  • Description

Tungsten Rhenium Electrode

Uses: Tungsten-rhenium alloy electrode 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.


Due to its excellent high temperature properties, W-Re alloy has different applications in parts and temperature measurement. It mainly includes:


1. Aerospace: tungsten rhenium alloy is applied to high temperature parts and temperature measurement system in aerospace field.


2. Semiconductor industry: due to its excellent physical properties, tungsten rhenium alloy is used for high-temperature parts and components of equipment in semiconductor industry, such as heating device, temperature measuring device, etc.


3. Industrial furnace: high temperature parts and temperature measuring device.


4. Welding industry: friction stir welding joint.

Tungsten rhenium alloy has better mechanical properties and ductility than pure tungsten, and high resistivity, so it has better processability and weldability. The tungsten rhenium alloy containing 3% rhenium can be used as the core metal for the filament, grid wire and direct heated cathode of electronic tube. The tungsten rhenium alloy containing thorium, namely thorium tungsten rhenium alloy, is used as the direct hot cathode of large-scale emission tube. Its performance is better than that of thorium tungsten cathode, and it is not easy to deform at high temperature.


Performance characteristics: tungsten rhenium electrode has high melting point, low vapor pressure, good seismic resistance, excellent strength, toughness and oxidation resistance at high temperature.

Application field: tungsten rhenium rod is mainly used in aerospace field and other high temperature field parts, friction stir welding joints, etc.


The preparation of W-Re alloy mainly includes powder metallurgy and smelting. Because of the high yield and low cost of the alloy prepared by powder metallurgy, the powder metallurgy is mainly used to produce W-Re alloy at present. The P / M process of W-Re alloy is as follows: preparation of pre alloyed powder - Compact - sintering - pressure processing.

Tungsten rhenium alloy can be processed into plates, sheets, wires, wires and rods, which can be used in high temperature structural parts (nozzles, nozzles, heat shields, etc.), elastic components and electronic components in aerospace and aviation. With the wide application of tungsten rhenium alloy, the requirements for its performance are more and more high, and the development of ultrafine / nanocrystalline tungsten rhenium alloy is gradually put on the agenda.
