For more detailed information including pricing, customization and shipping.
6061 aluminum plate is a 6000 series aluminum-magnesium-silicon alloy, and is also a type of marine aluminum plate. 6061 aluminum plate has the characteristics of good corrosion resistance, high toughness, no deformation after processing, good oxidation effect, etc., and can still maintain good operability after annealing. 6061 aluminum plate is a commonly used structural alloy. It is used in shipbuilding in the form of plates, patterned plates or profiles. Common alloy states are O, T4, T6, T651.
The corrosion resistance and welding performance of 6061 aluminum plate are not as good as 5083 aluminum plate and 5086 aluminum plate. Therefore, 6061 aluminum plate is usually not selected as the main material in large commercial ships or marine applications that require high corrosion resistance. The application of 6061 aluminum plate in shipbuilding is mainly limited to some minor or internal parts, rather than key hull structures or parts that are directly in contact with seawater.

◆ Good processing performance: 6061 aluminum plate has good machinability and forming performance, and is easy to process into parts of various shapes without deformation after processing.
◆ Medium strength: 6061 aluminum plate belongs to medium strength aluminum alloy, which can meet the strength requirements of some ship parts.
◆ Heat treatment and strengthening: 6061 aluminum plate can be improved by heat treatment, which provides flexibility for adjusting its performance.
◆ Excellent strength-to-weight ratio: 6061 aluminum plate is lighter than steel, which can reduce the weight of the ship while maintaining a certain strength.
◆ Good oxidation effect: The anodizing effect is excellent and can adapt to the marine environment.
Internal structural parts of ships: such as internal supports, frames and other parts that are not in direct contact with seawater.Deck equipment: 6061 aluminum patterned plates can be used for ship gangways and masts.Decorative parts: 6061 aluminum plates have good oxidation coloring effects, and can be used for some decorative plates or parts inside ships after anodizing.Small leisure boats: small leisure boats that do not require high corrosion resistance, such as inland cruise ships.Mechanical parts: some mechanical parts on ships that are not in direct contact with seawater.
