The Application of Aluminum Sheet in Transportation

1. The Application of Aluminum Sheet in Transportation Abstract: The transportation is an expanding market for the aluminum sheet. The applications are mainly in shipbuilding, auto making, tanker truck manufacturing and aerospace. For these applications, the aluminum sheet should have the related certification like DNV,ABS,LR,etc. Marine Grade Metals and Alloy for Jon Boat A jon boat is a special class of aluminum fishing boat with a flat or nearly flat bottom. The chosen marine grade metals are aluminum alloy. The aluminum sheet or jon boat floor chooses marine grade aluminum tread plate like 5052, 5083 or 6061. 6061 aluminum tread plate is a kind of checkered aluminum plate with high hardness. In the T6 state, the hardness is around 95HB. When choosing this patterned aluminum plate, you must pay attention to whether there is any bending in the processing process for its being performance is not good.

2. 5xxx aluminum checker plates are processed with 5-series aluminum plate such as 5052 aluminum plate or 5083 aluminum plate as raw material, which has good corrosion resistance, hardness and anti-rust performance. They are usually used in special places, such as ships, carriages and other humid environments. 5083 aluminum tread plate is a representative product of non-slip aluminum plate. It has a high hardness and high tensile strength. The hardness has obvious advantages in similar products. 5083 aluminium plate also has better corrosion resistance than 5052 or 6061 aluminum. The common tempers of 5052 aluminum diamond plate are T6 and T651. Under normal circumstances, the internal stress of T6 will be relatively large, and the processing will deform. Therefore, the most suitable state for processing is T651. The T651 state is stretched on the basis of T6 to eliminate internal stress. The strength of 5052-T651 aluminum plate cannot be compared with that of 2 series and 7 series alloy products. However, due to the presence of magnesium and silicon elements, 5052 aluminum plate has excellent weldability, corrosion resistance and cold workability.

3. 5 bar pattern aluminum tread plate is often used for the boat floor. Since the willow-shaped patterns on the surface of the aluminum plate are arranged in parallel according to five concave-convex patterns and each pattern has an angle of 60-80 degrees with other patterns, this pattern has excellent anti-skid performance. Auto Aluminium 3003 and 5086 The water-cooled plate is an important component of the thermal management system of new energy vehicles, and it is usually used in load-bearing and corrosion-resistant environments. Therefore, when selecting the manufacturing material of the water-cooled plate, the strength and corrosion resistance of the material need to be considered. Automobile water-cooled panels generally use aluminum brazing composite materials, and the process is mainly raw material stamping-cleaning-flux coating-riveting-brazing-testing-gluing and other processes. In order to ensure the stamping and stretching requirements of the water-cooled plate, the materials used are required to have good stretching ability. The 3003 h14 aluminum sheet has excellent performance and is currently the most widely used choice for automobile water-cooled plate. The fenders are usually installed behind the four tires of the car, the front two are fixed

4. on the left and right lower sills, and the rear two are fixed on the rear bumper. There are mainly aluminum alloy fender, cowhide fender, plastic fender, rubber fender. The aluminum alloy car fender is mainly made of 3003 aluminium alloy. 3003 aluminum belongs to the AL-Mn alloy. It is an anti-rust aluminum widely used. Its strength is higher than that of industrial pure aluminum. It has good corrosion resistance, good weldability, and poor machinability. The condenser, evaporator, oil cooler and radiator in the automobile air-conditioning equipment and heat exchangers are 100% made of aluminum. 3003 aluminum plate is also used for this application. The use of aluminum for the car body can reduce the weight of the whole car to a certain extent, realizing the lightweight of the car body, thereby reducing carbon dioxide emissions, improving fuel efficiency, and ensuring energy saving effect to a greater extent. There are 5182, 5083, 5086,etc are used in the truck compartment. The strength, toughness, and fatigue strength of forged aluminum alloy wheels are significantly better than those of cast aluminum alloy wheels, and they also have the advantages of good corrosion resistance, precise dimensions, small processing volume, and strong performance reproducibility. It mainly uses Al-Mg alloy and Al-Si-Mg alloy. 5xxx aluminum alloy is the most commonly used deformed aluminum alloy in wheel forging, mainly including: 5052-O, 5154-O, 5454-O, 5083-O, 5086 aluminum plate. 5xxx forged aluminum alloy wheels have high corrosion resistance and are suitable for manufacturing wheels working in extreme environments. 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.

5. 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,

6. 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 sheet can be used in high temperature environment, or transport high temperature liquid.
