3D Precoated Aluminum for Wall Panels Decoration

Aluminum alloys are classified by alloy composition as follows: High-purity aluminum sheet (rolled from aluminum with a purity of 99.9% or higher) Pure aluminum sheet (primarily composed of pure aluminum) Alloy aluminum sheet (composed of aluminum and auxiliary alloys, typically including aluminum-copper, aluminum-manganese, aluminum-silicon, aluminum-magnesium, etc.) Composite aluminum sheet or welded sheet (aluminum sheet materials for special purposes obtained through the composite of multiple materials) Clad aluminum sheet (aluminum sheet with a thin aluminum sheet clad on the outside for special applications) In aluminum alloys, the grades are representative. Aluminum and aluminum alloys are divided into nine major categories. The 1, 3, 5, 6, and 7 series of aluminum and aluminum alloys are the most common, while other series are less frequently used in practical applications. Category 1: 1 Series: Industrial Pure Aluminum Category 2: 2 Series: Aluminum-Copper Alloys Category 3: 3 Series: Aluminum-Manganese Alloys Category 4: 4 Series: Aluminum-Silicon Alloys Category 5: 5 Series: Aluminum-Magnesium Alloys Category 6: 6 Series: Aluminum-Magnesium-Silicon Alloys Category 7: 7 Series: Aluminum-Zinc-Magnesium-Copper Alloys Category 8: 8 Series: Other Alloys Category 9: 9 Series: Reserve Alloys
