Tungsten Rhenium Wire WRe5/26
Uses: Tungsten-rhenium alloy has good electrical properties, ductility and processability, and can be used for thermocouple temperature measurement in high temperature furnaces.
Applicable conditions: Use in vacuum, hydrogen, inert atmosphere, and its operating temperature range is 0 ~ 2300 ℃.
Non-uniform thermo-electromotive force: The non-uniform thermo-electromotive force of the entire coil (disk) of the positive or negative wire at 1200 ° C must not exceed 40-80 μV.
it is suitable for the temperature control system of energy, metallurgy, petroleum, chemical industry and scientific research departments. It is used for the connection between the cold end of the temperature measuring instrument and the temperature measuring instrument. The heat-resistant type adopts imported fluoroplastic insulation and sheath with excellent heat-resistant, waterproof, corrosion-resistant, acid-base resistant, chemical reagent resistant, wear-resistant, aging resistant and non combustion performance. The operating temperature is - 60-205 ℃
1. The positive electrode is WRe3; WRe5; the negative electrode is WRe25; WRe26
2. Temperature point: when the cold end is 0 ℃, the hot end temperature is 10010001200140016002000 ℃;
3. Uniformity: when the even wire is at 1200 ℃, the uneven electric potential of the single pole head and tail is ≤± 40 microvolt.
4. Flexibility: after stabilization and annealing, the even wires can be wound by themselves without fracture.
5. Supply status: even wires are supplied after stabilization annealing, and the color is silver white.
