Aluminum is a ductile corrosion resistant metal that was first produced in an impure form in 1825. It is lightweight, non-magnetic and moderately soft. The metal is durable and seen in colors ranging from silver to dull grey. In 1850’s aluminum was used to make figurines, ornaments, and plaques.
How do you describe aluminum?

Is aluminum an alloy?
Aluminum is a chemical element while an alloy is a mixture of several chemical elements. Hence, the key difference between alloy and aluminum is that an alloy is a substance formed from mixing two or more different chemical elements whereas aluminum is a chemical element that we can find on earth’s crust as a metal.
