Flame Resistant Magnesium Alloys

Up to now, the applicability of magnesium alloys was limited due to its light flammability. Reason therefore is the oxidation tendency of the alloys. In a research project, LKR scientists managed it to develop magnesium alloys, which show the capability to self-extinguish in case of a fire.

  • Increased flammability resistance and good mechanical properties
  • Flammability resistance certified acc. to the Federal Aviation Administration
  • Remarkable cheaper than alloys with comparable flame resistance
  • Processability in various casting processes (e.g. high pressure die casting, Thixomolding)

BEFORE: MAGNESIUMALLOYS AZ91 AND AM60
