Most Abundant Metal in the Earthâs Crust. Aluminium â Itâs the most abundant metal in the Earthâs crust, yet it entirely escaped our notice until 1825. You might say it was hidden in plain sight. Aluminium is a highly reactive metal, meaning it readily undergoes chemical reactions with other elements and compounds to form different substances. As a result, nearly all of the naturally occurring aluminium atoms on Earth ended up tucked away in the molecules of more than 270 different minerals, including gemstones like emeralds and rubies.
