To obtain greater ductility and a lower brittle-to-ductile transition temperature, tungsten is alloyed with rhenium. Moreover, tungsten-rhenium has a higher recrystallization temperature and better creep resistance.
The WRe standard compositions are used as material for thermoelements in applications of over 2000 °C. This material is also used in the aviation and aerospace industries.
