Marine Grade Aluminum Plate|Why are aluminum plates widely used on ships

Aluminum plates have been used in the shipbuilding industry for a long time, but they have been widely used in ships in modern times. With the low density, high strength, high rigidity and corrosion resistance of aluminum plates, ship designers believe that aluminum plates are more suitable for shipbuilding than steel plates. The processing cost of aluminum is lower, so it is more economical to use aluminum to make ships.
There are several reasons why aluminum plates are used in shipbuilding:
1. Due to the low density of aluminum plates, the weight is lighter than other materials. The overall weight of ships made of aluminum plates is between 15 and 20% lighter than ships made of steel plates. In this way, designers can reduce the single engine capacity and increase Sailing speed; fuel consumption will be greatly reduced in convenience. Ships made of aluminum are more stable, easier to operate, and stronger in transportation.
2. The anti-corrosion performance of aluminum plate reduces maintenance costs such as oiling, and can extend the service life (usually more than 20 years).
3. Good processing and forming performance, easy to perform various forms of processing such as cutting, stamping, cold bending, forming and cutting, suitable for streamlining the hull; it can extrude large, wide and thin-walled profiles, reducing the number of welds and the use of The hull structure is rationalized and lightweight.
4. The welding performance is good, and the welding can be carried out relatively easily. The modulus of elasticity is small, the ability to absorb impact stress is large, and it has greater safety. No low temperature brittleness, it is most suitable for low temperature equipment.
5. Aluminum scrap is easy to recycle and can be recycled. Because it is non-magnetic, the compass is not affected; the all-aluminum boat can avoid mine attack and is suitable for minesweeper.
From the perspective of ship designers, ships made of aluminum alloys can achieve higher speeds and longer service lives. These advantages of aluminum alloys make it rapidly develop in ship applications. The shipbuilding industry is aluminum. Provides a broad application market.
