Magnesium Facts

  • The primary uses of magnesium are in aluminum alloying, magnesium die-casting, desulfurization of steel, titanium production, and synthesis of special magnesium chemicals, automobiles, smartphones, batteries, etc.
  • Magnesium is the lightest of all commonly used structural materials, with a density ~78% lower than steel and ~35% lower than aluminum.
  • Magnesium alloys are 48-78% lighter than steel and 22-35% lighter than aluminum. In addition they have:
Magnesium Key Points
  • Today, cars, SUVs and pickup trucks contain only 5-7 kg of magnesium. However, the U.S. Automotive Materials Partnership estimates that, by 2020, 160 kg of magnesium will replace 227 kg of steel and 59 kg of aluminum per vehicle, leading to an overall weight reduction of 15 percent. This weight savings would decrease fuel consumption by 9-12%.
  • General Motors has developed a thermal-forming process and proprietary corrosion resistance treatment for magnesium sheet metal that will allow increased use of magnesium in vehicles as a high-strength alternative to steel and aluminum.
  • It is projected that the market for 99.9 wt. % pure magnesium would rise sharply if its global selling price could be lowered to a stable range of US$2,200-US$4200 per tonne.  In addition, if its longterm supply could be ensured and be produced in Canada (not China), increased customer confidence would likely result  in magnesium becoming an attractive alternative to steel and aluminum in fabricating parts for cars, trucks and armored military vehicles, etc.
