Engines
Luxfer MEL Technologies alloys are used on many aircraft engines from producers such as GE, Honeywell, Rolls-Royce and Pratt & Whitney. Our Elektron® 21, and Elektron® WE43, alloys are found in transmissions and structures on jet engines. New, highly efficient turboprop engines incorporate these alloys in many structural parts and in integrated reduction gearboxes, including those found on Pratt & Whitney PW-100/150 series and PT-6 engines used on many commuter aircraft.
Elektron® magnesium alloys are also used structurally or as casting materials for many ancillary aircraft components, including constant speed drives (CSDs), integrated drive generators (IGDs) and auxiliary power units (APUs).
Virtually all new U.S. and many European fighter aircraft contain Elektron® alloys in their power systems. Since fighter engines run at very high temperatures, our advanced, heat-resistant Elektron® WE43 and Elektron® 21 alloys are used almost exclusively in auxiliary power units (APUs), constant speed drives (CSDs), airframe-mounted accessory drives (AMADs) and engine gearboxes. Fighter aircraft using these alloys include the F-22, F-35, F-16 upgrades and Eurofighter Typhoon.
Elektron® 21 is a new high strength fully heat treatable magnesium based casting alloy for use at temperatures up to 200˚C.
This lightweight magnesium alloy has excellent corrosion resistance characteristics and castability.
Elektron® RZ5/ZE41 is a well proven lightweight magnesium casting alloy containing zinc, rare earths and zirconium.
Used in the T5 condition, this high strength magnesium alloy is ideal for high integrity castings operating at ambient temperatures or up to 150˚C. In addition to displaying excellent casting characteristics, the alloy is both pressure tight and weldable.
Elektron® WE43B is a high strength magnesium based casting alloy developed and patented by Luxfer MEL Technologies for use at temperatures up to 300˚C.
This alloy system maintains its good mechanical properties at elevated temperatures, without the use of either silver or thorium. The alloy is stable for long term exposure up to 250˚C. Elektron® WE43B has excellent corrosion resistance characteristics.
