Why are the raw materials of contemporary ships increasingly selected from the alloy aluminum plates of aluminum plate manufacturers? Since ancient times, everyone has just started to try to build ships in order to explore the rivers and lakes. In the beginning, a person was riding on a garden tree, floating down the river, and carrying a thick tree to paddle. Everyone hollowed out the middle of the garden to allow people to sit in. This is the prototype of the ship—the wooden boat.
Along with the development trend, everyone tied two pieces of wood together with ropes and produced a raft. The advantages of the raft compared to the boat are simplicity, stability, and a large total loading area. The development trend of wooden boats is slowly, and the wooden boats are basically upgraded to yachts. The advantage of yachts is that they leave behind the application of pure pulp paper. Until modern times, the key raw materials for ships are wood.
With the progress of the scientific and technological revolution, everyone has a certain awareness of environmental protection, and cement ships have emerged to replace wooden boats, which have the characteristics of corrosion resistance and usability. In addition, the construction cost of the cement ship is cheap, the raw materials are easily available, the construction machinery and equipment and construction technology are simple, the maintenance cost is low, and it can save wood and steel. The key defect is that the dead weight is extremely large and the impact resistance is poor. It can only be used in a certain range. The emergence of steel has replaced concrete, and until now, most of the raw materials of ships are all steel. The advantage of steel is that it has sufficient compressive strength and ductility, excellent process performance and sea corrosion resistance, and the impact resistance is further improved.
In recent years, with the shortage of electric energy and the increasing awareness of environmental protection, the light weight of ships and the reuse of aluminum alloy metal composite materials are key development trends. Therefore, the alloy aluminum plate has a further development trend in specific applications.
Aluminum Company is a large and medium-sized aluminum plate manufacturer. The density of pure aluminum is 2.71kg/m3, which is only one third of the density of steel. AL-mg, the alloy has a lower density. Therefore, alloy aluminum plates and steels with the same net weight and the same thickness are relatively free of two-thirds of the square. Therefore, the quality of the alloy aluminum plates of most manufacturers will be lighter and more reasonable.
The aluminum alloy plate can be purchased and reused after application. Its energy consumption during acquisition is low, which is only 5% of that of primary aluminum production and manufacturing, and its utilization rate during smelting is high. Each cycle system consumes 203.5%-208.5%, which can be continuously multifaceted. Purchase and utilization prevent the consumption of resources and environmental pollution to the natural environment. Considering everyone's regulations on the remanufacturing of aluminum alloy metal composite materials, it is highly energy-saving. Nowadays, alloy aluminum plates have been used in large, medium and small passenger ships, cruise ships, motorboats, high-speed missile boats, patrol boats, destroyers (such as the development of some ships) and other ships.
