All kinds of magnesium alloy are widely used for construction materials, electronic devices (mobile phones, laptop computers, cameras, and other electronic components), car devices (frames, hubcaps), Currently the use of magnesium alloys in aerospace is increasing, mostly driven by the increasing importance of fuel economy and the need to reduce weight. The development and testing of new magnesium alloys continues, notably Elektron 21 which has successfully undergone extensive aerospace testing for suitability in engine, internal and airframe components.
