Metal aluminium is erosion strongly resistant. This basically happens, because, through the metal exposure to the atmosphere, a thin, superficial, invisible oxide layer is instantaneously formed, impeding its further erosion (passivation phenomenon):

 

Characteristic Properties and usage examples:

Low specific gravity (2,7g/cm3) in combination with resistance Means of Transportation
Erosion Resistant Shipbuilding, Building Construction
Very good thermal and electrical conductivity Electric power distribution conductors, household articles
Microorganisms & light impenetrable Packaging – Pharmaceutical Industry
Non-magnetic material Electronic Equipment
Very good reflectivity response in combination with its low weight rescue blankets
Ductile and malleable Suitable for a wide range of uses
100% recyclable Environmental Protection

Anodising is a technical method of aluminium surface processing which makes it more resistant to erosion in harsh weather conditions e.g. in seaside areas.

Through anodising, aluminium surface is reshaped and an oxide layer is artificially formed. Since the process takes place under absolutely controlled conditions, this oxide layer is really compact and hard. Given that this layer is already oxide, when exposed to the atmosphere, it does not erode and thus the metal is protected. As a result, anodised aluminum is established as the strongest metal with great resistance to erosion.

As you may observe in the shape above, the basic difference between anodising and electrostatic painting is that during anodising, whose thickness ranges from 10-25 μm (20-25μm of which are also called sea anodising), the anodising layer penetrates into the metal and practically does not change its dimensions. Electrostatic painting overlays the metal, increasing thus its thickness.

In any case, anodizing constitutes the safest processing method in order to increase metal resistance in harsh weather conditions. Our long-standing experience (more than 60 years now) has proven that anodising is a much safer choice in comparison with modern electrostatic painting method.

The best way to understand this is by using a magnet. Aluminium is not magnetised and therefore it cannot be oxidised, as opposed to iron which is magnetised and therefore it can be oxidised.

Pay attention, however, to some stainless amalgams which are not magnetized but are oxidised. E.g. Amalgam 304 is not magnetised, but it is oxidised, something uknown to most people who generally consider stainless material as the best one.
