In shipbuilding, aluminum alloys are commonly used due to their excellent strength-to-weight ratio, corrosion resistance, and weldability. The choice of the specific aluminum alloy plate depends on various factors, such as the type and size of the ship, operational conditions, and design requirements. However, two commonly used aluminum alloy plates for shipbuilding are 5083 and 6061:

Aluminum Alloy 5083: This alloy is widely used in shipbuilding due to its high strength, excellent corrosion resistance, and good weldability. It has good formability and is suitable for various shipbuilding applications, including hull structures, superstructures, and deck components. Aluminum alloy 5083 offers good resistance to seawater and industrial chemicals, making it suitable for marine environments.

Aluminum Alloy 6061: While not as commonly used as 5083, aluminum alloy 6061 is also suitable for certain shipbuilding applications. It offers good strength and excellent corrosion resistance. Aluminum alloy 6061 is often used in smaller boats, pleasure crafts, and recreational vessels. It is less resistant to corrosion in seawater compared to 5083, but its lighter weight and high strength make it suitable for specific ship designs where weight savings are crucial.

Aluminum plates used on ships generally need to have superior corrosion resistance. The 5-series aluminum plate has the strongest anti-rust and anti-corrosion ability among aluminum alloys, so it is often used on ships.
