Aluminum sheets are usually divided into the following two categories:

1. According to the alloy composition is divided into:

High-purity aluminum plate (rolled from high-purity aluminum with a content of more than 99.9)

Pure aluminum plate (the composition is basically rolled from pure aluminum)

Alloy aluminum plate (composed of aluminum and auxiliary alloys, usually aluminum-copper, aluminum-manganese, aluminum-silicon, aluminum-magnesium, etc. series)

Clad aluminum plate or welded plate (special purpose aluminum plate material is obtained by means of compounding various materials)

Aluminum-clad aluminum sheet (the outer side of the aluminum sheet is covered with thin aluminum sheet for special purposes)

2. According to thickness: (unit mm)

Sheet (aluminum sheet) 0.15-2.0

Conventional sheet (aluminum sheet) 2.0-6.0

Aluminum plate 6.0-25.0

Thick plate (aluminum plate) 25-200 Ultra-thick plate above 200
