According to the content of alloy elements, aluminum plates can be divided into 8 series: 1, 2, 3, 4, 5, 6, 7, 8.

Application of 1-8 series aluminum alloy:

Series 1 aluminum plates: 1050, 1060, 1100. In all series, Series 1 belongs to the series with the largest aluminum content. 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 currently the most commonly used series in conventional industries. At present, most of the 1050 and 1060 series are in circulation on the market. The minimum aluminum content of the 1000 series aluminum plate is determined according to the last two Arabic numerals. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand naming principle, the qualified product must be above 99.5% aluminum content. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 aluminum plate must reach 99.5%. Similarly, the aluminum content of 1060 series aluminum plate must reach 99.6% or more.

2 series aluminum plates: 2A16 (LY16), 2A06 (LY6). 2 series aluminum plates are characterized by high hardness, among which copper element content is the highest, about 3-5%. 2 series aluminum plate belongs to aviation aluminum, which is not often used in conventional industry at present. At present, there are few manufacturers producing 2 series aluminum plates in China. The quality cannot be compared with that of foreign countries. At present, imported aluminum plates are mainly provided by Korean and German manufacturers. With the development of China's aerospace industry, the production technology of 2 series aluminum plates will be further improved.
