Aluminum coil

1000 series
The 1000 series aluminum sheet, also known as pure aluminum sheet, boasts the highest aluminum content of all series, with purity exceeding 99.00%. Because it contains no alloying elements, its production process is relatively simple and its cost is comparatively low, making it one of the most widely used series in traditional industries today. The two most commonly available grades on the market are 1050 and 1060. The minimum aluminum content of the 1000 series is indicated by the last two digits of the grade designation; for example, the last two digits of the 1050 series are “50.” In accordance with international naming conventions, qualified products must meet an aluminum content of at least 99.5%. China’s national standard for aluminum alloys (GB/T 3880-2006) explicitly stipulates that the 1050 grade must have an aluminum content of no less than 99.5%, while the 1060 grade must contain at least 99.6% aluminum.
2000 series aluminum sheet
The 2000-series aluminum sheets, such as 2A16 (LY16) and 2A06 (LY6), are characterized by their relatively high hardness and the highest copper content, typically around 3% to 5%. These alloys are primarily used in aerospace applications and see limited use in conventional industrial sectors. In China, only a handful of companies produce 2000-series aluminum sheets, and their product quality still lags behind that of international counterparts. At present, imported 2000-series aluminum sheets are mainly supplied by manufacturers in South Korea and Germany. As China’s aerospace industry continues to grow, the production processes for 2000-series aluminum sheets are expected to undergo further improvements.
3000 series aluminum sheet
It is designated as 3003, 3003, and 3A21. It is also known as rust‑proof aluminum sheet. Our 3000 series aluminum sheets are manufactured with meticulous craftsmanship. This series uses manganese as its primary alloying element, with a content ranging from 1.0% to 1.5%, offering excellent corrosion resistance and commonly employed in components for humid environments such as air conditioners, refrigerators, and automobiles. Its price is higher than that of the 1000 series, making it one of the more widely used aluminum alloy series.
4000 series aluminum sheet
4A01 4000-series aluminum sheet belongs to the high-silicon alloy series, with a silicon content typically ranging from 4.5% to 6.0%. This series is widely used in construction materials, mechanical components, forging alloys, and welding consumables, and is characterized by a low melting point and excellent corrosion resistance. Product description: It offers both heat resistance and wear resistance.
5000 series
It is suitable for series such as 5052, 5005, 5083, and 5A05. The 5000 series aluminum sheets belong to a widely used family of aluminum alloy plates, with magnesium as the primary alloying element, typically ranging from 3% to 5%; hence, they are also referred to as aluminum–magnesium alloys. This series is characterized by low density, high tensile strength, and excellent elongation; under the same surface area, aluminum–magnesium alloys are lighter than other series. They are commonly employed in aerospace applications, such as aircraft fuel tanks, and are also extensively utilized in traditional industries. Their manufacturing process involves continuous casting and rolling, classifying them as hot‑rolled aluminum sheets, which allows for further deep‑processing treatments like anodizing. In China, the 5000 series aluminum sheets are among the most mature and well‑established aluminum sheet grades.
6000 series
6061 alloy primarily contains magnesium and silicon, thereby combining the advantages of both the 4000 and 5000 series. It is a cold‑worked aluminum forging material, well suited for applications demanding high corrosion resistance and oxidation resistance. It exhibits excellent machinability, superior interfacial properties, and is easy to coat, making it ideal for components such as low‑pressure weapons and aircraft joints.
General characteristics of 6061: excellent interfacial properties, easy to coat, high strength, good machinability, and strong corrosion resistance.
Typical applications of 6061 aluminum alloy include aerospace components, camera parts, couplings, marine piping and hardware, electronic components and connectors, decorative and other types of hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical fittings, and valves and valve components.
7000 series
7075 aluminum alloy, with zinc as its primary alloying element, belongs to the aerospace series and is a heat‑treatable Al–Mg–Zn–Cu alloy renowned for its excellent wear resistance. After stress‑relief treatment, 7075 aluminum sheets exhibit no deformation or warping following machining. All extra‑thick‑gauge 7075 aluminum plates undergo ultrasonic flaw detection to ensure they are free of porosity and inclusions. With outstanding thermal conductivity, 7075 aluminum can significantly shorten forming cycles and enhance production efficiency. This alloy boasts high hardness and superior strength, making it widely used in the manufacture of aircraft structural components and various load‑bearing parts—particularly in critical structural applications and mold‑making where high strength and corrosion resistance are essential. At present, 7075 aluminum is predominantly imported, and domestic manufacturing processes still require further improvement. (Some foreign‑invested enterprises have reported that domestically produced 7075 aluminum plates suffer from uneven annealing, resulting in inconsistent surface and internal hardness.)
8000 series
The more commonly used 8011 alloy belongs to other series. As far as I know, aluminum sheet is primarily used for manufacturing bottle caps and also for radiators; however, the latter are mostly made from aluminum foil, and their application is not particularly widespread.
9000 series
It belongs to the auxiliary series; therefore, in terms of technological development, in response to the emergence of aluminum sheets containing other alloying elements, the International Aluminum Association has stated that the 9000 series is classified as an auxiliary series and awaits the introduction of new grades to fill the existing gaps within this series.
