Performance Standards for Marine Aluminum Plate
- High specific strength and specific modulus: The structural strength and size of the ship are closely related to the yield strength and elastic modulus of the material. Since the elastic modulus and density of aluminum plates are basically the same, the addition of alloy elements has little effect, so increasing the yield strength within a certain range is beneficial to lightening the ship structure.
- Excellent welding performance: Good weldability can make the aluminum plate less prone to cracks formed during the welding process, that is, the aluminum plate should have good welding crack resistance, because the lost welding performance cannot be restored through reheat treatment under shipbuilding conditions.
- Good corrosion resistance: Ship structures need to be used in harsh seawater media and marine environments, so corrosion resistance is one of the main signs of marine aluminum plates.
- Have good cold and hot forming properties: Since ship manufacturing requires cold and hot processing, marine aluminum plates must be easy to process, have no crack defects, and still meet strength and corrosion resistance requirements after processing.

Marine Aluminum Sheet Plate Applications
5052, 5083, 5086 and 6061 marine grade aluminum sheets are often used on ship decks. There are very high requirements for corrosion resistance, water resistance, anti-skid, and wear resistance.
5052 and 5083 aluminum plates are the two main marine aluminum plates used in yacht and shipbuilding.
5052H32, 5086 and 6061 are the main alloys for aluminum plates used in fishing boats that are safer and more economical.
5083, 5052, and 5a03 marine grade aluminum plates are often used to manufacture ship chimneys due to their good strength, excellent welding performance, and strong corrosion resistance.
Aluminum Plate for Ship Deck
The ship deck refers to the large plate frame above the inner bottom plate that covers the inner space of the ship or divides it into layers. Mainly composed of aluminum plate and stock price. The deck is divided into upper and lower parts: the upper deck is the uppermost continuous deck from bow to stern; the lower deck is the deck at the upper bottom of the ship. The space between the upper deck and the lower deck is called the interdeck compartment, and the space between the lower deck and the bottom of the ship is called the cabin.
The main alloys of aluminum plates for decks are: 5052, 5083, 5086 and 6061, and most of them use aluminum diamond plates. The main specifications are as follows:

Aluminum Ribbed Plate for Ships
Aluminum ribbed plate mainly act on the hull structure and key parts to strengthen and support.
Marine Grade Aluminium Sheet Surface Treatment
There are two commonly used surface treatment methods for marine aluminum plates: anodizing and color coating. Both can effectively improve the corrosion resistance of aluminum, extend its service life, reduce maintenance costs, and enhance the aesthetics of the hull.
Anodizing: By thickening the oxide film on the surface of the aluminum plate, a hard coating is obtained to improve corrosion resistance. Marine 5000 series and 6000 series are best suited for anodizing.
Color coating: Color coating can enhance the adhesion between aluminum plate and paint. To further reduce the contact between aluminum and the external environment, commonly used ship coatings include polyurethane coatings, epoxy coatings, etc.
