What is marine aluminum plate?
Marine aluminum plate is the emerging market for R & D applications of aluminum products.
Performance and Application of 5 Series Marine Aluminum Alloy
At present, aluminum with its light weight, high hardness, corrosion resistance and other characteristics of the ideal shipbuilding field material. However, the development of any new thing is not smooth sailing, in the early stages of research, the application of aluminum ships have also undergone a heavy test. of better performance of aluminum alloy which has become a dynamic force of scientific and technological factors.
In 1891, the world's first ship of aluminum ships, its name is called Le Migron, by the Swede Alfred Nobel design completed, the initial carrying capacity of only 8 people, however, this is the first time the human aluminum Applied to the field of shipbuilding great attempt, it for the future aluminum, aluminum and other shipbuilding in the field of widespread use of the layoffs laid the foundation. of better performance of aluminum alloy which has become a dynamic force of scientific and technological factors.
In 1894, the Scottish shipyard Yarrow & Co exhibited a 58-meter-long aluminum torpedo ship. The torpedo ship for the Russian Imperial Navy, when the ship speed of 32 nautical miles, was broken at the time was the highest speed of the current record. A year later, the aluminum fleet 'Defender' won in America's most prestigious ship event, The America's Cup, and once again proved to the world the advantages of aluminum ships. of better performance of aluminum alloy which has become a dynamic force of scientific and technological factors.
However, due to the high cost of production of aluminum at that time, its promotion has been a certain obstacle. In addition, aluminum processing technology is not yet mature, due to long-term exposure to sunlight, aluminum surface by seawater erosion more serious situation does exist, especially the high purity aluminum material. Although it sounds a bit inconceivable now, but at the time of limited technology, it has indeed become a major problem hindering its application. of better performance of aluminum alloy which has become a dynamic force of scientific and technological factors.
Therefore, for a long period of time, steel with its high hardness, low cost in the field of shipbuilding champion. However, steel ships have a fatal weakness - weight problems. The hull weight will eventually feel the speed and payload, the greater the hull structure, the stronger the reprint capacity, the corresponding steel hull will become cumbersome and difficult to control. On the contrary, the lighter the ship, the higher the ship speed, the ship owners can bring greater economic benefits, therefore, the study of better performance of aluminum alloy which has become a dynamic force of scientific and technological factors.
At present, with the rapid development of science and technology, aluminum production costs dropped significantly, aluminum alloy performance optimization. Scientists have developed a high corrosion resistance, weldability, ductility of marine aluminum alloy, aluminum for the ship widely used to remove the obstacles. Which 5083 and 5086 are widely used in the hull structure of the keel wing, curved outer plate and the outboard plate three parts. 6061 and 6063 are mainly used for the upper structure of the ship, such as armor and so on.
