What Are Differences of 5059 and 5083 Aluminum in Tanker Manufacturing

5059 aluminum plate

5059 aluminum alloy is a new generation of alloy developed on the basis of 5083, and its strength performance is particularly outstanding. Its tensile strength can reach 340-380MPa, and its yield strength is around 180-220MPa, which can withstand greater pressure and impact. This feature enables 5059 aluminum alloy to better ensure transportation safety in tanker transportation scenarios that require long-distance transportation and complex road conditions.

In terms of corrosion resistance, aluminum 5059 also performs well. The relatively high zinc content in the alloy helps to improve its corrosion resistance. In addition, the aluminum-magnesium alloy itself is easy to form a dense oxide film on the surface, which can effectively resist the erosion of external corrosive media. It is an extremely reliable choice for transporting corrosive chemicals, petroleum products and other liquids.

In terms of fatigue resistance, 5059 aluminum alloy performs well. During the long-term use of tank trucks, the tank body is constantly subjected to alternating loads such as vibration and impact, which is very easy to produce fatigue cracks. The excellent fatigue resistance of 5059 aluminum alloy greatly extends the service life of tank trucks and reduces maintenance costs.

5059 aluminum alloy is widely used in the manufacture of chemical tank trucks, oil tank trucks and some special tank trucks for transporting dangerous goods due to its high strength, high corrosion resistance and fatigue resistance.

The goods transported by these tank trucks are often highly corrosive and dangerous, and the performance requirements of the tank material are extremely strict. 5059 aluminum alloy can just meet these requirements to ensure the safety and stability of the transportation process.

5083 aluminum plate

5083 aluminum alloy is a widely used rust-proof aluminum, which belongs to aluminum-magnesium alloy. It has medium strength, with a tensile strength generally between 270-310MPa and a yield strength of about 110-150MPa. It can effectively cope with various stresses during transportation while ensuring the structural strength of the tank. Under various complex transportation conditions, the tank made of 5083 aluminum alloy can maintain good structural integrity.

One of the most prominent advantages of 5083 aluminum alloy is its excellent corrosion resistance. The magnesium element in the alloy prompts it to form a strong and dense oxide film on the surface. This protective film is like a layer of protective armor for the tank, which can effectively block the erosion of corrosive media such as seawater and acid and alkali solutions. This feature makes 5083 aluminum alloy particularly suitable for transporting various corrosive liquids, such as chemical raw materials, food and beverages (some fruit juices with a certain pH value, etc.). In the transportation of food and beverages, the 5083 aluminum alloy tank will not affect the product quality due to corrosion, ensuring the safety and quality stability of the transported items.

Good welding performance is also a highlight of 5083 aluminum alloy. In the process of tank truck manufacturing, welding is a key process, which is directly related to the sealing and overall strength of the tank body. 5083 aluminum alloy can achieve high-quality welded joints through common welding methods such as argon arc welding, ensuring good sealing performance of the tank body and guaranteed overall strength. This not only improves the efficiency of the tank truck manufacturing process, but also makes the manufacturing cost relatively controllable, so it is favored by tank truck manufacturers.

In tank truck manufacturing, 5083 plate can be seen everywhere. Common oil tank trucks, some liquid tank trucks, and some chemical raw material transport tank trucks with high corrosion resistance requirements often use 5083 aluminum alloy as the tank material. For example, in the field of oil tank trucks, 5083 aluminum alloy can effectively resist the erosion of trace corrosive components that may be contained in oil products, ensuring the long-term stable operation of oil tank trucks.

5059 vs 5083

Strength and rigidity

The high strength of 5059 aluminum alloy makes it perform well in application scenarios that need to withstand greater pressure and impact. For tank trucks that transport liquefied gas with high pressure or travel in complex road conditions and bumpy environments, 5059 aluminum alloy can provide more reliable safety protection. The medium strength of 5083 aluminum alloy is sufficient for general liquid transportation scenarios, and it has good flexibility while ensuring strength, which is more beneficial for the molding of some complex tanks.

Corrosion resistance

Although both alloys have good corrosion resistance, 5059 aluminum alloy shows better corrosion resistance than 5083 aluminum alloy in certain specific strong corrosion environments due to the addition of zinc. However, in most common corrosive environments, 5083 aluminum alloy can also provide reliable corrosion resistance with its stable oxide film protection mechanism, which is sufficient to meet the needs of general tank truck transportation.

Processing performance

The processing performance of 5083 aluminum alloy is relatively better. Its good weldability and formability make it easier for manufacturers to process it into various complex tank parts. Although 5059 aluminum alloy has high strength, it requires more sophisticated process control during processing to ensure that its material properties are not affected during the forming process. When manufacturing some tanks with simple structures and extremely high strength requirements, the advantages of 5059 aluminum alloy can be fully utilized; while for tanks with complex shapes and requiring a large number of welding processes, 5083 aluminum alloy is a better choice.

In tank truck manufacturing, 5059 and 5083 aluminum alloys have their own advantages. 5059 aluminum alloy has unique value in the field of high-end and special tank truck manufacturing with its high strength, high corrosion resistance and fatigue resistance; 5083 aluminum alloy has become the preferred material widely used in the manufacturing of various conventional tank trucks with its mature and reliable performance, good processability and excellent cost performance. When selecting materials, manufacturers need to comprehensively consider multiple factors such as the tank truck's transportation medium, operating environment, cost budget, etc., weigh the performance differences between the two alloys, and make the most appropriate decision to create a safe, reliable, and high-performance tank truck product.
