5754 aluminum plate and 5083 aluminum plate belong to aluminum magnesium alloy aluminum plate. The difference between them is mainly due to the different content of magnesium alloy, hardness and elongation. The magnesium alloy content of 5754 aluminum plate is around 3%, and that of 5083 aluminum plate is around 4.5%. The hardness of 5083 aluminum plate is higher than that of 5754 aluminum plate. Of course, the price of 5083 aluminum plate is also higher. Generally, the higher the magnesium alloy content, the higher the hardness. Therefore, customers can choose 5754 aluminum plate or 5083 aluminum plate according to their actual needs.
5754 aluminum plate belongs to Al-Mg series. The content of magnesium alloy is higher than that of 5052 aluminum plate. 5754 aluminum plate is a medium strength aluminum alloy plate with magnesium alloy content of 2.6-3.6, which has good rust and corrosion resistance. The anodized surface has no color difference, excellent processability, excellent corrosion resistance, high fatigue strength, high weldability and medium static strength. 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 barrier plate in recent days.
5083-O state aluminum plate is softer in o state, while the tank cover needs to be bent, and the clapboard is also in 5083-O state. In addition, some manufacturers use 5754h111 aluminum plate to produce tank bodies.
Aluminum plates applicable to tank car body are mainly 5 series and 6 series related products. Series 5 is an aluminum alloy with magnesium as the main alloy element, and series 6 is an aluminum alloy with magnesium and silicon as the main alloy elements and Mg 2Si phase as the strengthening phase. The main alloy grades include 5052 aluminum plate, 5083 aluminum plate, 5754 aluminum plate, 6061 aluminum plate and 6082 aluminum plate.
The magnesium alloy in 5083 aluminum plate has high strength. The alloy after heat treatment 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.
5754 aluminum sheet has the characteristics of medium strength, good corrosion resistance, weldability and easy processing and forming. It is a typical Al Mg alloy. In foreign countries, 5754 aluminum alloy plates with different heat treatment conditions are the main materials used in automobile manufacturing (car doors, molds, seals) and can making industry.
