5059 Marine Aluminum Plate

5059 marine aluminum plate belongs to the 5000 series alloy products, corrosion resistance and tensile strength are relatively good. Aluminum plate in the shipbuilding industry has been used for a long time, its low density, high strength, high rigidity and corrosion resistance and other characteristics of the shipbuilding industry is very suitable for the requirements of the selection of materials, and the use of aluminum manufacturing ship more economical. 5059 aluminum alloy plate has good corrosion resistance to seawater and good mechanical properties, so it is widely used in the field of shipbuilding and marine engineering.

5059 marine aluminum plate

The common specifications of 5059 marine aluminum plate for ships are tempers of H111, H116 and H321, thickness of 6/8/10/12/16/18mm, width of 1500/1600mm/2000mm, and different length specifications. Aluminum plate manufacturers have different quotations for different thickness specifications. Marine grade aluminum 5059 alloy is suitable for the manufacture of ship shells, cabin wall panels, decks, marine piping and other components. In addition, it can also be used to manufacture offshore platforms, offshore oil drilling platforms and other marine engineering structural parts.

The advantages of 5059 marine grade aluminum plate are mainly reflected in the following aspects:

High toughness:

This kind of aluminum plate has good toughness, which can meet the needs of ships in the use of complex sea conditions.

Corrosion resistance:

As the marine aluminum plate needs to be used in the marine environment for a long time, its corrosion resistance is very important. 5059 marine aluminium plate can long resist the corrosion of the atmosphere, steam, water and other media in the marine climate, durable.


Good weldability makes 5059 aluminum plate easier to process and connect during shipbuilding.

5059 marine aluminum plate is mainly composed of aluminum, magnesium and silicon, among which magnesium is the main strengthening element, which can improve the strength and hardness of the material. In addition, marine 5059 aluminum plate also contains a certain amount of copper and zinc and other elements, these elements can further enhance the corrosion resistance of the material. Marine grade 5059 aluminum plate has high strength, high hardness, good abrasion resistance and corrosion resistance, etc. It is easy to process and can be cut, bent, drilled, etc. 5059 aluminum alloy processing technology:

1. Milling: use milling machine and cutting tool to remove the excess part of 5059 aluminum alloy material to realize the processing of plane, surface and hole.

2. Drilling: using drilling machines and drills to make holes in 5059 aluminum alloy, holes of various diameters and depths can be achieved.

3. Welding: 5059 aluminum alloys can be joined by a variety of welding methods, including inert gas shielded welding (TIG), metal inert gas shielded welding (MIG), and resistance welding.

4. Deep-drawn die pressing: the use of a die to form 5059 aluminum alloy material under force into a desired shape in a single pass, suitable for the manufacture of metal parts and containers.

5. Forging: Plastic deformation of 5059 aluminum alloy by heating it to a certain temperature and then applying pressure to change its shape, size and properties.

6. Extrusion: By placing 5059 aluminum alloy into an extruder and applying high pressure to pass it through the extrusion machine so as to form it into the desired cross-sectional shape.

7. Stretching and bending: by applying force to stretch and bend 5059 aluminum alloy to form the desired shape and curve.

The certificates of 5059 marine aluminum plate, which need to be determined by different manufacturers and regions. Large and powerful marine aluminum plate manufacturers may obtain relevant quality certificates such as CSS, DNV, BV, LR, ABS, KR, RINA to prove the quality and environmental performance of the marine grade aluminum plate products.
