The aerospace industry has long recognised the benefits to be gained of weight reduction by utilising high performance sand cast and forged magnesium alloys for the production of critical components.
Magnesium alloys are extensively used for a range of helicopter transmission casings. Elektron®RZ5 (ZE41) is an alloy specified for applications operating up to 150°C due to its excellent castability and good mechanical properties.
In the aeroengine industry, magnesium alloys are being used successfully in both civil and military aircraft. Civil applications include intermediate casings for the Tay (Elektron®RZ5/ZE41) engines and gearboxes for the RB211 (Elektron®ZRE1/EZ33), Tay (Elektron®ZRE1/EZ33) and BR710 (Elektron®RZ5/ZE41) engines. Military aircraft, including the F16, Tornado and Eurofighter Typhoon, capitalise on the lightweight characteristics of magnesium alloys for transmission casings.
