![]() This type of corrosion is discussed in more detail here but it accounts for the largest number of aluminium corrosion problems. ![]() Naturally it will vary greatly from location to location depending on air pollutants and the metals proximity to natural bodies of water like lakes and oceans. This is a particular problem in the export packaging world where shipping goods worldwide can be hazardous due to different climates and atmospheric conditions. It accounts for most damages and product defects by weight. Sometimes this hazard is referred to as damp, wet or dry corrosion. This understanding can often make the difference in discovering an effective aluminium corrosion treatment.īy far the most common culprit it is also the oldest being the result of exposure of metals to increased humidity and moisture. Most noble metals will be vulnerable to corrosion. You may also seen the reaction between water and aluminium, high amounts of energy are released. It’s the main ingredient in of choice in the space shuttles propulsion rocket fuel. This can even be considered early stage corrosion but this layer has a ‘protective’ quality preventing any further rusting of the metal in it’s environment.īack to ALuminium being a reactive metal, which it is. On the one hand raw aluminium will interact with oxygen and water to form a consistent surface oxide layer. ![]() This said it can also be considered a passive metal, explained by the contradictory processes that occur during a reaction. So what is Corrosion? Corrosion by definition can be considered a chemical reaction that occurs in metal.įor this article the metal in question is aluminium, a very reactive metal with a unique set of electromechanical properties.
