In the process of aluminum sheet processing, various alloying elements are added to achieve some special mechanical properties of the <><>aluminum sheet.
The 8 series are 1-8 series respectively. For example, 2A21 belongs to 2 series, 3003 belongs to 3 series, 5052 belongs to 5 series and so on.
The 1000 series are pure aluminum plates, such as _1060. The main component of this type of aluminum plate is aluminum. above 99%
The 2000 series are aluminum sheets with copper as the main alloying element. The copper content can reach 2%-5%, or higher, depending on the specific application. 2000 series hardness relative to other grades
Much higher, because the 2000 series aluminum alloy plates commonly used in aerospace are also called aviation aluminum. Due to the fact that it is not widely used in civilian use, there are currently fewer factories producing 2000 series alloy aluminum sheets. Similarly, the price of aluminum plates of the 2000 series is relatively high. At present, the 2000 series is basically replaced by the 5052 series for civilian use.
The 3000 series is an alloy aluminum plate with manganese as the main alloying element. The content of manganese is between 2-5%. The representative varieties of the 3000 series include 3003 aluminum plate and 3a21 aluminum plate. The main thing is that the 3000 series aluminum plate has a certain anti-rust performance and is widely used in humid environments such as air conditioners and refrigerators. Compared with other alloy plates, the price has a great advantage,
The 4000 series is an aluminum alloy plate with silicon as an alloying element, which is not widely used at present.
The 5000 series is a representative series of alloy aluminum plates. There are mainly 5052 5083 and other grades. It is the most commonly used aluminum alloy plate in my country and internationally. Let's take the 5052 series as an example to talk about the 5000 series aluminum plate. The advantage is that the specific gravity is light, the specific gravity of the 5052 aluminum plate is 2.68, and the weight of the 5052 aluminum plate under the same area is lower than that of other grades of aluminum plate. 2. High tensile strength. The tensile strength of 5052 is higher in the same specification of aluminum plate, and it has better anti-deformation ability. 3. Good elongation, the elongation rate of 5052 aluminum plate is 15-30%, which can ensure the good effect of stamping, bending and bending. 4 The main alloying element is magnesium, which has the excellent properties of magnesium, and has good anti-corrosion and anti-rust effects, which is incomparable to the 3003 series. The 5052 series also has good anodizing properties, which can further improve the chemical advantages. Therefore, 5052 series aluminum plates are often used in aircraft fuel tanks, precision electronic components, hardware building materials, security doors, etc. that require high strength and good corrosion resistance.
The 6000 series is a combination of 4000 and 5000. The main alloying elements include silicon and magnesium, and the representative grade is 6061-T6 aluminum plate. It belongs to solid hot melt treated aluminum plate.
The 7000 series is the aluminum plate with 7075 as the main representative brand. Mainly reflected in the hardness, the performance is very close to the 2000 series. Currently not commonly used. Basically replace the 5000 series
The 8000 series is mainly represented by 8011. In my memory, the aluminum plate with the main function of making bottle caps is not commonly used.
Alloy aluminum sheet can also be divided into cold rolling and hot rolling. The main difference is anodization, and hot rolled aluminum sheet can be anodized.
