Aluminum coil for alu composite panel

Aluminum coil for alu composite panel can be of 1xxx, 3xxx and 5xxx series. After being treated by coating or anodizing process, it combines plastic materials to form panels for construction and decoration. This combination of two materials (metal and non-metal) not only retains the main characteristics of the original constituent materials (metal aluminum, non-metal polyethylene plastic), but also overcomes the shortcomings of the original constituent materials, adding more positive properties to aluminum coil sheet products, such as luxury, colorful decoration, weather resistance, corrosion resistance, impact resistance, fire resistance, moisture resistance, sound insulation, heat insulation, shock resistance, light weight, easy processing and forming, easy handling and installation, and so on. As a result, these panels enjoy an even wider application scope than aluminium coil itself, including curtain walls, ceiling, wall cladding, sound insulation panels for land vehicles and planes, office partitions, furniture, decorative panels for cars etc.

1xxx and 3xxx aluminum coil rolls are the most widely applied aluminum coil for composit panel products. These are two series of aluminium products with different properties. 1xxx is also known as pure industrial aluminum, featured by low hardness, good elongation and satisfying corrosion resistance. It has the poorest properties as a surface material for composite panels, but this can be improved by anodizing and color coating, which endows it with a hard protective layer on the surface.

The other series adopted as a raw material for composite panels is 5xxx, including aluminum coil 5182 5052 5754 etc. Different from 3xxx series that contain manganese, 5xxx coil rolls have magnesium as their alloying metal. Magnesium is lighter and more corrosion resistant than manganese, and its composition with aluminium brings about an even stronger hardness, making 5000 aluminium an excellent marine grade aluminum plate material. While being used as a composite material, it displays powerful weather resistance and long service life.
