Uses
Uses & Benefits
  • The main use of this metal include nuclear fuel which is used to generate electricity yin nuclear power stations.
  • Synthetic elements like transuranium are made from Uranium metal.
  
  • It has corrosion resistance and hence it is used to plate other metals.
  • Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
