Copyright © 2020 Multiply Media, LLC. Rhenium-molybdenum alloys are superconductors. Rhenium has the distinction of being the last stable, naturally occurring element that was discovered.
These alloys found important applications in industry that resulted in a great demand for the rhenium produced from the molybdenite fraction of porphyry copper ores. Rhenium is used in superalloys, such as CMSX-4 (2nd generation) and CMSX-10 (3rd generation).
 Rhenium has 33 known radioisotopes.
It is also the third densest element. Iridium: Discovered in 1803 by Smithson Tennant 78.
