Tungsten Rhenium Wire,Tungsten

Made of tungsten alloyed with 3%, 5%, 25% or 26% rhenium, W-Re alloys become more ductile and machineable. And due to the good electrical properties, they are widely used as high temperature thermocouple materials. As the most common material, tungsten rhenium wire is used for the production of heaters for dispenser cathodes.

Selective Laser Melting of Tungsten

Additively manufactured tungsten-rhenium alloys have been compared with pure tungsten in terms of their volumetric density, cracking behavior, microstructure, and hardness. The compositions W-5 wt.%Re and W-25 wt.%Re were explored. Increasing the rhenium content led to an increasing percentage of the theoretical density, with a maximum of 97.6% achieved with 25 wt.% Re.

Tungsten Rhenium Alloy

Rhenium improves the properties of tungsten. Tungsten rhenium alloys are more ductile at low temperature while stability under high temperature is improved as while. The effect increases with the rhenium concentration and usually W Re alloys are produced up to 26% of Re. The cost of these materials is relatively lower compared to noble Pt and Rh.

Tungsten-rhenium (W-Re) alloys have excellent high-temperature properties due to the solution strengthening of Re. However, the best strengthening position of Re in W-Re alloy at high temperature is not clear.

Tungsten-Rhenium Alloy – Thermal Conductivity. Thermal conductivity of Tungsten-Rhenium Alloy is 70 W/ (mK). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance's ability to transfer heat through a material by conduction.
