Uses
Uses & Benefits
- It is use for coinage and bullion.
- Most of copper element is used in manufacturing electrical and electronic equipments such as wirings and components. It is also used in construction and industrial machine.
- Strontium metal is used to producing ferrite magnets as well as refining zinc.
- By-product of nuclear reactors called Strontium-90 is a radioactive isotope; it is absorbed by tissues and destroys bone marrow and cancer growth.
