Aluminum plate is usually divided into the following two types:
1.According to thickness :(unit: mm)
Sheet (aluminum sheet) 0.15-2.0
Conventional sheet (aluminum sheet) 2.0-6.0
Medium plate (aluminum plate) 6.0-25.0
Thick plate (aluminum plate) 25-200 super thick plate 200
2.According to the composition of alloy:
In the aluminum alloy brand is representative, the following is based on 7075T651 aluminum plate brand as an example. The first 7 represents aluminum and aluminum alloy groups – al-Zinc-mg alloys. Aluminum and aluminum alloy groups are divided into nine major categories. Among them, 1, 3, 5, 6, 7 series of aluminum, aluminum alloy is the main, and the 1 series and 3 series of aluminum plate is the most commonly used, other series are rarely used in actual use.
Technical quality requirements of aluminum plate:
1.The most basic point is that the surface of the plate must be clean, do not allow cracks and some other oxidized debris.
2.Due to the imperfections of the process caused by the plate surface is allowed to have depression, scratch or roller indentation and other defects, but the depth of the plate must not exceed the allowable negative deviation, more than the deviation value will be re-made.
3.Process aluminum coated thick plate to allow the peeling part of the coating layer and the bubble of the coating layer.
4.Plate surface under normal circumstances is allowed to remove the defects in the thickness difference range.
5.Other requirements are mainly with the demand of the suppliers and their own draft, and then change the production process.
The above is about the quality requirements of the aluminum plate surface. Although there will be a certain error for some reasons, it must not exceed the controllable deviation value.
