Aluminum - FSB North America FSB North America

Aluminum is the most commonly occurring metal in the Earth’s crust. First isolated in 1825, Aluminum has been used in many ways over the years. Napoleon used aluminum plates during French state dinners for distinguished guests while “rank and file” guests were only served on gold or silver plates.

Corrosion of Aluminum and Its Alloys: Forms of …

This contradictory nature is explainable because nascent aluminum reacts with oxygen or water and forms a coherent surface oxide which impedes further reaction of aluminum with the environment. Corrosion is the chemical reaction of a metal, in this case aluminum, with its environment, which leads to the deterioration of the properties of metals, aluminum in this case.
