Is aluminum man made or natural?

Answer 1

Aluminum is a natural metallic element signified by [AL] in the Periodic Table. While it is a natural element it is mostly found as an oxide or silicate which means it must be processed before pure aluminum is obtained. Most aluminum used is actually an alloy consisting of aluminum along with various other components.
Man-made, of course.

Aluminium is extracted from bauxite (aluminium oxide mainly) by the Hall-Heroult process.

Answer 2

Aluminum is a naturally occurring element found in the Earth's crust. However, the extraction and production of pure aluminum metal from its ore bauxite involve industrial processes, making it a man-made material in its refined form.
