Aluminum plates have been used in the shipping industry for a long time, but most of them are used in ships in modern times. Aluminum plates have the characteristics of low density, high toughness, high stiffness and corrosion resistance. It is precisely for this reason that ship designers feel that aluminum plates are better than thick steel plates. Suitable for use in the shipbuilding industry, the application advantages of aluminum plates on ships, the production cost of aluminum is low, so it is more reasonable to use aluminum profiles to manufacture ships.
What are the advantages of aluminum plate?
1. Because the density of aluminum plate is low, the net weight is lighter than other raw materials. The overall net weight of ships made of aluminum plate is 15%-20% lighter than ships made of thick steel plate. In the oil consumption will be greatly reduced, aluminum raw materials used to manufacture ships have higher trust, simpler practical operation, stronger throughput.
2. The corrosion resistance of aluminum plate reduces maintenance costs such as oiling, and can extend the service life (usually more than 20 years).
3. The aluminum plate has good production and processing performance, which is convenient for laser cutting, stamping, cold-formed steel, forming and cutting and other types of production and processing, reduce the number of welds and make the hull structure rational and lightweight.
4. The electric welding performance of aluminum plate is good, and it can be very easy to carry out electric welding. The elastic mold is small, the working ability to digest and absorb the impact internal stress is large, and it has a large reliability coefficient. No ultra-low temperature ductility, most suitable for ultra-low temperature machinery and equipment.
5. Aluminum waste is very easy to acquire and can be used in a recycling system; all-aluminum boats can prevent mines from attacking and are suitable for minesweepers.
From the perspective of ship designers, the application advantages of aluminum sheets on ships can achieve better efficiency and longer service life by using aluminum alloy profiles. The development trend is rapid.
