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.
  
- 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.
