Uses
Uses & Benefits
  • 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.
  
  • 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.
