Representative of 1000 series aluminum plate is also known as pure aluminum plate. Among all series, 1000 series belongs to the series with the most aluminum content. The purity can be over 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap, which is the most commonly used series in the current conventional industry. Most of the 1050 and 1060 series are in circulation on the market. The minimum aluminum content of 1000 series aluminum plate is determined according to the last two Arabic numbers. For example, the last two Arabic numbers of 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5% and above is qualified product. In China's aluminum alloy technical standard (GB / t3880-2006), the aluminum content of 1050 is 99.5%. In the same way, the aluminum content of 1060 series aluminum plates must be more than 99.6%. Aluminum coil is widely used in electronics, packaging, construction, machinery and other aspects. There are many aluminum coil manufacturers in China, and the production process has caught up with developed countries.

According to the different metal elements contained in the aluminum coil, the aluminum coil can be divided into 9 categories, that is, 9 series. The following is a step-by-step introduction:

Aluminum coil classification

1000 series

2000 series aluminum plate

The representative 2A16 (Ly16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, of which the original copper content is the highest, about 3-5%. 2000 series aluminum plate belongs to aviation aluminum material, which is not often used in conventional industry. There are few manufacturers of 2000 series aluminum plates in China. The quality cannot be compared with that of foreign countries. The imported aluminum plates are mainly provided by Korean and German manufacturers. With the development of China's aerospace industry, the production technology of 2000 series aluminum plate will be further improved.

3000 series aluminum plate

It mainly represents 3003, 3003, 3A21. It can also be called antirust aluminum plate. The production process of 3000 series aluminum plate in China is excellent. 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0-1.5. It is a series with better antirust function. Conventional application in air conditioning, refrigerator, underbody and other humid environment, the price is higher than 1000 series, is a more commonly used alloy series.

4000 series aluminum plate

The aluminum plate represented by 4a014000 series 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. It has low melting point and good corrosion resistance. Product Description: it has the characteristics of heat resistance and wear resistance.

5000 Series

For 5052.5005.5083.5a05 series. 5000 series aluminum plate belongs to the commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum magnesium alloy. It is characterized by low density, high tensile strength and high elongation. In the same area, the weight of aluminum magnesium alloy is lower than other series, so 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, belonging to the hot rolling aluminum plate series, so it can do deep oxidation processing. In China, 5000 series aluminum plate belongs to one of the more mature aluminum plate series.

6000 Series

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

General features of 6061: excellent interface features, easy coating, high strength, good usability, strong corrosion resistance.

Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, ship accessories and hardware, electronic accessories and joints, decorative or various hardware, hinge head, magnetic head, brake piston, hydraulic piston, electrical accessories, valves and valve parts.

7000 series

Represents that 7075 mainly contains zinc. It also belongs to the aviation series. It is an aluminum magnesium zinc copper alloy. It is a heat-treatment alloy. It belongs to super hard aluminum alloy. It has good wear resistance. 7075 aluminum plate is stress relieved and will not deform or warp after processing. All super thick 7075 aluminum plates are detected by ultrasonic, which can ensure no sand holes and impurities. 7075 aluminum plate has high thermal conductivity, can shorten forming time and improve working efficiency. The main feature is that the hardness of 7075 is a high hardness and high strength aluminum alloy, which is commonly used to manufacture aircraft structures and futures. It requires the manufacture of high stress structural parts and dies with high strength and corrosion resistance. Basically relying on imports, China's production process still needs to be improved. (a foreign company of the company once proposed that the annealing of 7075 aluminum plate made in China was uneven, and the surface and internal hardness of the aluminum plate were inconsistent.)

8000 Series

8011, which is more commonly used, belongs to other series. In my memory, the aluminum plate with the main function of making the bottle cap is also used in the radiator, most of which are aluminum foil. Not very often.

9000 series

It belongs to the standby series, so developed in science and technology. In order to cope with the emergence of aluminum plates containing other alloy elements, the international aluminum plate and strip Federation specially indicates that 9000 series is the standby series, waiting for another new variety to appear to fill the gap of 9000 series.
