Building Materials
Aluminum coil is a versatile material widely used in packaging, construction, electronics, transportation, and other industrial applications. It is available in various forms, including aluminum coils, color-coated aluminum coils, strips, sheets, and plates, to meet different processing and application requirements.
Common aluminum grades include 1100, 1060, 1050, 3003, 3004, 3104, 5005, 5052, 6061, 5754, and 5083, offering different combinations of strength, corrosion resistance, formability, and machinability for a wide range of applications.
1000 Series Aluminum Coils&Sheets
The 1000 series aluminum is also known as commercially pure aluminum, with an aluminum content of 99.00% or higher. It is one of the most widely used aluminum series due to its high purity, good corrosion resistance, excellent electrical and thermal conductivity, and relatively low cost.
Among the 1000 series, 1050 and 1060 aluminum are particularly common. 1050 aluminum contains at least 99.5% aluminum, while 1060 aluminum contains at least 99.6% aluminum, making them suitable for applications requiring high aluminum purity and good formability.

3000 Series Aluminium Coil & Sheet
3000 series, including 3004, 3004, and 3104, is known as AL-Mn alloy, which is composed of 1.0-1.5% manganese elements. AL-Mn series is often used in humid environments such as air conditioners, refrigerators, and car bottoms. Its price is higher than that of the 1000 series.
| Grade | Width | Thickness | Temper | Applications |
| 3003 | 100-2,500 mm | 0.2-2.5mm | O, H12, H14, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36, H38 | Wine bottle caps, beverage bottle caps, cosmetic caps, etc. |
| 3004 | 100-2,500 mm | 0.2-8mm | F, O, H12, H14, H16, H18, H19, H22, H24, H26, H28, H112, H114 | Lamp holders, shutter material, heat sink, LCD back panels, bottle caps, the substrate for prepainted aluminum coil, etc. |
| 3104 | 100-2,500 mm | 0.2-10mm | F, O, H12, H14, H16, H18, H19, H22, H24, H26, H28, H111, H112, H114 | Lamp holder material, shutters, can material, LCD back panels, cake tray, the substrate for color coated aluminum coil, etc. |
The strength 3003 aluminum coil is slightly higher than that of the 1000 series. Its plasticity is high in annealed and semi-cold hardening states. But after cold work hardening, its plasticity and machinability are poor, but its corrosion resistance and weldability are getting better. Compared to 3003, the 3004 aluminum coil is of higher strength. Also, it has good processing performance, weldability, and corrosion resistance. 3104 aluminum alloy has high strength and excellent elongation, as well as good corrosion resistance, formability, and weldability. It is suitable for thinning and stretching to reduce material consumption.
5000 Series Aluminium Coil & Sheet
5000 series, including 5005, 5083, 5052, etc., is the more commonly used series aluminum. The series is added 3-5% magnesium, so it is also known as aluminum-magnesium alloy. This aluminum series is processed by continuous casting and rolling technology and belongs to hot-rolled aluminum series, so it can also be further processed by oxidation. In China, the 5000 series aluminum is one of the more mature series. Its main features are low density, high tensile strength, and high elongation. The weight of the same area of the magnesium-aluminum alloy is lighter than that of other series of aluminum. Therefore, the 5000 series is often used in the aviation industry, such as aircraft fuel tanks.
Mechanical Properties
