Classification of aluminium coils

According to the different metal elements contained in the aluminium coil, the aluminium coil can be divided into nine 

categories, that is, nine series:

（1）Series1000, representing the 1000 series of aluminium coils, is also known as pure aluminium coils. Among all 

series, the 1000 series belongs to the series with the largest aluminium content. The purity can reach over 99.00%. 

Because it does not contain other technical elements, the production process is relatively simple and the price is 

relatively cheap. It is the most commonly used series in conventional industries. 

（2）Series 2000 representing Series 2A16 (LY16) 2A06 (LY6) 2000 is characterized by high hardness, of which 

copper content is the highest, about 3-5%. Series 2000 aluminium coil belongs to aviation aluminium material, 

which is not often used in conventional industry. 

（3） 3000 series represents 3003 3003 3A21 mainly. It can also be called anti-rust aluminium coil. The production 

process of 3000 series aluminium coil in our country is excellent. 3000 series aluminium coils are mainly composed 

of manganese. The content ranged from 1.0 to 1.5. It is a series with better rust-proof function. Conventional applications

 in air conditioning, refrigerators, car bottoms and other humid environment, the price is higher than 1000 series, is a 

more commonly used alloy series. 

（4）The aluminium coils of series 4 and 4,000, representing the 4A01 and 4,000 series, belong to the series with

high silicon content. Usually the silicon content is between 4.5 and 6.0%. It belongs to building materials, mechanical 

parts, forging materials, welding materials, low melting point, good corrosion resistance.

（5）5000 series represents 5052.5005.5083.5A05 series. 5000 series aluminium coil belongs to the more commonly 

used alloy aluminium coil series, the main element is magnesium, the content of magnesium is between 3-5%. It can 

also be called Al-Mg alloy. 

（6）6000 series represents 6061 mainly contains magnesium and silicon. Therefore, 6061 series of 4000 and 5000 

Series is a cold-treated aluminum forging product, which is suitable for applications requiring high corrosion resistance

 and oxidation resistance. 

（7）7000 series representing 7075 mainly contains zinc. Also belongs to the aviation series, is Al-Mg-Zn-Cu alloy, is 

heat-treatable alloy, belongs to superhard aluminum alloy, has good wear resistance. 

（8）8000 Series 8011 belongs to other series. Most applications are aluminium foil. Not very often.

（9）Series 9,9000 belongs to the standby series. The International Aluminum Coil and Strip Federation indicates 

that the 9000 series is the standby series.
