The cold rolled aluminum coil for anodizing use raw material of cold rolled aluminum coil, then through anodizing, we got the end product-anodized aluminum coil. There are several aluminum alloy can be anodizing. 1060 aluminum coil can be oxidized processing for not very high requirements, after oxidation, the surface is easy to appear color difference, so the cost is low. 1050 and 5052 aluminum foil after oxide processing, there is no color difference, so the cost is slightly higher than 1060 Aluminum coil). Anodized aluminum coil has been widely used in mechanical parts, aircraft, automobile parts, precision instruments and radio equipment, building decoration, machine shell, lighting, consumer electronics, handicrafts, household appliances, furniture, interior decoration, signage, automobile decoration industry.The process of cold rolled aluminum coil for anodizing is: grouding – degreasing – washing – alkali etching – washing – neutralization – wash – anodic oxidation – washing – sealing the hole – washing – test – package. Degreasing, caustic etching, neutralization, anodic oxidation and sealing are the key to ensure the quality of oxidation treatment. Application of cold rolled aluminum coil for anodizing are: Lighting (LED lamp, grille lamp, tunnel lamp, explosion proof lamp and so on). Indoor and outdoor decoration (integrated ceiling). Consumer electronics (laptops, mobile phones, digital cameras, MP3, mobile hard drives, PDA and so on). Household appliances panel (refrigerator panel and lining board, TV rear lining board and base panel, display frame, hood panel and so on). Label (cosmetic packaging, photo frame, logo and so on). Building and solar energy.
