The performance comparison of the  aluminum composite panel , In the process of  aluminum composite panel processing, all kinds of alloying elements are added to achieve some special mechanical properties of aluminum composite panel . The 1000 series is pure aluminum plate, for example, the main composition of 1060.  aluminum composite panel is aluminum, which reaches more than 99%. The alloy aluminum plate can be roughly divided into 7 series, which are 2-8 series respectively. For example, 2A21 belongs to the 2 series 3003 belonging to the 3 Series 5052 belonging to the 5 series.
