1. According to the content of alloying elements, aluminum sheets can be divided into: 1××× series is industrial pure aluminum (Al), 2××× series is aluminum-copper alloy aluminum plate (Al--Cu), 3××× series is aluminum Manganese alloy aluminum plate (Al--Mn), 4××× series is aluminum-silicon alloy aluminum plate (Al--Si), 5××× series is aluminum-magnesium alloy aluminum plate (Al--Mg), 6××× series is Aluminum-magnesium-silicon alloy aluminum plate (AL--Mg--Si), 7××× series is aluminum-zinc alloy aluminum plate [AL--Zn--Mg--(Cu)], 8××× series is aluminum and other elements . Generally, each series should be followed by three digits, and each digit should have a number or letter. The meaning is: the second digit represents the number of controlled impurities; the third and fourth digits represent the lowest percentage of pure aluminum and aluminum content after the decimal point. content.
2. According to different processing techniques, it can be divided into cold-rolled aluminum sheet and hot-rolled aluminum sheet.
3. According to different thickness, it can be divided into thin plate and medium plate. The GB/T3880-2006 standard stipulates that the thickness below 0.2 mm is called aluminum foil.
4. According to the surface shape, it can be divided into flat plate and pattern aluminum plate.
