3 Uses
3.1 Uses & Benefits
  • Alloys of Rhenium are used as an electric contact material. It can resist withstand arc corrosion.
  • Its catalysts are used in hydrogenation of fine chemicals. Its Alloy with nickel is used to produce turbine blades.
  • It has a tendency to get tarnished in the open air, but when alloyed with elements like erbium, vanadium, its hardness levels decreases.
  • Its compounds like Erbium oxide is used in safety glasses of welders and metal workers.
