How does aluminum avoid corrosion?
Aluminum forms a 1 nm (or sometimes slightly thicker) layer of aluminum oxide on its surface when it is exposed to air. Even though aluminum is reactive this oxide layer prevents the actual aluminum making contact with other elements which it could react with. In this way aluminum avoids reaction and corrosion. This is a particularly important feature for aluminum is its outdoor uses where being resistant to weathering is essential. If the layer breaks it immediately reforms when the aluminum is next in contact with oxygen. Why is aluminum used so much in transport? Aluminum is a low density material which gives it its lightweight property. When mixed with other elements in alloys it is also very strong. This unique combination of strength and weight is essential for the transport industry. As Force = Mass x Acceleration, the bigger the mass the more force will be needed to achieve a certain acceleration. This means that using aluminum is transport vessels saves money on fuel, allows m
