Aluminum Sheet for Ship are used in the marine vessels field, and have more stringent process requirements and performance standards than other common aluminum alloy products.
Aluminum Sheet for Ship
First, there is a 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 data. Since the elastic modulus and density of the aluminum alloy are substantially the same, the addition of alloying elements has little effect. Therefore, the yield strength within a certain range is effective for reducing the structure of the ship. High-strength aluminum alloys are often difficult to have both excellent corrosion resistance and weldability. Therefore, marine grade aluminum alloys are generally medium-strength, corrosion-resistant weldable alloys.
The second is excellent welding performance. At present, the main method used in the ship is the automatic argon arc welding method. Good weldability means that the tendency of marine grade aluminum alloy to form cracks during welding is small, that is, marine grade aluminum alloy should have good welding crack resistance. The lost weldability cannot be restored by reheating under shipbuilding conditions.
The third is excellent corrosion resistance. the ship is used in several harsh seawater media and marine environment. Therefore, corrosion resistance is one of the main signs of marine grade aluminum alloy.
Fourth, aluminum alloy casement window have good cold and hot forming properties. Because the ship is manufactured by cold processing and thermal processing, the marine grade aluminum alloy must be easy to form, can’t produce crack defects, and can still meet the strength and corrosion resistance requirements after processing.
Aluminum sheet for ship materials are more stringent. 5083, 5086, 5454, 5754, and 6061 are currently used. In practical applications, the advantages of marine aluminum alloys are obvious. Firstly, the specific gravity is small, which can reduce the weight of the ship, save energy and increase the load; secondly, the 70-branched aluminum alloy doors and windows have good corrosion resistance, reduce the cost of oiling and extend the service life; thirdly, the welding and processing formability are good. It is conducive to post-processing. Thicker aluminum scrap is easy to recycle, can be recycled.
Henan Mingtai Aluminum Industry Co., Ltd. is China's leading manufacturerof aluminum sheet for ship. It is one of the top ten aluminum plate and foil processing enterprises in the country with an annual production capacity of 750,000 tons. It is specialized in supplying marine grade aluminum plate, which sold well all over the world.
Mingtai marine grade aluminum plate is mainly made up of 5 series and 6 series aluminum alloy. 5083 aluminum plate has obtained the ABS American Classification Society certification, represented by 5083, 5086 aluminum plate, 5754 aluminum plate and other products. It has entered the world shipbuilding market, mainly used in deck of ships, engine pedestal, ship side and bottom plate, or other components.
1. The low density, high strength, high rigidity and corrosion resistance of aluminum make the weight of aluminum ships less than 20% compared with ships constructed of steel or other alloy materials. This can reduce the weight of the ship and reduce energy consumption. In addition, the high toughness, corrosion resistance and weldability of Mingtai marine grade aluminum alloys offer the possibility of strict ship type production. At the same time, Mingtai aluminum alloys ship board can resist the corrosion of atmospheric, steam, water and other media in the marine climate for a long time, durable and more economical, is very enconomic.
2, advanced production equipment - to create the excellent quality of Mingtai marine grade aluminum plate. Mingtai Aluminum has advanced equipment for the production of marine grade aluminum plate. Such as roughing mills, finishing mills, quenching furnaces, straightening machines, polishing machines, etc.
3, strong processing capacity - Mingtai marine grade aluminum plate with an annual output of 200,000 tons to help customers seize the market.
4, the authoritative international certification - for the Mingtai quality marine grade aluminum plate offer escort.
