A：1. 1000 series Representative 1050 1060 1070 1000 series alloy aluminum plate is also called pure aluminum plate. In all series, 1000 series belongs to the series with the most aluminum content. The purity can reach above 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 the conventional industry. Most of the current circulation on the market is the 1050 and 1060 series. The 1000 series aluminum plates are based on the last two Arabic numerals to determine the minimum aluminum content of the series. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand nomenclature, the aluminum content must reach 99.5% to be qualified products. China's aluminum alloy sheet technical standard (GB/T3880-2006) also clearly stipulates that 1050 aluminum content reaches 99.5%. The same reason 1060 series aluminum sheet aluminum content must reach 99.6%.

Second, 2000 series alloy aluminum plate Representative 2A16 (LY16) 2A12 (LY12) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, which contains the highest copper content, about 3-5%. The 2000 series of aluminum sheets are aerospace aluminum and are currently not commonly used in conventional industries. There are fewer manufacturers of 2000 series aluminum sheets in China. Quality is still not comparable to foreign countries. Currently imported aluminum sheets are mainly supplied by Korean and German manufacturers. With the development of China's aerospace industry, the 2000 series of aluminum sheet production technology will be further improved.

Third, 3000 series alloy aluminum plate represents 3003 3003 3A21. It can also be called rust-proof aluminum plate. China 3000 series aluminum plate production process is relatively excellent. The 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0 and 1.5. It is a series with better anti-rust function. Conventional applications in the humid environment of air conditioners, refrigerators, and car bottoms, the price is higher than 1000 series, is a more common alloy series.

4. 4000 Series Alloy Aluminum Plate The aluminum plate represented by the 4A01 4000 series belongs to the series with high silicon content. Typically the silicon content is between 4.5 and 6.0%. It is a building material, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance. Product Description: It has heat-resistant and wear-resistant properties.

Five, 5000 series represents 5052.5005.5083.5A05 series. 5000 series alloy aluminum plate belongs to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series and can be used for oxidation deep processing. In China, 5000 series aluminum plates belong to one of the more mature aluminum plate series.

Sixth, 6000 series Representative 6061 mainly contains magnesium and silicon two elements, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product, which is suitable for applications with high corrosive and oxidizing requirements. Good usability, excellent interface characteristics, easy coating and good processability. Can be used on low pressure weapons and aircraft joints. The general characteristics of 6061T651: excellent interface characteristics, easy coating, high strength, good workability and strong corrosion resistance. Typical uses for 6061T651 aluminum: aircraft parts, camera parts, couplers, marine parts and hardware, electronic parts and fittings, decorative or various hardware, hinged heads, magnetic heads, brake pistons, hydraulic pistons, electrical parts, valves and valve parts .

Seven, 7000 series Representative 7075 mainly contains zinc. Also belonging to the aviation series, it is an aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress-relieved and will not deform or warp after processing. All super-super The thick 7075 aluminum plate is ultrasonically detected to ensure no blisters and impurities. The 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that the hardness of 7075 is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures. It requires high-strength structural parts and molds with high strength and high corrosion resistance. At present, it basically relies on imports, and China's production process needs to be improved. (Our company once had a foreign company proposed that the domestically produced 7075 aluminum plate was annealed unevenly, and the surface and internal hardness of the alloy aluminum plate were inconsistent).

Eight, 8000 series The more commonly used 8011 belongs to other series. I remember that the aluminum plate is the main function of the cap, and it is also applied to the radiator. Most of the application is aluminum foil. Not very common.
