Aluminum is a post-transition metal and the 13th element on the periodic table and is a silvery-white metal. One surprising fact about aluminum is that it is the most common metal on the planet, accounting for more than 8% of the Earth's core mass, depending on which side of the Atlantic Ocean you live. The second-most used metal worldwide, after iron, it is the most prevalent metal naturally found on the planet and the most plentiful mineral on Earth after silicon and oxygen. Even though it has an aluminum concentration of up to 99%, it is primarily employed as an alloy.
Aluminium is one of the most important engineering materials of our time because it is lightweight, durable, and functional. Aluminium can be found in our homes, automobiles, trains and planes that transport us long distances, mobile phones and computers we use every day, shelves inside our refrigerators, and modern interior designs, but only 200 years ago, very little was known about this metal.
