First-class structure
The so-called first-class structure refers to the force-bearing structure with strength as the main factor, such as the hull, large ship deckhouse, ship bridge, missile launching tube, electromagnetic gun track, etc. The electromagnetic gun has been installed on the world's largest aircraft carrier "Ford" launched by the United States in October 2013. Its launch track is made of aluminum alloy, and the test gun is also made of aluminum alloy.
Second structure
This type of structure refers to non-stressed components or components with less force, such as various perches, fuel tanks, water tanks, storage cabinets, aluminum watertight doors, windows, and covers (general rectangular windows for ships, string windows for ships, small Speedboat aluminum windows, aluminum sunroofs, aluminum shutters, various hatch covers, rectangular window windows, movable aluminum doors, marine weathertight single aluminum doors, cabin hollow doors, various ladders and springboards, passenger and driver seats, and sofas Etc.), sanitary facilities, ducts, ventilation, windshields, brackets, streamlined enclosures and handles, etc. They are mostly made of 6063, 6082, 3003 and other alloy materials.
Three types of structure
This type of structure mainly uses functional materials, which are used to make interior decorations and heat and sound insulation materials in the warehouse. Aluminum and aluminum alloys have good anodic oxidation and coloring properties, and after this treatment, they have a bright appearance and strong corrosion resistance. In addition to the non-strengthened aluminum alloy materials with various heat treatments, aluminum-plastic (aluminum-polyethylene, Al-PE) composite panels and foam aluminum materials have also been used in many applications. The foam aluminum panels are good sound insulation for submarine engine rooms. material. The core layer of the composite board is a plastic layer, and both sides or one side are thin 1100 or 3003 alloys and aluminum alloys with a thickness of 0.1 to 0.3 mm. The surface of the aluminum plate can be processed with anti-corrosion treatment, embossing, painting, printing, etc. It is characterized by light weight, proper rigidity, and better vibration and sound insulation effect. The Japan Maritime Association and the shipbuilding departments of other countries have approved it to be used as interior decorative panels for ships and ships, and can also be used as materials such as doors and windows. Materials such as glass fiber reinforced plastic and wood used in the past can be changed to these materials.
Aluminum alloy has been widely used in ships.
