Aluminum coil classification

According to the different metal elements contained in the aluminum coil, the aluminum coil can be divided into 9 categories, that is, it can be divided into 9 series.
Aluminum coil classification

1000 series

2000 series aluminum coil

Representative 2A16 (LY16) 2A06 (LY6) 2000 series aluminum coil is characterized by high hardness, of which the copper content is the highest, about 3-5%. The 2000 series aluminum coils are aerospace aluminum and are not commonly used in conventional industries.

3000 series aluminum coil

Representing 3003 3003 3A21. It can also be called rust-proof aluminum coil, and China’s 3000 series aluminum coil production process is relatively excellent. The 3000 series aluminum coil is made up of manganese as the main component. The content is between 1.0 and 1.5. It is a series with better anti-rust function. Conventional applications in the humid environment of air conditioners, refrigerators, car bottoms, etc., the price is higher than 1000 series, is a more common alloy series.

4000 series aluminum coil

The aluminum coil, represented by the 4A01, 4000 series, is a series with a high silicon content. Usually the silicon content is between 4.5 and 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 the 5052.5005.5083.5A05 series. The 5000 series aluminum coil belongs to the more commonly used alloy aluminum series. The main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. Therefore, it is commonly 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 and can be used for oxidation deep processing. In China, the 5000 series aluminum coil is one of the more mature aluminum coil series.

6000 series

The representative 6061 contains mainly magnesium and silicon. Therefore, the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating and good processability. Can be used on low pressure weapons and aircraft joints.
General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability and strong corrosion resistance.
Typical uses for 6061 aluminum: aircraft parts, camera parts, couplers, marine parts and hardware, electronic parts and fittings, decorative or various hardware, hinged heads, magnetic heads, brake pistons, hydraulic pistons, electrical parts, valves and valve parts .

7000 series

The representative 7075 mainly contains zinc. Also belonging to the aviation series, it is aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress-relieved and will not be deformed or warped after processing. All super-super The thick 7075 aluminum plate is ultrasonically detected to ensure no blisters and impurities. The 7075 aluminum coil has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that the hardness of 7075 is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures.

8000 series

The more commonly used 8011 belongs to other series. Aluminum is used as the main function of the cap, and it is also applied to the radiator. Most of the applications are aluminum foil. Not very common. 7000 series

9000 series

It belongs to the spare series, and the technology is so developed. In order to cope with the appearance of aluminum plates containing other alloying elements, the International Aluminum Sheet Federation expresses that the 9000 series is a spare series, waiting for another new variety to appear to fill the gap of the 9000 series.
