Facts
Interesting Facts
  • Dysprosium acts stable in air at room temperature.
  • Dysprosium behaves very much like paramagnetic metal.
  
  • It is found in copper ores and from the crust of the earth.
  • It is the most malleable and ductile metal.
  • Gold alloys are used in Dentistry as fillings, crowning, clips, etc. It is also used as an artificial limb joints.

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.
  
  • Gold metal is mainly used for Jewelry, bullion, coinage, etc.
  • It is used in the art, decoration, ornaments, etc. It is also used for electroplating process.
