Tank Car Aluminum Plate Used Some Aluminum Alloy
Aug 09, 2018

The length of aluminum alloy plates commonly used in the market is generally less than 12.5 meters, the width is less than 2.2 meters, and the thickness is generally 5/6/7/8mm. A complete tank car body generally needs 4-6 pieces of aluminum plates welded. The tank body is made of 5083H111 aluminum plate, and the can lids on both sides are made of 5083-O temper aluminum plate. The O temper is softer, and the can lid needs to be bent. Besides, the partition part is also uses the 5083-O aluminum plate. In addition, some manufacturers use 5454 H111 aluminum plate to produce cans.

The aluminum plates for tank car bodies are mainly 5000 series and 6000 series aluminum plate. The 5000 series is an aluminum alloy with magnesium as the main alloying element, and the 6 series is an aluminum alloy with magnesium and silicon as the main alloying elements. The main alloy grades include: 5052 aluminum plate, 5083 aluminum plate, 5754 aluminum plate. , 6061 aluminum plate and 6082 aluminum plate.

The 5052 aluminum plate is an AL-Mg alloy aluminum plate, which is the most widely used rust-proof aluminum with high strength and corrosion resistance. However, it cannot be heat-treated and strengthened. The plasticity is good in semi-cold hardening, and the plasticity is low during cold hardening and can be polished.

The magnesium alloy in the 5083 aluminum plate has high strength and heat-treated alloy, which has good workability, corrosion resistance and welding performance. It is widely used in transportation vehicles such as ships, airplanes, vehicles and pressure vessels (liquid tank trucks, refrigerated trucks, refrigerated containers).

The 5754 aluminum plate is characterized by moderate strength, good corrosion resistance, weldability and ease of forming. It is a typical alloy in Al-Mg alloys. In foreign countries, 5754 aluminum alloy sheets of different heat treatment conditions are the main materials used in the automobile manufacturing industry (car doors, molds, seals) and canning industry.

6061 aluminum plate has medium strength, good corrosion resistance, weldability, good processability, and can be anodized and colored. Because it contains a small amount of Cu, the strength is higher than 6063, and the quenching sensitivity is also higher than 6063. After quenching, wind quenching cannot be achieved, and re-solution treatment and quenching aging are required.

The 6082 aluminum sheet is a heat-resistant and reinforced aluminum alloy sheet with medium strength, good weldability and corrosion resistance, and is mainly used in the transportation and structural engineering industries.
