Both aluminum and magnesium are found in abundance on Earth, but only aluminum is really used to produce consumer electronics and other important products. That’s because aluminum-based alloys are cheap to produce and the metal offers high structural integrity and even improves fuel efficiency when used in planes.
Magnesium is even lighter than aluminum, which means it could become the metal of choice for certain products. But the problem with magnesium is that, by itself, the metal is pretty soft, though that might change in the future thanks to the work of scientists from UCLA who have developed a method to increase the strength of magnesium.
