Uses
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.
  
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
