Aluminium Plates For Marine Use
Aluminium plates for marine use 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 low density, high toughness, high stiffness and corrosion resistance. Ship designers feel that aluminum plates are more suitable for shipbuilding than thick steel plates. The application advantages of aluminum plates on ships are the production cost of aluminum is low, so it is more reasonable to use aluminum profiles to manufacture ships.
The application advantages of aluminium plates for marine use on ships:
1, Because the density of marine aluminium plate is low and the net weight is lighter than other raw materials, the overall net weight of the ship made of aluminum marine plate is between 15 and 20% lighter than that of the ship made of thick steel plate, so that the designer can reduce the volume of the single engine of the boat, improve the speed of sailing. The fuel consumption will be greatly reduced, and the ships made of aluminum raw materials are more reliable, the actual operation is easier, and the conveying capacity is stronger.
2, The corrosion resistance of marine aluminum plates reduces maintenance costs such as oiling, and can extend the service life (usually more than 20 years). The marine grade aluminum plate use 5000 series aluminum alloy which have good anti corrosion performance. So the service life of aluminum boat can be extended.
3, Aluminium plates for marine use have good production and processing performance, easy to carry out various types of production and processing such as laser cutting, stamping processing, cold-formed steel, forming and cutting, suitable for the streamlined hull. It can be pressed and extruded large and medium-sized wide and thick-walled aluminum profiles, Reduce the number of welds and make the hull construction rational and lightweight.
