Aluminum coil classification

1000 Series

It stands for 1000 series aluminum sheet, also known as pure aluminum sheet. 1000 series is one of the series with the most aluminum content among all series. The purity can reach more than 99.00%. Since it does not contain other technical elements, the production process is relatively single and the price is relatively cheap, so it is the most commonly used series in the conventional industry. Most of the aluminum sheets in the market are 1050 and 1060 series. 1000 series aluminum sheets determine the minimum aluminum content of this series according to the last two Arabic numerals, for example, the last two Arabic numerals of 1050 series are 50, according to the international grade naming principle, the aluminum content must reach 99.5% or more to be qualified products. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. By the same token, the aluminum content of 1060 series aluminum sheet must reach 99.6% or more.
2000 series aluminum sheet
Representative 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, including the highest content of copper elements, about 3-5%. 2000 series aluminum plate belongs to the aviation aluminum, not often used in the conventional industry. There are fewer manufacturers producing 2000 series aluminum plates in China. The quality cannot be compared with foreign countries. The imported aluminum plates are mainly provided by Korean and German producers. With the development of China's aerospace industry, the production technology of 2000 series aluminum plates will be further improved.
3000 series aluminum plate
Represents 3003 3003 3A21 mainly. Also can be called rust-proof aluminum plate China 3000 series aluminum plate production process is more excellent. 3000 series aluminum plate is made of manganese element as the main component. The content is between 1.0 and 1.5. It is a series with better rust-proof function. Routinely used in air conditioners, refrigerators, underneath cars and other wet environments, the price is higher than the 1000 series, which is a more commonly used alloy series.
4000 series aluminum sheet
Representing 4A01 4000 series aluminum plate belongs to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It is a material for construction, machinery parts, forging, and welding; low melting point, good corrosion resistance Product description: It has the characteristics of heat resistance and wear resistance
5000 Series
Representing 5052.5005.5083.5A05 series, 5000 series aluminum sheet belongs to the more commonly used alloy aluminum sheet series, the main element is magnesium, the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. The main characteristics are low density, high tensile strength and high elongation. In the same area, the weight of aluminum and magnesium alloy is lower than other series. Therefore, it is often used in aviation, such as aircraft fuel tanks. In the conventional industry, it is also widely used. Processing process is continuous casting and rolling, belongs to the hot-rolled aluminum sheet series, so it can do oxidation deep processing. In China, 5000 series aluminum sheet is one of the more mature aluminum sheet series.
6000 series
It mainly contains two elements of magnesium and silicon, so it concentrates the advantages of 4000 series and 5000 series. 6061 is a cold treatment aluminum forging product, suitable for applications with high requirements of corrosion resistance and oxidation. It has good serviceability, excellent interface characteristics, easy coating, and good workability. It can be used for low pressure weapons and aircraft joints.
General characteristics of 6061: excellent interface characteristics, easy to coat, high strength, good serviceability, high corrosion resistance.
Typical uses for 6061 aluminum: aircraft parts, camera parts, couplers, marine fittings and hardware, electronic fittings and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical fittings, valves and valve parts.
7000 Series
Represents 7075 Mainly contains zinc element. 7075 aluminum sheet is stress relieved and will not be deformed or warped after processing. All super large and thick 7075 aluminum sheets are ultrasonically inspected to ensure that there are no sand holes and impurities. 7075 aluminum sheets have high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is 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, corrosion resistance, high stress structural parts, mold manufacturing. Basically rely on imports, China's production process still needs to be improved. (The company once had a foreign enterprise proposed the domestic 7075 aluminum plate annealed unevenly, the problem of inconsistent surface and internal hardness of aluminum plate)
8000 series
More commonly used for 8011 belongs to other series. My memory is to do the cap as the main function of the aluminum plate, also applied in the radiator, most of the applications for aluminum foil. Not too commonly used.
9000 series
Belong to the spare series, so advanced in technology, in order to cope with the emergence of aluminum plates containing other alloy elements, the International Aluminium Sheet and Strip Federation has indicated that 9000 series is a spare series, waiting for another new species to fill the gap of 9000 series.
