G7/8 Cycle A - 1: Geology: Magnesium

Magnesium is the lightest structural metal used today, some 30% lighter than aluminium, and is generally used in alloys. Pure magnesium burns vigorously once molten, but magnesium alloys have higher melting points and are widely used in the automotive and aircraft industries.

The lightest common metal is magnesium. This element weighs one-third less than an equal volume of aluminum and is the eighth most abundant element in Earth’s crust. As a result, it has found extensive use in the aerospace industry.
