Uses
Uses & Benefits
  • Currently known uses of Ununpentium metal are limited to research purpose only.
  
  • Magnets of Samarium cobalt alloy are stronger than that of Iron and hence, they are used in microwave application.
  • Samarium metal also used in optical lasers and infrared absorbing glasses and as a neutron absorber.
