Specification Brand : SINM BulletPoint1 : BulletPoint2 : ⚫+ W97Re3-W75Re25: The nominal composition of the positive electrode is tungsten-97% rhenium 3%, the nominal composition of the negative electrode is tungsten-75% rhenium 25%, the index number is WRe3-WRe25, abbreviation :W-Re3/25(ASTM index number :D) BulletPoint3 : Tungsten-rhenium alloy has better mechanical properties and ductility than pure tungsten, and high resistivity, so it has better processability and weldability. The main disadvantage of tungsten-rhenium alloy thermocouple is that the electrode is easily oxidized in the oxidizing atmosphere, and the bare wire is not suitable for continuous use in the oxidizing atmosphere BulletPoint4 : The maximum use temperature of Tungsten-rhenium thermocouple can reach 2800°C(5072℉), but the data dispersion will occur when it is higher than 2300°C(4172℉), so the use temperature is best around 2000°C(3872℉) BulletPoint5 : Tungsten-rhenium alloy thermocouple thermoelectric potential value and thermoelectric potential rate large output signal, can improve the measurement accuracy ExternallyAssignedProductIdentifier : 9331924639375 FinishType : Polished IncludedComponents : inc ItemForm : Coil ItemName : Tungsten-Rhenium Thermocouple Electrode, High Temperature Tungsten-Rhenium Alloy Wire, Diameter 0.5mm,W-Re Alloy WRe5-WRe26 and WRe39-WRe25 (500mm Length, W95Re5 -W74Re26) ItemPackageQuantity : 1 ItemShape : Round Rod ItemTypeKeyword : arc-welding-stick-electrodes Manufacturer : SINM Material : Tungsten NumberOfItems : 1 PartNumber : SINM Tungsten-Rhenium Thermocouple Wire ProductDescription : ProductSiteLaunchDate : 2023-09-14T15:38:08.566Z Size : 500mm Length Style : +W95Re5 -W74Re26
