Rhenium’s characteristics of high electrical resistivity over wide temperature ranges, plus a low vapor pressure make it a good choice for filaments in mass spectrometers.
Another major use of rhenium is as a catalyst in the crack distillation of petroleum products.
It is most commonly used as an alloying agent with other refractory metals to improve their properties. When combined with molybdenum it makes the ideal candidate for heat chokes, cathode stem supports and other similar parts due to its ductility, weldability, formability and strength.
