W-3Re/W-25Re, W-5Re/W-20Re, W-5Re/W-26Re, W/W-26Re, Commonly used for tungsten sapphire or sapphire tungsten-rhenium alloy wire for single crystal sapphire binding Model: W-25Re, diameter 0.5mm
Model: WRe3 / 25, WRe5 / 26, WRe5 / 20
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.
