In the marine environment, marine grade aluminium need to have extremely high corrosion resistance to cope with harsh conditions such as salt spray and seawater. The thickness range of corrosion resistance marine grade aluminium is usually 1.5-30mm, the width range is usually 1000-3100mm, and the length range is usually 1000-13000mm. These specifications meet the needs of different ships and offshore structural components. Haomei marine grade aluminium plate is usually certified by authoritative classification societies such as BV, LR, ABS, CCS, KR, DNV, RINA, etc. These certifications ensure that its quality and performance meet international standards and the requirements of the marine industry. These certifications ensure that their quality and performance meet international standards and the requirements of the marine industry.

Below is a detailed description of several common corrosion resistance marine grade aluminium alloys:

5083 corrosion resistance marine grade aluminium:

- Low density: Compared to other metal materials, aluminum alloys have a lower density, which helps reduce the overall weight of the ship.

High toughness: 5083 marine grade aluminium plate has excellent toughness, able to withstand large external impact without easy fracture.

High corrosion resistance: In the marine environment, 5083 marine aluminium plate shows excellent corrosion resistance, able to resist the erosion of seawater and salt spray.

Weldability: easy to weld, easy to process and assemble in the shipbuilding process.

Application scope: mainly used for hull structure, deck, engine pedestal and other key parts, due to its high strength, corrosion resistance and good weldability, it can be well adapted to the harsh marine environment.

5086 corrosion resistance marine grade aluminium:

Good ductility: it has good ductility and can form complex shapes during processing.

Strong corrosion resistance: similar to 5083 marine grade aluminum plate, 5086 marine grade aluminum plate also shows strong corrosion resistance.

Applications: commonly used in the manufacture of boat bottoms and transom plates and other components that need to withstand greater water pressure and corrosive environments.

5052 corrosion resistance marine grade aluminium:

Good processing performance: easy to process into various shapes and sizes, suitable for complex ship structure manufacturing.

Good corrosion resistance: shows good corrosion resistance in general marine environments.

Applications: although not as commonly used as 5083 and 5086 marine grade aluminum plates, 5052 marine grade aluminum plates can still be used for non-critical structures or auxiliary parts of ships.

6061 corrosion resistance marine grade aluminium:

High bending strength: it has high bending strength and is suitable for parts that need to withstand bending stresses.

Good ductility: In addition to high bending strength, it also has good ductility.

Application scope: mainly used for ship's cantilever, bridge and other parts that need to bear bending and tensile stress.

7075 corrosion resistance marine grade aluminium:

High strength: one of the highest strength of all aluminum alloys, suitable for parts with very high strength requirements.

Good abrasion resistance: excellent abrasion resistance, able to maintain a long service life in harsh working environments.

Scope of application: mainly used in the manufacture of anchor chains and other components that need to withstand great tension and wear.

There are many types of corrosion resistance marine grade aluminium alloys, each with its own unique advantages and application scope. When choosing marine grade aluminium alloy, it is necessary to make comprehensive consideration according to the specific use of the ship, working environment and performance requirements.
