Aluminum alloy has been used in the shipbuilding industry for nearly 100 years. With the rapid development of the shipbuilding industry at home and abroad, the lightweight of ships has been paid more and more attention. The high toughness, corrosion resistance and weldability of aluminum alloys are strictly required for construction. The ship offers a good choice. Due to the low processing cost of aluminum, coupled with the outstanding physical properties of aluminum alloys, aluminum manufacturing vessels are very economical. These advantages of aluminum alloys have made them develop rapidly in marine applications, and the shipbuilding industry has provided a broad application market for aluminum.


Application of aluminum alloy in ship profiles---aircraft base material:

The aircraft carrier is a giant. It is huge in size and well-built. It is a highly mobile combat platform and has an urgent need to reduce the weight of the structure. The application of aluminum alloys on aircraft carriers ranges from partial take-off and landing decks, huge lifts, numerous piping systems, to porthole covers, chandeliers, doors, compartments, cabin trim, furniture, kitchen equipment and some auxiliary machines. The application of aluminum alloy on the aircraft carrier is of great significance to reduce the weight of the aircraft carrier structure, improve stability, seaworthiness and station performance.
Advantages of application of aluminum alloy in ship profiles:
1. The aluminum alloy has a small specific gravity, which can reduce the weight of the ship, reduce the single machine capacity and increase the speed; reduce the fuel consumption and save fuel; improve the aspect ratio of the ship, increase the stability, and make the ship easy to operate; Load the weight and get extra profit.
2, aluminum alloy has good corrosion resistance, can reduce maintenance costs such as oiling, and can extend the service life (usually more than 20 years).
 3, aluminum alloy processing and forming performance is good, easy to cut, stamping, cold bending, forming and cutting and other forms of processing, suitable for streamlined hull; can squeeze large wide-width thin-walled profiles, reduce the number of welds And rationalize and lighten the hull structure.
4. The aluminum alloy has good welding performance and can be welded easily.
5. The elastic modulus of aluminum alloy is small, the ability to absorb impact stress is large, and it has greater safety.
6, aluminum scrap is easy to recycle, can be recycled.
7. Aluminum alloy has no low temperature brittleness and is suitable for low temperature equipment.
8. The aluminum alloy is non-magnetic, so the compass is not affected.
