Generally, aluminum materials with a thickness of 0.2mm or more to 500mm or less, a width of 200mm or more and a length of 16m or less are called aluminum plates or aluminum sheets, that is, aluminum plates. According to the alloy composition, the aluminum plates are high-purity aluminum plates (rolled from high-purity aluminum with a content of 99.9% or more), pure aluminum plates, alloy aluminum plates, composite aluminum plates, and aluminum-clad aluminum plates. According to the thickness, we can divide it into thin plates, conventional plates, medium plates, thick plates, and ultra-thick plates.
