5754 5454 Aluminum Sheet for Trailer
The aluminum plate widely used in the field of transportation has the advantages of high strength, good extrudability, good weldability, and good corrosion resistance. It is especially suitable for use as aluminum car bodies, underframes, and frames. While ensuring the strength of the car body, the weight of the car body is reduced, energy is effectively saved, and operation and maintenance costs are reduced.
5xxx aluminum-magnesium alloys represented by 5052, 5083, 5754, 5454 are the most widely used alloy series, with high cost performance, excellent processability and weldability. 5 series aluminum alloy is a good choice for rail transit like semi-trailer.
In the 5754 alloy, magnesium is the main strengthening element, which plays a certain role in solid solution strengthening. The solid solubility of magnesium in aluminum is 17.4% at 450°C and 1.9% at 100°C. Manganese and chromium play a supplementary strengthening role, which can increase the recrystallization temperature, titanium can refine the casting structure, and iron and silicon are impurities, which should be controlled. EN AW 5754 h11 is a popular temper.
5754 aluminum plate belongs to the aluminum alloy that cannot be strengthened by heat treatment, and is mainly determined by the solid solution strengthening and fine grain strengthening of Mg atoms. During the production of 5754 aluminum alloy plate, the ingot is annealed after hot rolling and cold rolling, and the annealing process is the key to the final performance of the finished plate.
5052 and 5754 aluminum plate belong to luminum-magnesium alloy, and it is difficult to distinguish them from the appearance. But the 5754 aluminum sheet price is relatively high, 200-300 dollars higher than that of 5052 aluminum sheet price.
The magnesium alloy content of 5052 aluminum plate is lower than that of 5754 aluminum plate, so there is a certain difference in hardness between the two. Usually, the Webster hardness of 5052 aluminum plate is around 8-12 degrees, and the hardness of 5754 aluminum plate is around 12-14 degrees.
5454 aluminum sheet is also a Al-Mg alloy, a typical antirust aluminum, with medium strength, good formability, corrosion resistance and weldability, and meets the requirements of marine pipelines for fatigue strength, plasticity and corrosion resistance of materials.
The marine pipeline made of 5454 aluminum coil has a long service life and high material performance, which can reduce the number of maintenance during use. At the same time, it is also a common material for pressure vessels such as fuel tanks and oil tanker.
The magnesium content of 5454 aluminum plate is 2.4-3.0%, and it also contains a small amount of silicon, copper, zinc, manganese and other elements. The tensile strength is greater than 215MPa, which is about 20% higher than the strength of 5052 aluminum plate, and its characteristics are roughly the same as 5154, but the corrosion resistance in harsh environment is better than 5154 aluminum plate. 5454 h34 aluminum sheet can be used in high temperature environment, or transport high temperature liquid.
