Металлы, используемые в судостроении

В последние годы, облегчение корпусов кораблей быстро развивалось, а судостроительная промышленность продолжала развиваться, поэтому сырье для судостроения стало важнее. Среди них, алюминиевые сплавы широко используются, и алюминиевые листы стали особенно важны. Many people don’t understand, can’t ships use steel? Сейчас многие отрасли используют сталь. That’s because of the low density, высокая прочность, high rigidity and corrosion resistance of aluminum sheets, so ship designers believe that aluminum sheets are more suitable for shipbuilding than steel sheets. The processing cost of aluminum is low, so it is more economical to use aluminum to manufacture ships.

Can aluminum sheet 6061 be used for shipbuilding?

Among the many aluminum alloys, many types of aluminum sheets can be used on ships, такой как 6061 алюминиевые листы, 7075 алюминиевые листы, 5083 алюминиевые листы, так далее. Сегодня, we will talk about 6061 алюминиевые листы. 6061 aluminum sheets are very good for ship accessories because of several characteristics. 6061 aluminum sheet is low-density and lighter than other materials, so the overall weight of ships made of 6061 aluminum sheet is 15%-20% lighter than that of ships made of steel sheet. This will greatly reduce fuel consumption and speed.

Marine aluminum sheet 6061 features

6061 aluminum sheet is commonly used in shipbuilding, especially the construction of small and medium-sized ships. It is a versatile, high-strength, corrosion-resistant alloy that is well suited for marine environments.

Сильная коррозионная стойкость

6061 алюминий имеет отличную коррозионную стойкость, especially seawater corrosion resistance, which is essential for marine applications. This corrosion resistance is due to the presence of magnesium and silicon in the alloy, which form a protective oxide layer on the surface to protect the underlying metal from salt water and other harsh marine conditions.

6061 Aluminum has a high strength-to-weight ratio

6061 aluminum has a high strength-to-weight ratio, which is critical in shipbuilding. The alloy is strong enough to meet the structural requirements of a ship’s hull while remaining lightweight, which improves fuel efficiency and speed. The lightweight nature of aluminum reduces the overall weight of a ship compared to steel, making it more efficient and reducing operating costs.

Алюминиевый лист 6061 хорошая свариваемость

6061 aluminum has excellent weldability** and can be easily fabricated and joined using traditional welding techniques such as TIG (tungsten inert gas) or MIG (metal inert gas) welding. This makes it easy to build complex ship components and join large panels of the hull, and simplifies repair work when necessary.

High machinability

6061 aluminum is highly machinable and can be easily cut, бурят, and formed into a variety of shapes and sizes, which is important when making custom parts for ships. Обрабатываемость 6061 ensures that components can be precisely manufactured, which is critical for complex parts such as bulkheads, frames, and deck structures.

Strong anodizing

6061 aluminum can be anodized to further improve corrosion resistance, which is particularly beneficial in marine environments. Anodizing also gives the aluminum an aesthetic finish, which is important for aesthetic purposes on yachts, leisure boats or naval vessels.

Impact and fatigue resistance

While aluminum is generally not as impact resistant as steel, 6061 is one of the more resilient aluminum alloys and has good fatigue resistance. This means that even under the repeated stress and vibration common in marine environments, 6061 aluminum will maintain its structural integrity for a long time.

Применение 6061 aluminum plate in shipbuilding

Hull structure: 6061 aluminum plate can be used to manufacture the main structural components of the hull, such as the hull, deck, так далее. Its light weight and high strength characteristics reduce the overall weight of the hull, which helps to improve the performance of the ship.

Accessory manufacturing: In the process of shipbuilding, 6061 aluminum plate can also be used to manufacture various accessories, such as bulkheads, лестницы, перила, так далее. These accessories not only require a certain strength and rigidity, but also require good corrosion resistance, а также 6061 aluminum plate just meets these requirements.

Maintenance and modification: For ships that have been put into use, 6061 aluminum plate is also often used for maintenance and modification. Например, when a part of the hull is damaged, 6061 aluminum plate can be used to repair it; when the ship needs to be upgraded, 6061 aluminum plate can also be used to make new parts for replacement.
