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
afterwards: addition of calcium and yttrium
Certification
Passed flammability test according to FAA:
FAA Aircraft Materials Fire Test Handbook, Chapter 25; Oil Burner Flammability Test for Magnesium Alloy Seat Structure
Application
-
Arm- and backrests of aircraft seats
-
Housings and covers of aircraft engines
