Solution for Seawater

Aluminium Bronze is a corrosion resistant metal in sea water. Aluminium Bronze alloys consist mainly of copper to which 9-14% aluminium is added. Other metals such as iron, manganese and nickel can serve as additional alloying elements to further enhance certain capabilities such as sliding properties.

Aluminium Bronze owes its excellent corrosion resistance to its protective passive film. Compared to other metals, this film forms very quickly and heals quickly in the event of injury. This protective layer expresses itself in its typical brownish colour. Although this does not look very aesthetic from the outside, this film protects the metal it encloses. The aluminium is mainly responsible for this film. It reacts easily with the oxygen in its environment and forms this insurmountable barrier. Thanks to these properties, the material is used especially in the marine industry.

Although this external protective film does not aesthetically make a good impression, it is not worth cleaning the Aluminium Bronze. This is because the alloy loses its corrosion resistance for a short time and the chemical reaction causes damage to the Aluminium Bronze, which can then possibly be restricted in its functionality. Therefore, they do not have to be specially cleaned and require generally very little maintenance.
