Corrosion resistant aluminum is usually made with special alloys and treatments to ensure excellent corrosion resistance in the marine environment. It is also known as marine grade aluminum because it can be used in sea water and boat building.

Among corrosion resistant aluminum alloys, the following alloys are widely recognized for their excellent corrosion resistance:

- 5000 series aluminum alloys (e.g. 5052, 5059, 5083, 5086, etc.):

These aluminum alloys contain mainly magnesium and have excellent corrosion resistance, making them particularly suitable for marine environments and wet climates. 5083 marine aluminum alloy performs particularly well in extreme environments and is commonly used in ships and marine structures. It is commonly used in hulls, cabins and other parts of ships.

- 6000 Series Aluminum Alloys (e.g. 6061, 6082, 6063, etc.):

These aluminum alloys contain magnesium and silicon and have high strength, although the corrosion resistance is not as good as the 5000 series, but after anodic oxidation treatment, the corrosion resistance can be significantly improved. 6061 marine aluminum alloys are widely used in the fields of construction, transportation and aviation. It is suitable for ship structure, cabin, mast and other parts.

- 7075 Series Aluminum Alloy:

Although aluminum alloy 7075 is known for its high strength and its relatively low corrosion resistance, its corrosion resistance can be improved under certain conditions by appropriate surface treatment (e.g. anodizing). These aluminum alloys have excellent strength and hardness, as well as a certain degree of corrosion resistance, and are suitable for use in marine engineering, ship construction and other fields.

These corrosion resistant aluminum alloys are usually subjected to special treatment processes, such as anodizing and spraying for corrosion protection, to enhance their corrosion resistance. When choosing super corrosion-resistant marine grade aluminum plates, you need to choose the right type of aluminum alloy and treatment according to the specific use environment and requirements.

Overall, 5000 series aluminum alloys (especially 5083 and 5086) are often considered the best corrosion resistant aluminum alloys for marine and other corrosive environments. When selecting a suitable aluminum alloy, in addition to corrosion resistance, other performance requirements such as strength, machinability and weldability should also be considered.
