Elektron - Model 43 -Aircraft Interiors Extrusion Alloys

Weight reduction initiatives are being driven by higher fuel costs, greater efficiency and reductions in CO2 emissions for environmental reasons. The weight advantage over aluminium is becoming increasingly important. So too the ease with which to produce complex critical structures and reduce cost. Magnesium is an attractive alternative in the field of advanced materials for aircraft systems of today and the future.

Elektron® 43 lightweight magnesium extrusion alloy developed by Luxfer MEL Technologies, passed rigorous tests conducted by the U.S. Federal Aviation Administration (FAA) Fire Test Working Groups, which subsequently lifted long-standing restrictions on the use of magnesium alloys in commercial aircraft interiors. By following the guidelines Elektron43 alloy is setting the standard for the reintroduction of magnesium into aircraft interior.
