Marine Grade Aluminum Plate Exporter
Marine grade aluminum plate exporter Haomei gain good market reputation by high quality marine aluminum 5052, 5083 and 5086. Marine aluminum plate is also the key direction of transformation and upgrading of many aluminum processing enterprises. Because marine grade aluminum plates are used in marine and ships and other fields, they have stricter process requirements and performance standards than other ordinary aluminum alloy products.
The selection principles of marine grade aluminum plate exporter are as follows:
1, It has high specific strength and specific modulus.
The structural strength and size of ships are closely related to the yield strength and elastic modulus of the material. Since the elastic modulus and density of aluminum alloys are roughly the same, the addition of alloying elements also has little effect. Therefore, increasing the yield strength within a certain range will reduce the yield strength of the ship. The boat structure is strong. It is often difficult for high-strength aluminum alloys to have excellent corrosion resistance and weldability at the same time. Therefore, marine grade aluminum alloys are generally medium-strength, corrosion-resistant and weldable alloys.
2, Excellent welding performance.
At present, the automatic argon arc welding method is mainly used in ships. Good weldability means that the tendency of cracks formed during welding of aluminum alloys is smaller, which means that marine grade aluminum plate alloys must have good welding crack resistance. Because under shipbuilding conditions, the lost welding performance cannot be restored by heat treatment again.
3, Excellent corrosion resistance.
Ship structures are used in harsh seawater media and marine environments. Therefore, corrosion resistance is one of the main signs of marine aluminum alloys.
4, Aluminum alloy has good cold and hot forming properties.
Because the shipbuilding has to undergo multiple treatments such as cold processing and hot processing, the marine aluminum alloy must be easy to process and shape, without cracking defects, and still meet the requirements of strength and corrosion resistance after processing.
