Both the 5754 aluminum sheet and the 5083 aluminum sheet belong to the aluminum-magnesium alloy aluminum sheet. The main difference between the two is the magnesium alloy content, hardness and elongation. The magnesium alloy content of the 5754 aluminum sheet is around 3%, and the magnesium alloy content of the 5083 aluminum sheet is as high as around 4.5%. At the same time, the hardness of 5083 aluminum sheet is higher than that of 5754 aluminum sheet, of course, the price is also higher than that of 5083 aluminum sheet. Generally, the higher the magnesium alloy content, the higher the hardness, so customers can choose 5754 aluminum sheet or 5083 aluminum sheet according to actual needs.
The 5754 aluminum sheet belongs to the Almg3 series, and the magnesium alloy content is higher than that of the 5052 aluminum sheet, which is higher than that of the 5052 aluminum sheet. 5754 aluminum sheet is a medium-strength aluminum alloy sheet, the magnesium alloy content is between 2.6 and 3.6, it has good anti-rust and corrosion resistance, no color difference on the anodized surface, excellent processability, excellent corrosion resistance, high fatigue strength, high weldability It is widely used in welding structures, storage tanks, pressure vessels, ship structures and offshore facilities, automobile manufacturing, transportation tanks, etc. Due to the advantages of hardness and tensile strength, it has been used in high-speed rail noise barriers. In recent years, it has been widely used in high-speed rail noise barrier panels.
5083 to O state aluminum sheet, O state is softer, and the can lid needs to be bent, and the partition part is also 5083 to O state. In addition, some manufacturers also use 5754H111 aluminum sheets to produce tanks. The aluminum sheets suitable for tank car bodies are mainly 5 series and 6 series related products. The 5 series is an aluminum alloy with magnesium as the main alloying element, the 6 series is an aluminum alloy with magnesium and silicon as the main alloying element and the Mg 2 Si phase as the strengthening phase, and the main alloy grades include: 5052 aluminum sheet, 5083 aluminum sheet, 5754 aluminum sheet, 6061 aluminum sheet and 6082 aluminum sheet.
5052 aluminum sheet is AL to Mg series alloy aluminum sheet, which is the most widely used anti-rust aluminum, with high strength and corrosion resistance. But it cannot be strengthened by heat treatment. It has good plasticity when it is semi-cold work hardened, and has low plasticity when it is cold work hardened. It can be polished. The magnesium alloy in the 5083 aluminum sheet has high strength, and the heat-treated alloy has good machinability, corrosion resistance and welding performance. It is widely used in transportation vehicles, such as ships, aircraft, vehicles and pressure vessels (liquid tank trucks, refrigerated trucks, refrigerated containers), etc.
The 5754 aluminum sheet has the characteristics of medium strength, good corrosion resistance, weldability and easy processing and forming. It is a typical alloy in the Al to Mg series alloy. The 5754 aluminum alloy sheet in different heat treatment states is an Seals), the main material used in the canning industry.
