The 5xxx aluminum alloy grades have 5052,5083, 5754, 5182, 5454,etc. It is currently the most widely used alloy series with high cost performance, excellent processability and weldability. Therefore, 5000 series aluminum alloy are a good choice for rail transportation.
5454 Al-Mg alloy is a wrought alloy with medium to high strength and excellent weldability. Its strength is approximately the same as that of 5154 and about 20% greater than that of 5052. 5454 aluminum is commonly used in welded structures such as pressure vessels and ships.
Alloy 5454 was used in tank trucks in the early 1950s, and it has good anti-corrosion properties. In addition, 5454 plates can be used in high-temperature environments, or transport high-temperature liquids. 5454 h32 aluminum is a popular choice.
5454 aluminum alloy plate production process: cold rolling processing rate of more than 70%. The annealing temperatures for states 0, H22, H24, H26, and H28 are 300°C, 260°C, 250°C, 230°C, and 200°C, respectively, and the holding time is 1 hour. The 5454 alloy H2n and O state plates produced by this process have stable properties and good formability, which meet the requirements of the EN485 standard.
5754 aluminum sheet has the characteristics of medium strength, good welding performance and excellent processing and forming performance. 5754 aluminum coil can be used to manufacture tank car bodies and bulkheads, which can reduce the weight of tank cars, increase the load, reduce fuel consumption and reduce exhaust emissions.
Moreover, the 5754 aluminum plate has strong corrosion resistance and can greatly prolong the service life of the tank car. Therefore, it is favored by the tanker truck making industry and has become the designated aluminum plate for many tank car manufacturers.
The magnesium content of 5754 aluminum sheet is higher than that of 5052, so the machinability is better. The silicon content of 5754 aluminum plate is also more than that of 5052. The silicon content affects the forging function and corrosion resistance of aluminum alloy, so 5754 aluminum plate has better forging functionality and corrosion resistance.
