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

1. The 1000 series represents 1050 1060 1070. The 1000 series aluminum plate is also called pure aluminum plate. Among all the series, the 1000 series belongs to the series with the most aluminum content. The purity can reach more than 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 conventional industries at present. Most of the current circulation in the market are 1050 and 1060 series. The minimum aluminum content of the 1000 series aluminum plate is determined according to the last two Arabic numerals. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5% or more to qualify as a product. my country’s aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 should reach 99.5%. In the same way, the aluminum content of 1060 series aluminum plates must reach more than 99.6%.

2. The 2000 series represents 2A16 (LY16) and 2A06 (LY6) 2000 series aluminum plates are characterized by high hardness, among which copper has the highest content, about 3-5%. The 2000 series aluminum plate belongs to aviation aluminum, which is not commonly used in conventional industries at present. At present, there are fewer manufacturers producing 2000 series aluminum sheets in our country. The quality can not be compared with foreign countries. Currently imported aluminum sheets are mainly provided by South Korean and German manufacturers. With the development of my country’s aerospace industry, the production technology of 2000 series aluminum plates will be further improved.

3. The 3000 series mainly represents 3003 3003 3A21. It can also be called anti-rust aluminum plate. The production process of 3000 series aluminum plate in my country is relatively excellent. The 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0-1.5. It is a series with better anti-rust function. Routinely used in humid environments such as air conditioners, refrigerators, and undercars, the price is higher than the 1000 series, and it is a more commonly used alloy series.

4. 4000 series The aluminum plate represented by 4A01 4000 series belongs to the series with high silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance Product description: Has the characteristics of heat resistance and wear resistance

5. 5000 series stands for 5052.5005.5083.5A05 series. The 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate 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. In the same area, the weight of aluminum-magnesium alloy is lower than other series. Therefore, 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 series of hot-rolled aluminum plates, so it can be used for oxidation deep processing. In my country, the 5000 series aluminum plate belongs to one of the more mature aluminum plate series.

6. The 6000 series means that 6061 mainly contains magnesium and silicon. Therefore, the advantages of the 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product, suitable for applications that require high corrosion resistance and oxidation resistance. Good workability, excellent interface characteristics, easy coating, good processability. Can be used on low pressure weapons and aircraft connectors.

The general characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability and strong corrosion resistance.

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

7. The 7000 series means that 7075 mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy. It is a heat-treatable alloy. It belongs to superhard aluminum alloy and has good wear resistance. The thick 7075 aluminum plate is all ultrasonically detected, which can ensure no blisters and impurities. The high thermal conductivity of the 7075 aluminum plate can shorten the forming time and improve work efficiency. The main feature is that the hardness is high. 7075 is a high-hardness, high-strength aluminum alloy, which is often used in the manufacture of aircraft structures and futures. It requires high-stress structural parts and mold manufacturing with high strength and strong corrosion resistance. Currently basically rely on imports, my country’s production technology needs to be improved. (A foreign company in the company once proposed that the domestic 7075 aluminum plate was annealed unevenly, and the surface and internal hardness of the aluminum plate were inconsistent)

8. The 8000 series is more commonly used as 8011, which belongs to other series. In my memory, the aluminum plate is mainly used as a bottle cap, and it is also used in radiators, most of which are aluminum foil. Not very commonly used.

Nine 9000 series is a spare series, the technology is so developed now, in order to cope with the emergence of aluminum plates containing other alloy elements, the International Aluminum Strip Federation specifically indicated that the 9000 series is a spare series, waiting for another new variety to appear to fill the gap in the 9000 series .
