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…

Doped tungsten wire means?the tungsten wire which is added with dispersion strengthening element K to increase the high temperature creep resistance. The grades are W31, W61, W91, and WR15. The wire winding performance of the doped tungsten wire is related to its composition, structure properties, and wire winding conditions. Domestic manufacturers are facing a difficult problem – wire cracking. Therefore, it is of great significance to know the influence of tensile strength of doped tungsten wire upon wire winding performance.…

Straightened tungsten wire has the characteristics of high temperature performance, good machining performance, high recrystallization temperature, and good resistance to high temperature sag performance so that it can be directly cut for manufacturing tungsten needle or electrode. Straightened tungsten wire includes straightened black tungsten wire, straightened cleaned tungsten wire, straightened tungsten rhenium wire, and the like. This type of tungsten wire can be obtained through drawing process and straightening process. Drawing process is to heat the metal tungsten to plasticity,…

Stranded tungsten wire is bright silver gray and uniform in color. And there is no visible contaminant, obvious burrs, cracks, and oxidation phenomenon on the surface. The monofilament has no breakage, and the spiral coil is slightly elastic. Besides, it can be used to evaporate pure aluminum wire with a life of more than 12 heats. Stranded Tungsten Wire Application It can be used as a resistance heater for mirror making, aluminum film evaporation, and electric vacuum, electronic device or…

Tungsten rhenium wire has the characteristics of good tensile strength, elongation, anti-seismic performance and non-sag performance so that it can be used to produce filaments for lighting. Performance Comparison of Tungsten Rhenium Wire and Tungsten Aluminum Wire The performance of tungsten rhenium wire is better than that of tungsten aluminum wire, which can be seen from the following points: 1. The density of tungsten rhenium wire is 19.65g/cm3, and tungsten aluminum wire is 19.3g/cm3. 2. The elongation of tungsten rhenium…

Cleaned tungsten wire ?is referred as to the tungsten wire that has been electrolytically cleaned and polished with smooth and clean surface. Cleaned tungsten wire can be used in an atomizer. Tungsten atomizer has the advantages of small size and low energy consumption. Also, it is suitable for on-site and real time analysis. Therefore, it will play an important role in the field of atomic spectral analysis. It is the demand of the conservation-oriented and environmentally friendly modern society to…

Black tungsten wire means the tungsten wire that has not been processed by cleaning. And it was found that the “black” on the surface was formed by the adhesion of graphite and tungsten oxide. Graphite acts as a lubricant for the drawing process. Tungsten oxide on the surface is generated using natural gas or electricity to heat the tungsten wire. The cleaned black tungsten wire, i.e., tungsten wire, has the characteristics of good electrical and thermal conductivity, high melting point…
