Anodized Aluminum Coil

After the anodized aluminum coil is anodized, there is an oxide layer with a thickness of 3-20um. Different alloys, states, specifications, weights, and packages can be customized. The longer the processing time, the thicker the alumina layer, the whiter the surface color, the higher the price, and the higher the market. Oxide layer 3μm and below, mainly used for waterproofing, such as air conditioners, refrigerators, etc.; 5-6μm, mainly used for surface technology, used for spraying and color coating processes, such as license plates, curtain walls, interior decoration, signs, advertising boards, etc.; 6 -10μm, due to its high strength and corrosion resistance, it is widely used, mainly used in machine shells, lighting, consumer electronics, handicrafts, household appliances, interior decoration, furniture, automobile decoration and other industries; 20μm, shipbuilding, aircraft, electrical components, etc.
