Rhenium is a silvery-white metallic transition element. It is obtained as a by-product of molybdenum refinement. Rhenium-molybdenum alloys are superconducting. Rhenium has 35 isotopes. 2 of them are natural ones, 1 of which is stable.
Rhenium is mixed with tungsten or platinum to make filaments for mass spectrographs. Its main value is as a trace alloying agent for hardening metal components that are subjected to continuous frictional forces.
