5251 5454 5083 Aluminum Sheet

 5251 aluminum sheet was registered by the European Aluminum Association in 1972. It is a high-strength, corrosion-resistant and rust-proof aluminum. 5251 has good corrosion resistance, high strength, wear resistance and good welding performance. It is widely used for structural parts and pressure vessels in aerospace, automobiles, railways, ships, construction, metallurgy and other fields.

5251 aluminum alloy can be heat treated in various states, with high mechanical properties and hardness. The commn tempers are O, H32, H34, H36, etc., which can improve its strength and hardness. After heat treatment in H32 state, the hardness of 5251 aluminum alloy can reach 65~75HB.

5454 aluminum sheet is an Al-Mg alloy with good anti-rust effect. It has high strength, about 20% higher than 5052 aluminum plate, which can adapt to relatively harsh environments, and has excellent corrosion resistance. In addition, 5454 aluminum plate also has good plasticity and good formability, and is mostly used in welding structures, pressure vessels, ships and marine facility pipelines, and tanker barrels.

The construction of marine pipelines requires materials to cope with the harsh marine environment, so choosing the right materials is critical. In this field, 5454 aluminum plate has attracted much attention due to its excellent performance and has become the preferred material for marine pipeline construction.

5083 plate is a non-heat-treatable alloy known for its resistance to extreme environments, including seawater corrosion and industrial chemicals. Due to its ultra-high strength with limited machinability, aluminium plate 5083 is the material of choice for marine and waterborne applications, often in shipbuilding. Other uses for this alloy include transportation applications such as rail, truck and car bodies, as well as pressure vessels and food processors.

5083-H116 aluminum plate is a hot-rolled aluminum plate. The main features of 5083-H116 aluminum plate are low density, high tensile strength, high elongation, good machinability, corrosion resistance and welding performance. As cars, ships and airplanes become important modern means of transportation, the demand for 5083-H116 aluminum plate will also increase.
