To obtain greater ductility and a lower brittle-to-ductile transition temperature, we alloy our tungsten with rhenium. Moreover, tungsten-rhenium has a higher recrystallization temperature and better creep resistance. We use the WRe standard compositions – WRe5 and WRe26 – as material for thermoelements in applications of over 2 000 °C.

Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten alloys are produced with up to 27% of Re, which is the solubility limit.
SUPERPLASTICITY IN TUNGSTEN-RHENIUM ALLOYS by M. Garfinkle, W. R. Witzke, and W. D. Klopp Lewis Research Center SUMMARY The tensile properties of binary tungsten-rhenium alloys containing up to 33-atomic percent rhenium were determined at temperatures from 78° to 3630° F …
The density of rhenium is among the highest of all metals and somewhat higher than for tungsten. However, the alloy content of rhenium is rather limited meaning that tungsten-rhenium wire has a density that is almost the same as for tungsten wire. We only offer Tungsten wire alloyed with 3% rhenium. Tungsten-Rhenium Wire dimensions. Luma ...
Rhenium is a rare metal with unique properties that make it ideally suited for today's most powerful engines and critical chemical reactions. Eagle Alloys is a premier rhenium metal supplier providing rhenium in both its pure form and most popular alloys.
Tungsten-Rhenium (WRe) Historically Tungsten 25% Rhenium alloy has been produced into wire for the thermocouple market, but recent demands for high temperature structural components have forced the development of novel processing techniques for Tungsten-Rhenium and Tungsten-Rhenium with hafnium carbide.
Addition of Re to tungsten raised the temperature of incipient recrystallization of tungsten VCh wire by 200–400°C, depending on the rhenium content. 3. Rhenium improved the strength and ductility of tungsten in the 20–3000°C range.
