producing incandescent lamps? Here are some reasons: 1. The filament is very thin so that it is fragile if it is working under high temperature for a long time. While the helix structure can play a role of buffer to prevent it from breaking under vibration. 2. Light is emitted from the incandescent…

IG tungsten filament is the short for ion source gun tungsten filament, which is made of thin tungsten wire with small size. It can be applied in the coating system. Also, it can be found in ion implanter, which has been applied for manufacturing semiconductor devices. The ion implanter is widely used all over the world as it is indispensable in the manufacture of a variety of semiconductor products like computer CPUs, DRAM, flash memory, and system LSI, as well…

EB tungsten filament, the short for electron beam tungsten filament, is a filament for an electron gun as its name suggests, which is mainly used to emit electron beams. And the electron gun can be used as a medical accelerator for the radiation therapy device. There are several common seen EB tungsten filaments, such as mosquito coil shaped EB filament, centerless mosquito coil shaped EB filament, S shaped EB filament, arch shaped EB filament, L door shaped EB filament, door…

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…
