What Is Aluminum Coil?

Aluminum coil is a metal product for flying shearing after calendering and drawing Angle processing by casting and rolling machine.

Aluminum coil is widely used in electronics, packaging, construction, machinery, etc. Our country's aluminum coil production enterprises. The production process has caught up with the developed countries.

According to the metal elements that aluminum coil contains, aluminum coil can be divided into 9 major categories, namely 9 series.

The 1000 series:

Represents 1000 series aluminum coil is also known as pure aluminum coil, in all series, 1000 series belongs to a series with the largest amount of aluminum. 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 industry at present. Most of the 1050 and 1060 series are in circulation. The minimum aluminum content of 1000 series aluminum coil is determined according to the last two Arabic digits. For example, the last two Arabic digits of 1050 series are 50. According to the international naming principle, the aluminum content must reach 99.5% or more to be qualified products. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. In the same way, 1060 series aluminum coil must contain more than 99.6% aluminum.

2000 series aluminum coil

On behalf of 2A16 (LY16) 2A06 (LY6) 2000 series aluminum coil is characterized by high hardness, with the highest content of copper, about 3-5%. 2000 series aluminum coil belongs to aviation aluminum material, which is not often used in conventional industry. There are few manufacturers of 2000 series aluminum coils in China. The quality cannot be compared with that of foreign countries. The imported aluminum sheet is mainly supplied by Korean and German manufacturers. With the development of China's aerospace industry, 2000 series aluminum coil production technology will be further improved.

3000 series aluminum coil

Represents 3003, 3003, 3A21. It can also be called rust-proof aluminum coil in China 3000 series aluminum production process is excellent. 3000 series aluminum coil is made of manganese as the main component. The content is between 1.0 and 1.5. It is a series with better rust prevention function. Commonly used in air conditioning, refrigerator, car bottom and other humid environment, the price is higher than 1000 series, is a relatively common alloy series.

4000 series aluminum coil

The aluminum coil representing 4A01 4000 series belongs to the series with higher silicon content. The silicon content is usually between 4.5 and 6.0%. Belongs to construction materials, mechanical parts, forging materials, welding materials; Low melting point, good corrosion resistance Product Description: Heat resistance, wear resistance

The 5000 series

Represents 5052.5005.5083.5A05 series. 5000 series aluminum coil belongs to the more commonly used alloy aluminum coil series, the main element is magnesium, magnesium content between 3-5%. Can also be called aluminum magnesium alloy. The main characteristics are low density, high tensile strength, high elongation. Under the same area, the weight of Al-Mg alloy is lower than that of other series. It is often used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industry. The processing technology is continuous casting and rolling, which belongs to the hot rolled aluminum coil series, so it can do deep oxidation processing. 5000 series aluminum coil belongs to one of the more mature aluminum coil series in China.

The 6000 series

Representative 6061 mainly contains magnesium and silicon two elements, so the advantages of 4000 series and 5000 series are concentrated 6061 is a cold treatment aluminum forging product, suitable for corrosion resistance, oxidation requirements of high applications. Good usability, excellent interface features, easy coating, good processing. It can be used in low pressure weapons and aircraft joints.

General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good usability, strong corrosion resistance.

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

The 7000 series

Represents 7075 contains mainly zinc. Also belongs to the aviation series, is aluminum magnesium zinc copper alloy, is a heat treatable alloy, belongs to the super hard aluminum alloy, has good wear resistance.7075 aluminum coil is eliminated stress, processing will not deformation, warping. All ultra-large and ultra-thick 7075 aluminum coils are detected by ultrasonic, which can ensure no trachomes and impurities. The high thermal conductivity of 7075 aluminum coil can shorten the molding time and improve the work efficiency. 7075 is a high hardness, high strength aluminum alloy, often used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance of high stress structural parts, mold manufacturing. Basically depend on import, our production craft still need to be improved. (The company once had a foreign company put forward the domestic 7075 aluminum coil annealing is not uniform, the surface and internal hardness of the aluminum coil is not consistent)

The 8000 series

The more commonly used 8011 belongs to other series. In my memory, the main function of aluminum coil is to make bottle caps. It is also used in radiators, and most of the applications are aluminum foil. Not very often.

The 9000 series

Belongs to the standby series, the technology is so developed, in order to deal with the aluminum coil containing other alloy elements, the international aluminum coil federation special show 9000 series for the standby series, waiting for a new variety to fill the gap of 9000 series.

Aluminum coil has 1, low density, light weight. 2, easy to handle, can be strengthened. 3, plasticity, easy processing. 4, corrosion resistance. 5, no low temperature brittleness. 6. Good electrical and thermal conductivity. 7, sound absorption. 8. Nuclear radiation resistance. 9, beautiful, the surface can be reprocessed and other advantages.

Characteristics of aluminum coil:

1. No compound high temperature indentation on the surface. No residual stress, no deformation after shearing.

2. Painted wood grain, stone grain, realistic physical texture, fresh natural beauty. The design is free and do, give customers a wide range of personality choice, can enrich the humanistic connotation of products, give people more beautiful feeling.

3. The paint pattern made of coating and baking at high temperature has high gloss maintenance, good color stability and minimal color difference change. Polyester paint is guaranteed for 10 years and fluorocarbon paint is guaranteed for more than 20 years.

4. Select high quality aluminum, plastic and adhesive, and adopt advanced composite process. The product has the flexural and flexural strength required by the decorative coil. Under the climate condition of four seasons, the change of wind pressure, temperature, humidity and other factors will not cause bending, deformation, expansion and so on.

5. Saline-alkali acid rain corrosion resistance, its own corrosion will not live toxigenic bacteria, does not release any toxic gas, does not cause keel and fixed parts rust, flame retardant. Not less than B1 level according to national regulations.
