Material classification and use of aluminum plates
Board material division and use
According to the content of alloying elements, aluminum plates can be divided into 8 series, namely 1***, 2***, 3***, 4***.5***.6***.7***.8 ***
1-8 series aluminum alloy use introduction: 1××× series aluminum sheet
1××× series aluminum sheet: representative 1050, 1060, 1100. In all series, the 1××× series belongs to a series containing more aluminum. The purity can reach above 99.00%. Because it does not contain other metal elements, the production process is relatively simple and the price is relatively cheap. It is a series commonly used in the conventional industry. Most of the current circulation on the market is the 1050 and 1060 series. The 1000 series aluminum plate determines the low aluminum content of this series according to the two Arabic numerals after Zui. For example, the two Arabic numerals are 50 after the 1050 series zui. According to the international brand nomenclature, the aluminum content must reach 99.5%. product. China's aluminum alloy technical standards (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. The same reason, the aluminum content of the 1060 series aluminum plate must reach 99.6% or more.
2××× series aluminum sheet
2××× series aluminum sheets: represent 2A16 (LY16) and 2A06 (LY6). The 2××× series aluminum plates are characterized by high hardness, among which the copper content is high, about 3-5%. The 2××× series aluminum plates are aerospace aluminum materials and are currently not commonly used in conventional industries. At present, there are fewer manufacturers producing 2××× series aluminum plates in China. Quality is still not comparable to foreign countries. Currently imported aluminum sheets are mainly supplied by Korean and German manufacturers. With the development of China's aerospace industry, the 2××× series of aluminum sheet production technology will be further improved.
3××× series aluminum sheet
3××× series aluminum sheet: mainly 3003, 3004, 3A21. It can also be called a rust-proof aluminum plate. China's 3××× series aluminum sheet production process is superior. The 3××× series aluminum plate is composed of manganese as the main component and 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, and car bottoms, the price is higher than the 1××× series, which is a more common alloy series.
