Rich Marine Grade Aluminum Products

What is marine grade aluminum?

Marine-grade aluminum possesses various beneficial characteristics and is highly suitable for the construction of maritime vessels and equipment. When exposed to water and air, aluminum forms an aluminum oxide coating that helps protect the metal from further corrosion, making it well-suited for marine applications.

The selection of aluminum alloys for marine environments is crucial. For instance, alloys from the 3000 series are prone to rapid oxidation and are not suitable for prolonged exposure to water. Instead, it's essential to use marine-grade aluminum alloys such as those from the 5000 or 6000 series when dealing with aluminum alloys that will come into contact with water or moisture from water.Quick Quote

Marine grade surface treatment: aluminum anodizing, coating, cathodic protection

Anodizing

Anodizing is a process that forms an aluminum oxide film on the surface of aluminum through electrolysis, enhancing its corrosion resistance, wear resistance, conductivity, and other properties. This method has excellent anti-corrosion effects, making it especially suitable for ships in seawater environments. However, the process is complex, costly, and not suitable for complex-shaped parts.

Coating

Coating involves applying one or multiple layers of coating on the surface of aluminum to block its contact with corrosive media, thereby providing corrosion protection. This method is simple, cost-effective, and allows for the selection of different types of coatings based on specific anti-corrosion requirements. However, the adhesion between the coating and the substrate is limited, making it prone to peeling, and its corrosion resistance is not as good as anodizing.

Cathodic Protection

Cathodic protection involves applying external current or sacrificial anodes to make the aluminum surface act as a cathode, thereby inhibiting anodic corrosion reactions. This method provides excellent anti-corrosion effects, long-term protection for the aluminum substrate, and does not affect its conductivity and thermal conductivity. However, the process is complex, costly, and requires regular maintenance.
