Types and uses of Aluminum Coil

According to the different metal elements contained in aluminum coil, aluminum coil can be divided into 9 categories, that is, 9 series:

1.1000 series represents 1050 1060 1070 1000 series aluminum coil, also known as pure aluminum coil. Among all series, 1000 series belongs to the series with the largest aluminum content. The purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively single and the price is relatively cheap. It is the most commonly used series in conventional industry at present. At present, most of the products in circulation in the market are 1050 and 1060 series. The minimum aluminum content of 1000 series aluminum coil is determined according to the last two Arabic numerals. For example, the last two Arabic numerals of 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5%, and the above is regarded as qualified products. China's aluminum alloy technical standard (GB / t3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5% Similarly, the aluminum content of 1060 series aluminum coil must reach more than 99.6%.

2. 2000 series aluminum coil represents 2A16 (Ly16) 2A06 (LY6) 2000 series aluminum coil, which is characterized by high hardness, of which the original content of copper is the highest, about 3-5%. 2000 series aluminum coil belongs to aviation aluminum material, which is not often used in conventional industry at present.

3. 3000 series aluminum coil mainly represents 3003 3A21. It can also be called antirust aluminum coil. The production process of 3000 series aluminum coil in China is relatively excellent. 3000 series aluminum coil is mainly composed of manganese. The content is between 1.0-1.5. It is a series with good antirust function. It is commonly used in humid environments such as air conditioner, refrigerator and underbody. The price is higher than 1000 series. It is a more commonly used alloy series.

4.4000 series aluminum coil represents 4a014000 series aluminum coil, which belongs to the series with high silicon content. Generally, the silicon content is between 4.5-6.0%. It belongs to building materials, mechanical parts, forging materials and welding materials; Low melting point, good corrosion resistance Product Description: it has the characteristics of heat resistance and wear resistance.

5. 5000 series represents 5052.5005.5083.5ao5 series. 5000 series aluminum coil belongs to the commonly used alloy aluminum coil series. The main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum magnesium alloy. The main features are low density, high tensile strength and high elongation. Under the same area, the weight of aluminum magnesium alloy is lower than that of other series Therefore, it is often used in aviation, such as aircraft fuel tank. It is also widely used in conventional industry. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum coil series, so it can do deep oxidation processing. In China, 5000 series aluminum coil is one of the more mature aluminum coil series.  

6.6000 series represents 6061, which mainly contains magnesium and silicon, so it integrates the advantages of 4000 series and 5000 series. 6061 is a cold-treated aluminum forging product, which is suitable for applications with high corrosion resistance and oxidation requirements. Good usability, excellent interface characteristics, easy coating and good processability. It can be used in low-pressure weapons and aircraft joints.

7.7000 series represents 7075, which mainly contains zinc. It also belongs to Aviation series. It is aluminum magnesium zinc copper alloy, heat treatable alloy and superhard aluminum alloy with good wear resistance. 7075 aluminum coil is stress relieved and will not deform and warp after processing All super large and super thick 7075 aluminum coil are detected by ultrasonic, which can ensure that there are no sand holes and impurities. 7075 aluminum coil has high thermal conductivity, which can shorten the forming time and improve the work efficiency. The main feature is high hardness. 7075 is a high hardness and high strength aluminum alloy, which is commonly used in the manufacture of aircraft structures.

8.8011 is commonly used in 8000 Series, which belongs to other series

9.9000 series is a spare series, and science and technology are now so developed. In order to cope with the emergence of aluminum coils containing other alloy elements, the International Federation of aluminum coils and strips specially indicates that 9000 series is a spare series, waiting for another new variety to fill the gap of 9000 series.
