     Magnesium is used in photography, flares, pyrotechnics and incendiary bombs. As it is one-third less dense than aluminium, its alloys are useful in aeroplane and missile construction.
     It improves the mechanical, fabrication and welding characteristics of aluminium when used as an alloying agent.
     Magnesium hydoxide (milk of magnesia), sulfate (Epsom salts), chloride and citrate are used in medicine.
     Grignard reagents, which are organic magnesium compounds, are important commercially.
