How many types of metal aluminum plates are there? Where is it used?

When we buy aluminum veneers, we often see that 1100 aluminum plates are used as raw materials. So what exactly do these aluminum plate models represent?

After sorting out, it is found that the current aluminum plates can be roughly divided into 9 categories, that is, 9 series. The following is a step-by-step introduction:

1XXX series are pure aluminum, the aluminum content is not less than 99.00%

2XXX series are aluminum alloys with copper as the main alloying element

3XXX series are aluminum alloys with manganese as the main alloying element

4XXX series are aluminum alloys with silicon as the main alloying element

5XXX series are aluminum alloys with magnesium as the main alloying element

The 6XXX series are magnesium-silicon aluminum alloys with magnesium as the main alloying element and Mg2Si phase as the strengthening phase

7XXX series are aluminum alloys with zinc as the main alloying element

8XXX series are aluminum alloys with other elements as main alloying elements

9XXX series is a spare alloy group


1. Representative of 1000 series 1050 1060 1070 1100

The 1000 series aluminum plate is also called pure aluminum plate. Among all the series, the 1000 series belongs to the series with the most aluminum content, and the purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries. The 1050 and 1060 series are mostly circulated on the market. The 1000 series aluminum plate determines the minimum aluminum content of this series according to the last two Arabic numerals, such as 1050 series, according to the international brand naming principle, the aluminum content must reach 99.5% or more to be a qualified product.

2. 2000 series representative 2A16 2A06

The 2000 series aluminum plate is characterized by high hardness, with the highest content of copper, which is about 3% to 5%. 2000 series aluminum plates are aviation aluminum materials, which are not often used in conventional industries.

Three. 3000 series representative 3003 3004 3A21

3000 series aluminum plates can also be called anti-rust aluminum plates. The production technology of 3000 series aluminum plates in my country is relatively excellent. The 3000 series aluminum plate is made of manganese as the main component, and the content is between 1% and 1.5%. It is a kind of aluminum with good anti-rust function. It is usually used in humid environments such as air conditioners, refrigerators, and undercars. The price is higher than the 1000 series, and it is also a commonly used alloy series.

Four. 4000 series represents 4A01

The 4000 series is a series with higher silicon content. Usually the content of silicon is between 4.5% and 6%. It belongs to construction materials, mechanical parts, forging materials and welding materials.


Five. 5000 series representative 5052 5005 5083 5A05

The 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3% and 5%, so it is also called aluminum-magnesium alloy. In my country, the 5000 series aluminum plate is one of the more mature aluminum plate series. Its main characteristics are low density, high tensile strength, and good ductility. In the same area, the weight of aluminum-magnesium alloy is lower than other series, so it is often used in the aviation industry. Of course, it is also widely used in conventional industries.

Six. 6000 series represents 6061

The 6000 series mainly contains two elements of magnesium and silicon, so it has the advantages of the 4000 series and the 5000 series, and has good corrosion resistance and oxidation resistance. 6061 is easy to coat and easy to process, so it is often used to make various joints, magnetic heads, and valve parts.

Seven. 7000 series represents 7075

The 7000 series mainly contains zinc and is also an aerospace alloy. It is an aluminum-magnesium-zinc-copper alloy with good wear resistance. 7075 aluminum plate is stress-relieved, will not deform after processing, has very high hardness and strength, so it is often used in the manufacture of aircraft structures and futures.

8. 8000 series represents 8011

The 8000 series belong to other series and are not commonly used. The 8011 series are aluminum plates whose main function is to make bottle caps. They are also used in radiators, and most of them are used in aluminum foil.

Nine.9000 series is a spare series, used to deal with the appearance of aluminum alloy plates with other elements.
