There are many different types of aluminium alloy anode currently available. These are characterized by the addition of impurities such as zinc and indium. The exact contents of these impurities is important, particularly in the cases of iron and copper which should not exceed 0.15% and 0.005% respectively.
The main characteristic of an aluminium anode is the high nominal electrical capacity, which is three times higher than the same mass in zinc. By using aluminium in structures instead of zinc anodes, you require significantly less aluminium anodes and it is therefore easier to manage their underwater installation or subsequent replacement. Aluminium anodes are frequently used in industrial sectors, such as offshore platforms or pipeline systems, where a long term protection is required, usually over 15 years, and where anodes replacement is expensive and difficult.
They are also used in the commercial sector, such as cargo ships, tankers or cruisers or where there are long periods between planned dry dock activity. They are recommended for hulls which remain permanently in water ( such as barges, house boats etc.). More recently, many outboard engine manufacturers switched to using aluminium anodes due to the growing objection to the continued usage of zinc anodes in some parts of the world. Cadmium which is a material always present in zinc alloy, can be considered harmful to the sea.
