Aluminu sheet is a rectangular plate made by rolling aluminum ingots
Aluminum sheet is aluminum materials with a thickness of more than 0.2mm and less than 500mm, a width of more than 200mm, and a length of less than 16m, called aluminum plates or aluminum sheets, less than 0.2mm are aluminum materials, and widths less than 200mm are called rows or strips (of course With the advancement of large-scale equipment, there are more aluminum plates with a maximum width of 600mm).
Aluminum sheet is usually divided into the following two types:
1. According to alloy composition, it is divided into:
High-purity aluminum plate (rolled from high-purity aluminum with a content of more than 99.9)
Pure aluminum plate (components are basically rolled from pure aluminum)
Alloy aluminum plate (composed of aluminum and auxiliary alloys, usually aluminum-copper, aluminum-manganese, aluminum-silicon, aluminum-magnesium, etc.)
Composite aluminum plate or welded plate (special-purpose aluminum plate material is obtained by combining multiple materials)
Aluminum-coated aluminum plate (aluminum plate covered with thin aluminum plate for special purposes)
2. Divided according to thickness: (unit: mm)
Aluminum sheet 0.15-2.0
Conventional board (aluminum sheet) 2.0-6.0
Aluminum plate 6.0-25.0
Thick plate (aluminum plate) 25-200 Extra thick plate 200 or more

14. Chemical/insulation pipe coating.
15. High-quality ship plates
Classification of Aluminum sheet
In aluminum alloys, grades are representative. The following is an example of the grade of 7075T651 aluminum plate. The first 7 represents the aluminum and aluminum alloy group-aluminum zinc magnesium alloy. The aluminum and aluminum alloy group is divided into nine categories. Among them, 1, 3, 5, 6, and 7 series aluminum and aluminum alloys are the main ones, and other series are less likely to be used in actual use.
Category 1: Series 1: Industrial pure aluminum
Category 2: 2 series: aluminum-copper alloy
Category 3: 3 series: aluminum-manganese alloy
Category 4: 4 series: aluminum-silicon alloy
Category 5: 5 series: aluminum-magnesium alloy
Category 6: 6 series: aluminum-magnesium-silicon alloy
Category 7: 7 Series: Aluminum, zinc, magnesium and copper alloys
Category 8: 8 series: other alloys
Category 9: 9 Series: Spare Alloys
