Uses
Uses & Benefits
  • Tin-niobium alloy is used for producing superconducting magnets.
  • Tin salt known as a tin II chloride, it is used as a mordant and as a reducing agent for dyeing calico and silk.
  
  • 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.
