According to different processing technologies, they can also be divided into cold rolling and hot rolling.
according to different thickness, it can be divided into thin plate and medium plate. According to GB/T388-26 standard, the thickness below .2 mm is called aluminum foil.

I.1 series represents 15 16 17 1 series aluminum plate, which is also called pure aluminum plate. Among all series, 1 series belongs to the series with the most aluminum content. The purity can reach above 99.%. 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 industry at present. At present, most of the products in the market are 15 and 16 series. The minimum aluminum content of 1 series aluminum plates is determined according to the last two Arabic numerals. For example, the last two Arabic numerals of 15 series are 5. According to the naming principle of international brands, the aluminum content must reach 99.5% or more to be qualified products. China's aluminum alloy technical standard (gB/T388-26) also clearly stipulates that the aluminum content of 15 should reach 99.5%. Similarly, the aluminum content of 16 series aluminum plates must reach above 99.6%.
2A16(LY16) 2A6(LY6)2 series aluminum plates are characterized by high hardness, among which the content of copper is the highest, about 3-5%. 2 series aluminum plate belongs to aviation aluminum material, which is not often used in conventional industry at present. At present, there are few manufacturers producing 2 series aluminum plates in China. The quality can't be compared with that of foreign countries. At present, imported aluminum plates are mainly provided by Korean and German manufacturers. With the development of China's aerospace industry, the production technology of 2 series aluminum plates will be further improved.
three 3 series aluminum plates represent 33 33 3A21. It can also be called rust-proof aluminum plate. The production process of 3 series aluminum plates in China is excellent. 3 series aluminum plates are mainly composed of manganese. The content is between 1. and 1.5. It is a series with good antirust function. Commonly used in air conditioners, refrigerators, car bottoms and other humid environments, the price is higher than 1 series, and it is a more commonly used alloy series.
aluminum plates with 4A1 4 series as the representative belong to the series with high silicon content. Generally, the silicon content is between 4.5 and 6.%. Belonging to building materials, mechanical parts, forging materials and welding materials; Product description: low melting point and good corrosion resistance: it has the characteristics of heat resistance and wear resistance
series 5 represents series 552.55.583.5A5 5 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%. It can also be called Al-Mg alloy. Its main features are 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 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, so it can be oxidized for deep processing. In China, 5 series aluminum plates belong to one of the more mature aluminum plates.
661, the representative of Liu6 series, mainly contains magnesium and silicon, so it integrates the advantages of 4 series and 5 series. 661 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. Can be used in low-voltage weapons and aircraft joints.
general characteristics of 661: excellent interface characteristics, easy coating, high strength, good usability and strong corrosion resistance.
typical uses of 661 aluminum are: aircraft parts, camera parts, couplers, ship accessories and hardware, electronic accessories and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves and valve parts.
775, the representative of 7 series, mainly contains zinc. It also belongs to aviation series. It is an Al-Mg-Zn-Cu alloy, which is a heat-treatable alloy and belongs to superhard aluminum alloy. It has good wear resistance. The 775 aluminum plate is stress-relieved and will not deform or warp after processing. All the super-large and super-thick 775 aluminum plates are detected by ultrasonic wave, which can ensure no sand holes and impurities. The 775 aluminum plate has high thermal conductivity, which can shorten the forming time and improve the working efficiency. The main feature is that 775 is an aluminum alloy with high hardness and strength, which is often used to manufacture aircraft structures and futures. It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance. At present, we basically rely on imports, and our production technology needs to be improved. (A foreign company in our company once suggested that the annealing of domestic 775 aluminum plate was uneven, which resulted in the inconsistency between the surface hardness and the internal hardness of aluminum plate)
811, which is commonly used in the 8 series, belongs to other series. As far as I can remember, it is an aluminum plate whose main function is to make bottle caps, and it is also used in radiators, most of which are aluminum foils. Not very common.
9 series belongs to the standby series, and the technology is so developed now. In order to cope with the appearance of aluminum plates containing other alloying elements, the International Federation of Aluminum Strip and Plate has specially indicated that 9 series is the standby series, waiting for another new variety to appear to fill the gap of 9 series. I'm also looking forward to it.
