3 Uses
3.1 Uses & Benefits
  • Aluminum is used in a various products; for example, cans, foils, kitchen utensils, window frames, beer kegs and aero plane parts, automobile parts, etc.
  • 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.
