The classification of aluminum coil material

The 1000 series stands for 1050106010701000 series aluminum coils, which are also called pure aluminum coils. Among allcheap coated aluminium coil - Decoulife series, the 1000 series belongs to a series with more 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 a more commonly used series in the current conventional industry. At present, most of the 1050 and 1060 series are circulating on the market. The 1000 series aluminum plate determines the lower aluminum content of this series 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 be qualified. product. my country's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. In the same way, the aluminum content of 1060 series aluminum plates must reach 99.6% or more.

2000 series aluminum coils represent 2A16 (LY16) 2A06 (LY6) 2000 series aluminum coils. The characteristic of the 2000 series aluminum coils is that the hardness is relatively high. Among them, the original copper content is relatively high, about 3-5%. The 2000 series aluminum sheet is aerospace aluminum, which is not often used in conventional industries at present. At present, there are few factories producing 2000 series aluminum plates in our country. The quality cannot be compared with foreign countries. Currently imported aluminum coils are mainly provided by South Korean and German production companies. With the development of my country's aerospace industry, the production technology of 2000 series aluminum plates will be further improved.

3000 series aluminum coil is mainly represented by 300330033A21. It can also be called anti-rust aluminum coil. The production process of 3000 series aluminum coil in my country is comparatively. The 3000 series aluminum plate is made of manganese as the main component. The content is between 1.0-1.5. It is a series with better anti-rust function. It is commonly used in humid environments such as air conditioners, refrigerators, and undercars. The price is higher than the 1000 series. It is a more commonly used alloy series.

4000 series aluminum coil is represented by 4A014000 series aluminum plate, which belongs to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to construction materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance. Product description: It has the characteristics of heat resistance and wear resistance.

5000 series represents 5052.5005.5083.5A05 series. The 5000 series aluminum plate belongs to the more commonly used alloy aluminum coil 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 hot-rolled aluminum plate series, so it can be used for oxidation deep processing. In my country, the 5000 series aluminum sheet is one of the more mature aluminum sheet series.

6000 series represents that 6061 mainly contains two elements of magnesium and silicon, so it concentrates the advantages of 4000 series and 5000 series 6061 is a cold-treated aluminum forged product, suitable for applications with high requirements for corrosion resistance and oxidation. Good usability, excellent interface characteristics, easy coating, and good processability. It can be used on low-pressure weapons and aircraft joints.

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, ship parts and hardware, electronic parts and joints, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves and valve parts .

7000 series represents 7075 mainly containing zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy and a heat-treatable alloy. It is a super hard aluminum alloy and has good wear resistance. 7075 aluminum coil is stress-relieved and will not deform or warp after processing. All super large The ultra-thick 7075 aluminum plates are all ultrasonically detected, which can ensure no blisters and impurities. The 7075 aluminum plates have high thermal conductivity, which can shorten the forming time and improve work efficiency. The main feature is that the hardness 7075 is a high-hardness, high-strength aluminum alloy, which is often used in the manufacture of aircraft structures and futures. It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance. At present, it basically relies on imports, and my country's production technology needs to be improved. (The company once proposed that the domestic 7075 aluminum coil is not uniformly annealed, and the surface and internal hardness of the aluminum coil are inconsistent.)

The more commonly used 8000 series is 8011, which belongs to other series. In my memory, the aluminum coil used as the main function of the bottle cap is also used in the radiator, and most of the application is aluminum foil.
