Pure aluminum plate is categorized as 1 series aluminum plate.

For instance, 1060 is a member of the 1 series.

Alloy aluminum plate can be broadly classified into 7 series, ranging from 2 to 8.

For example, 2A21 belongs to the 2 series, 3003 belongs to the 3 series, 5052 belongs to the 5 series, and so on.

1. 1000 series

The 1000 series consists of pure aluminum plates, such as 1060.

The primary component of this type of aluminum plate is aluminum, which constitutes over 99%.

2. 2000 series

The 2000 series is an aluminum plate with copper as the primary alloying element. The content of copper can vary between 2% to 5% or higher, depending on the specific application.

Compared to other brands, the 2000 series aluminum alloy plate is known for its hardness and is commonly referred to as aviation aluminum. However, due to its limited usage in civil applications, the production of 2000 series alloy aluminum plate is relatively low.

As a result, the price of 2000 series aluminum plate is relatively high. Currently, the 5052 series has replaced the 2000 series in civil applications.

3. 3000 series

The 3000 series aluminum plate is primarily composed of manganese, with a manganese content ranging from 2-5%. Representative varieties of the 3000 series include the 3003 aluminum plate and 3a21 aluminum plate.

The main reason for the popularity of 3000 series aluminum plates is their significant anti-rust performance, making them suitable for use in humid environments such as air conditioning and refrigeration. Additionally, the 3000 series aluminum plate has a distinct price advantage over other alloy plates.

4. 4000 series

The 4000 series aluminum plate is primarily composed of manganese. However, it is not yet extensively utilized at present.

5. 5000 series

The 5000 series represents a range of alloy aluminum plates, including 5052, 5083, and other grades. This series is widely used in China and around the world, making it the most commonly used aluminum alloy plate.

6. 6000 series

The 6000 series is a combination of the 4000 and 5000 series, and its main alloy elements include silicon and magnesium. The representative grade of this series is the 6061-T6 aluminum plate, which belongs to the solid heat melting treatment aluminum plate.

7. 7000 series

The 7000 series is an aluminum plate that primarily utilizes 7075 as its representative grade. Its performance is comparable to the 2000 series, primarily in terms of hardness. However, it is not frequently utilized at present.

8. 8000 series

The 8000 series is primarily represented by 8011, which serves as the main component for bottle caps. However, it is not commonly utilized at present.
