Black aluminum coil advantages and application A black aluminum coil is a kind of coated aluminium coil stocks processed by color coating or anodizing methods. A coated aluminium coil has PE or PVDF coating on the surface, obtained by sending mill finish aluminum coil stocks into painting rollers, and an anodized aluminum roll has a film layer. The thin layer of the oxide film has a large number of micro pores, which can absorb various lubricants and pigments, and can be colored into various beautiful and beautiful colors. Almost all grades of aluminum coil rolls can be made into black color coated aluminum coil. A black coated aluminium coil usually falls on two types: PE coated and PVDF coated coil, although sometimes PVC coil is demanded. The PE paint is cheaper and poorer in performances than PVDF, but it covers an equivalent wide scope of application, such as interior decoration, wall cladding, advertising, cookware, lamps, electronic products, home appliances and so on. Roofing proves to be an important part in application of of the coil, made of 3003 or 3004 aluminium alloy of H14 and H24. Black painted aluminum coil rolls, withstanding corrosion, oxidation, sunshine and extreme temperatures without deformation or color fading, winning increasing popularity as a wall cladding and electronic material, too. A black anodized aluminum coil roll is applied in machinery parts, aircraft and auto parts, precision instruments and radio equipment, architectural decoration, machine shells, lighting, electronic consumer goods, handicrafts, household appliances, interior decoration, signs, furniture, automotive decoration and other industries. In detail, black anodized aluminum coil suppliers take pride in their products for the following advantages. First, outstanding weather resistance. Anodized aluminium rolls rank top in resisting abilities against color fading, erosion, oxidation etc.. Second, strong metal sense. Different from a coated black aluminum coil roll, a black anodized alu coil has no paint on the surface but a natural metal gloss, just as no surface treatment has been made. Third, high surface hardness. The hard anodized film of the roll mixes perfectly with the aluminium metal itself and acts as a protective layer against scratches. Fourth, environmental friendly. No toxic gases will be generated even though an anodized aluminium coil is under high temperature, for it has obtains the black color by pure chemical methods rather than adding extra elements onto the coil surface. In general, black anodized aluminum coil rolls are higher in price than coated rolls.
