It is widely
used as filaments for mass spectrographs and ion gauges.
Rhenium-molybdenum alloys are superconductive at 10 K.
also used as an electrical contact material because it
has good wear resistance and withstands arc corrosion.
Thermocouples made of Re-W are used for measuring
temperatures up to 2200C, and rhenium wire is used in
photoflash lamps for photography.
Rhenium catalysts are exceptionally resistant to
poisoning from nitrogen , sulfur , and phosphorus , and
are used for hydrogenation of fine chemicals.
