Aluminum is reactive and will react spontaneously with water and/or air to form aluminum oxide. Aluminum oxide, Al2O3, forms a stable passive layer that protects aluminum from corrosion or further oxidation. This layer is about 4 nm thick and will provide corrosion protection as long as this oxide layer is stable.
Aluminum is resistant to breakdown because it forms a strong chemical bond with oxygen. This is why aluminum often becomes discolored or dull in appearance. To clean aluminum, acid needs to be used in order to neutralize the buildup of oxidation.Follow these steps for using acid wash on aluminum products.luminum is resistant to breakdown because it forms a strong chemical bond with oxygen.
