APPLICATION OF 1-8 SERIES ALUMINUM ALLOYS

Jinminghui2021-10-18

According to the content of alloying elements, aluminum sheets can be divided into 8 series: 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000.

1 x x x series aluminium alloy sheets: representing 1050, 1060, 1100 alloy. Among all the series, the 1000 series belongs to the series with the highest aluminium content. The purity can reach over 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 industries. At present, the majority of circulation in the market is 1050 and 1060 aluminum alloy series. The lowest aluminium content of 1000 series aluminium sheets is determined by the last two Arabic numbers. For example, the last two Arabic numbers of 1050 alloy series are 50. According to the naming principle of international brands, the aluminium content must be above 99.5% before qualified products are obtained. Our countrys aluminium alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminium content of 1050 can reach 99.5%. Similarly, the aluminium content of 1060 series aluminium plates must reach 99.6%.

2 x x x series aluminium alloy sheet

2 x x x series aluminium alloy sheets: representing 2A16 (LY16), 2A06 (LY6). The hardness of 2000 series aluminium sheets is higher, and the original content of copper is the highest, about 3-5%. 2000 series aluminium sheet belongs to aviation aluminium material, which is not widely used in conventional industry at present. At present, there are few factories producing 2 x x series aluminium sheets in China. The quality can not be compared with foreign countries. At present, imported aluminium sheets are mainly supplied by Korean and German manufacturers. With the development of Chinas aerospace industry, the production technology of 2000 series aluminium sheet will be further improved.


3000 series aluminium alloy sheets

3 x x x series of aluminium sheets: representing 3003, 3004, 3A21 alloy mainly. It can also be called anti-rust aluminium plate. The production process of 3000 series aluminium sheet in China is excellent. The main component of 3 series aluminium sheets is manganese, with content ranging from 1.0% to 1.5%. It is a series with better rust-proof function. Conventional applications in air conditioning, refrigerators, car bottoms and other humid environment, the price is higher than 1 series, is a more commonly used alloy series.


4 x x x series aluminium alloy sheets

4 x x x series aluminium alloy sheet: representative 4A01. The aluminium sheet of 4 series belongs to the series with high silicon content. Usually the silicon content is between 4.5 and 6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance product description: with heat resistance, wear resistance characteristics.


5 x x x series aluminium alloy sheet

5 x x x series aluminium alloy sheets: representing 5052, 5005, 5083, 5A05 series. 5 x x x series aluminium plate belongs to the more commonly used alloy aluminium plate series, the main element is magnesium, the content of magnesium is between 3-5%. It can also be called Al-Mg alloy. The main characteristics are low density, high tensile strength and high elongation. In the same area, the weight of Al-Mg alloy is lower than that of other series, so it is often used in aviation, such as aircraft fuel tank. It is also widely used in conventional industries. Processing technology is continuous casting and rolling, which belongs to hot-rolled aluminium plate series, so it can be oxidized deep processing. In our country, the 5 x x series aluminium sheet belongs to one of the more mature aluminium sheet series.


6 x x x series aluminium alloy sheets

6 x x x series alloy aluminium sheet: representing 6061. It mainly contains magnesium and silicon, so it concentrates the advantages of 4 x x x series and 5 x x x series. 6061 is a cold-treated aluminium forging product, which is suitable for applications requiring high corrosion resistance and oxidation resistance. It has good usability, excellent interface characteristics, easy coating and good workability. It can be used in low-pressure weapons and aircraft joints.


7 x x x series aluminium alloy sheets

7 x x x series aluminium sheet: representing 7075 aluminum alloy. It mainly contains zinc. It also belongs to aviation series, is Al-Mg-Zn-Cu alloy, heat-treated alloy, belongs to superhard aluminium alloy, has good wear resistance. 7075 aluminium sheet is stress-relieved and will not deform or warp after processing. All super-large and super-thick 7075 aluminium sheets are detected by ultrasonic wave, which can ensure that there are no sand holes and impurities. 7075 aluminium sheet has high thermal conductivity and can be shortened. Forming time, improve work efficiency. The main feature is that the hardness of 7075 is high hardness, high strength aluminum alloy, which is often used in the manufacture of aircraft.


8 x x x series aluminium alloy sheets

8 x x x series aluminium alloy sheet: the commonly used 8011 aluminium sheet belongs to other series. Aluminum plate is mainly used as bottle cap. It is also used in radiator. Aluminum foil is mostly used. In business is not very common series.
