What Are Corrosion Resistant Alloys for Marine Materials
One of the most important properties of aluminum is its corrosion resistance, which allows structures to have a fairly long service life even when the structures are exposed to extreme weather changes, seawater and freshwater environments or various soils and chemicals.
Combined with its strong mechanical properties, this natural corrosion resistance has led to aluminum being used in almost all areas, from shipbuilding, pipelines, wires, various chemical tanks and pipes, to the beverage and food industry and high-performance aerospace applications.
Aluminum alloys are basically divided into seven categories, of which only 5000 and 6000 series marine aluminum alloys are internationally recognized and can be used on ships. Other aluminum materials, such as 2000 and 3000 series aluminum alloys, are strictly prohibited from being used on ships that must come into contact with seawater due to their insufficient salt resistance and weather resistance.
Marine material 3.3547 en aw 5083 is an aluminum alloy plate specially used for shipbuilding. It is widely used for its good corrosion resistance, welding performance and mechanical properties. 5083 aluminum plate belongs to Al-Mg alloy. Its main alloying element is magnesium, and usually contains a small amount of other elements such as silicon (Si).
Features of 5083 aluminum plate
Corrosion resistance: 5083 aluminum plate has good corrosion resistance, especially suitable for marine environment.
Weldability: 5083 aluminum plate has excellent weldability and is suitable for a variety of welding methods.
Machinability: It has good cold working performance, which is easy to process into various shapes.
Strength: It has medium strength, but its strength can be further improved by work hardening.
Formability: It has good formability, which is easy to bend and stretch.
Fatigue resistance: It has good fatigue resistance, suitable for long-term dynamic loads.
Applications
Shipbuilding: 5083 aluminum plates are widely used in the construction of ship hulls, decks, bulkheads and other parts.
Offshore platforms: Structural parts for offshore platforms.
Naval equipment: Structural parts for military ships.
Marine transportation: LNG carriers and other marine transportation tools.
Other applications: 5083 aluminum plates are also suitable for the manufacture of pressure vessels, tank trucks, refrigerated containers, tank trucks and other occasions that require corrosion resistance.
Supply status
H temper: The common tempers are H111, H112, H116, H321, etc.
O temper: the fully annealed state.
