Uses
Uses & Benefits
  • Californium metal has a very strong neutron emitter. It is used as a metal detector.
  • It also used as an identifier to check Water and oil layers in oil wells.
  
  • Magnesium aluminum alloy improves the mechanical strength and welding characteristics and hence it is used in aeroplane and car manufacturing.
  • It is also used to remove sulfur from the molten iron and steel.
