Uses
Uses & Benefits
  • Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
  • Thi metals alloy is used in magnate as it is resistance to high temperature.
  
  • Silver is mainly used for Jewelry and show piece.
  • It is used for manufacturing high quality mirrors due to its reflectivity property.
