Uses
Uses & Benefits
  • Terbium salts are used in optical devices like laser devices.
  • Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
  
  • Aluminum is used in a various products; for example, cans, foils, kitchen utensils, window frames, beer kegs and aero plane parts, automobile parts, etc.
