Product introduction


Product characteristics

Aluminum coil is cast and rolled machine after calendering, pulling bending angle processing, for the metal products for flying shear.

Aluminum coil is widely used in electronics, packaging, construction, machinery and other aspects, the production process has caught up with developed countries. According to the different metal elements contained in the aluminum coil, aluminum coil can be divided into roughly 9 major categories, that is, can be divided into 9 series, the following step by step roughly introduced.

Aluminum Coil Classification:

  1. 1000 series
  2. Representing 1000 series aluminum sheet is also known as pure aluminum sheet, among all series 1000 series belongs to a series with the most aluminum content. The purity can reach more than 99.00%. Since it does not contain other technical elements, the production process is relatively single and the price is relatively cheap, so it is one of the most commonly used series in the conventional industry at present. Most of the aluminum sheets in the market are 1050 and 1060 series. 1000 series aluminum sheets determine the minimum aluminum content of this series according to the last two Arabic numerals, for example, the last two Arabic numerals of 1050 series are 50, according to the international grade 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%. By the same token, the aluminum content of 1060 series aluminum sheet must reach 99.6% or more.
  3. 2000 series aluminum sheet
  4. Representative 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, which has the highest content of copper elements, about 3-5%. 2000 series aluminum plate belongs to the aviation aluminum, not often used in the conventional industry. There are fewer manufacturers producing 2000 series aluminum plates in China. The quality cannot be compared with foreign countries. The imported aluminum plates are mainly provided by Korean and German producers. With the development of China's aerospace industry, the production technology of 2000 series aluminum plates will be further improved.
  5. 3000 series aluminum plate
  6. Represents 3003 3003 3A21 mainly. Also can be called rust-proof aluminum plate China 3000 series aluminum plate production process is more excellent. 3000 series aluminum plate is made of manganese element as the main component. The content is between 1.0 and 1.5. It is a series with better rust-proof function. Routinely used in air conditioners, refrigerators, underneath cars and other wet environments, the price is higher than the 1000 series, which is a more commonly used alloy series.
  7. 4000 series aluminum sheet
  8. Represented by 4A01 4000 series aluminum plate belongs to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It is a material for construction, machinery parts, forging, and welding; low melting point, good corrosion resistance Product description: It has the characteristics of heat resistance and wear resistance
  9. 5000 Series
  10. Representing 5052.5005.5083.5A05 series, 5000 series aluminum sheet belongs to the more commonly used alloy aluminum sheet series, the main element is magnesium, the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. The main characteristics are low density, high tensile strength and high elongation. In the same area, the weight of aluminum and magnesium alloy is lower than other series. Therefore, it is often used in aviation, such as aircraft fuel tanks. In the conventional industry, it is also widely used. Processing process is continuous casting and rolling, belongs to the hot-rolled aluminum sheet series, so it can do oxidation deep processing. In China, 5000 series aluminum sheet is one of the more mature aluminum sheet series.
  11. 6000 series
  12. It mainly contains two elements of magnesium and silicon, so it concentrates the advantages of 4000 series and 5000 series. 6061 is a cold treatment aluminum forging products, suitable for applications with high requirements of corrosion resistance and oxidation. It has good serviceability, excellent interface characteristics, easy coating, and good workability. It can be used in low pressure weapons and aircraft joints.
  13. General characteristics of 6061: excellent interface characteristics, easy to coat, high strength, good serviceability, high corrosion resistance.
  14. Typical uses for 6061 aluminum: aircraft parts, camera parts, couplers, marine fittings and hardware, electronic fittings and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical fittings, valves and valve parts.
  15. 7000 Series
  16. Represents 7075 Mainly contains zinc element. 7075 aluminum sheet is stress relieved and will not be deformed or warped after processing. All super large and thick 7075 aluminum plates are ultrasonically inspected to ensure that there are no sand holes and impurities. 7075 aluminum plates have high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is the hardness of 7075 is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance, high stress structural parts, mold manufacturing. Basically rely on imports, China's production process still needs to be improved. (The company once had a foreign enterprise proposed the domestic 7075 aluminum plate annealed unevenly, the problem of inconsistent surface and internal hardness of aluminum plate)
  17. 8000 series
  18. More commonly used for 8011 belongs to other series. My memory is to do the cap as the main function of the aluminum plate, also applied in the radiator, most of the applications for aluminum foil. Not too commonly used.
  19. 9000 series
  20. Belong to the spare series, so advanced in technology, in order to cope with the emergence of aluminum plates containing other alloy elements, the International Aluminium Sheet and Strip Federation has indicated that 9000 series is a spare series, waiting for another new species to fill the gap of 9000 series.

Machining Process:

Silicon has a corrosive effect on cemented carbide. Although the general will be more than 12% Si aluminum alloy is called high silicon aluminum alloy, the recommended use of diamond tools, but this is not absolute, the silicon content gradually increase the destructive force of the tool also gradually increase. Therefore some manufacturers in the silicon content of more than 8% when the use of diamond tools are recommended.

Silicon content in 8%-12% between the aluminum alloy is a transition interval, can use both ordinary carbide, can also use diamond tools. However, the use of carbide should be used by the PVD (physical plating) method, without aluminum elements and with a small film thickness. Because the PVD method and the small film layer thickness make the tool to maintain a sharp cutting edge become possible (otherwise to avoid the film layer at the edge of the abnormal growth of the need for sufficient passivation of the edge, cutting aluminum alloy will not be sharp enough), and the film layer material containing aluminum may make the blade film layer and the workpiece material affinity and destroy the film layer and the combination of tool substrate. Because the super-hard coating is mostly a compound of aluminum, nitrogen and titanium, it may cause a small amount of spalling of the carbide substrate with the film layer flaking off to cause chipping.

It is recommended to use one of the following three types of tools.

  1. 1. Ultra-fine grain carbide tools without coating
  2. 2. Carbide tools with uncoated aluminum (PVD) method, such as TiN, TiC plating, etc.
  3. 3.With diamond tools

The chip tolerance space of the tool should be large, generally it is recommended to use 2 teeth with large front and back angles (such as 12°-14°, including the back angle of the end teeth).

If only general milling surface, you can use 45 ° main offset angle of the indexable face milling cutter, with special processing aluminum alloy inserts, should be better.

Aluminum oxide was used in the laboratory in 1808 to become aluminum by electrolysis, and was used as a construction material on the spire of the Washington Monument in the United States in 1884 until now; aluminum alloy material synthesized by adding various metal elements has been widely used in various aspects of the construction industry. Aluminum alloy commonly used plate thickness: senior metal roofing (and curtain wall) system is generally 0.8-1.2mm (while the traditional one is generally ≥2.5mm).
