3 Uses
3.1 Uses & Benefits
  • Magnesium aluminum alloy improves the mechanical strength and welding characteristics and hence it is used in aeroplane and car manufacturing.
  • It is also used to remove sulfur from the molten iron and steel.
  • It is a highly radioactive metal; and sometime Radium-223 is used to treat prostate cancer.
  • It is used in luminous paints.
