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.
  
- Its alloys are used in spacecraft, aircraft and ammunition industry.
- Its pipes are used in distillation plants, submarines, hulls of big ships, etc.
