Marine aluminum plate for boat is one of the new categories of aluminum alloy products, and it is also an important industry application for the aluminum product suppliers. Marine aluminum plates are used in marine ships and boats and other fields, and thus have more stringent technical requirements and functional specifications than other common aluminum alloy products. As we all know, the marine grade aluminum has 5000 series as the typical alloy such as 5083 aluminum and 5086 aluminum.
The standard for marine aluminum plate can be divided into four areas.
1, With high specific strength and specific modulus
The structural strength and scale of the vessel are closely related to the yield strength and elastic modulus of the data. Since the elastic modulus and density of the aluminum alloy are generally the same, the addition of alloying elements has little effect. Therefore, the improvement of the yield strength within a certain range is effective for reducing the ship’s structure. High-strength aluminum alloys are difficult to have excellent corrosion resistance and weldability together. Therefore, marine grade aluminum sheets are usually medium strength, corrosion resistant weldable alloys.
2, Excellent welding function.
The first choice for ships is the active argon arc welding method. The outstanding weldability means that the aluminum alloy has small tendency to crack when welded, that is the aluminum plate for boat has excellent welding crack resistance.
3, Excellent corrosion resistance
The use of ships and boats are in the harsh seawater marine environment, therefore, corrosion resistance is one of the primary symbols of marine aluminum plate alloys.
4, Outstanding cold and hot forming function
Due to the ship is processed by cold processing and hot processing, so the marine aluminum plate for boat must be easy to process, no crack defects, and still meet the corrosion resistance requirements after processing.
