The raw material used to make the tank body is 5 series alloy aluminum plate, also called aluminum-magnesium alloy plate. Magnesium is the main alloying element, and the magnesium content is 3-5%. The different magnesium content determines the performance and use of the 5 series different aluminum alloy plate. The main alloys of aluminum-magnesium plate are: 5083, 5052, 5005, 5754, 5182, 5252, 5254, 5356, 5454, 5456, 5457, 5652, 5657 and so on. The production of the tank body of the tanker has high requirements on the aluminum plate and the processing technology. For example: good corrosion resistance, processing performance, can be used for bending, stamping, stretching and other processes, strong pressure resistance, etc. These requirements are in line with the features of the 5 series aluminum-magnesium alloy plate.
Because the magnesium content of 5083 aluminum plate is higher than other 5 series aluminum alloys plates, and the hardness is also stronger, belongs to the high-hardness aluminum-magnesium alloy plate. The magnesium (Mg) content of 5083 aluminum plate can reach between 4.0% and 4.9%, usually, the middle value is 4.5% in the production process, so 5083 aluminum plate is also called Almg4.5 aluminum plate. 5083 aluminum plate sheet has low density, high tensile strength and high elongation; good formability, high strength, good corrosion resistance and weldability, suitable for oxidation deep processing. The tank body and wave shields is usually made of 5083-H111 aluminum plate; 5083-O aluminum plate sheet is softer than 5083-H111, so, the tank lid, bulkhead and the tank head of the tank cylinder is made of 5083-O aluminum plate sheet, because 5083-O aluminum sheet is relatively soft and suitable for bending. In addition, at the temperature within 135℃, the mechanical properties of 5083-O/H111 Performance is better than 5454-O/H111. Therefore, according to the “Cement Quality Management Regulations”, when the temperature of the bulk material to be transported is not higher than 135°C, such as cement, the aluminum alloy tanker/powder tanker can choose 5083 aluminum plate as the raw material.
5083 aluminum sheet plate is commonly used in tank truck (fuel tanker, air reservoir, powder tanker, tankers cylinder, LNG storage tank, tanker trailer, fuel tanker trailer, etc.), ships, vehicle materials, automobile and aircraft plate weldments. It is also used in pressure vessels, refrigeration equipment, TV towers, drilling equipment, transportation equipment, etc. that require strict fire protection.
