Black anodized aluminum sheet is a high end anodised aluminum product processed by HC Aluminum with uniform color and static oxidation film. Anodizing of aluminum is an electrolytic oxidation process in which the surface of aluminum and aluminum alloys is usually converted into an oxide film that has protective, decorative, and several other functional properties. In order to overcome the defects of aluminum alloy surface hardness, wear resistance, etc., expand the scope of application, and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloys, and anodizing technology is currently the most widely used and successful method.
Black anodized aluminum sheet involving 1000 series, 3000 series and 5000 series, mainly include 1050, 1100, 3003, 5005, 5052 and 5083 aluminum plates and other key products. HC Aluminum can produce and process the thickness range of 0.2mm-7.0mm, and the width range of 30mm -2650mm, all kinds of anodized aluminum plates with a length of 400mm-8000mm, the produced black anodised aluminum sheet have good adsorption, and can be colored and sealed.
Anodized aluminum sheet production process:
Shelf-degreasing - water cleaning - alkali corrosion - water cleaning - neutralization - water cleaning - anodizing - water cleaning - hole sealing - water cleaning - shelf - inspection - packaging. Deoiling, alkali etching, neutralization, anodic oxidation, grouting reinforcement and other technological processes in the technological process are the key points to ensure the quality of oxidation treatment.
Different black anodized aluminum sheet manufacturers have their own unique features, not necessarily large-scale manufacturers must have advantages over small scale black anodised aluminum plate manufacturers, after all, large scale brand anodized aluminum plate manufacturers have no advantages in terms of ordering and price, but relatively small manufacturers without big brands have a high reputation and each has its own characteristics. HC Aluminum recommends that you choose several manufacturers for comparison when choosing an anodized aluminium sheet manufacturer. It is better to go to the factory workshop to investigate and understand, which is more authentic and well-founded.
