The practice of anodizing, or controlled oxidation, of aluminum and its alloys has been around for more than seven decades. The main intention behind anodizing aluminum and its alloy parts is to protect the highly reactive surface against corrosion in aqueous environments, such as humid air and seawater. Since anodic coating can be produced in a range of colors, painted parts are generally used in architectural applications. Additionally, as the AC aluminum anodizing process would produce a hard ceramic coating, harder than the substrate from which it is formed, anodic coatings are also used to protect aluminum parts from abrasions, especially sand abrasion. The traditional anodizing process is electrochemical oxidation. The part to be anodized is then connected to the positive terminal of a direct current (DC) power source and a non-reactive metal, such as stainless steel, is attached to the negative terminal. The aluminum anode and the stainless steel cathode are then immersed in a
Being an amazing metal, aluminum weighs a third of steel, does not burn, is not magnetic, and has high inherent resistance to corrosion, and will get stronger as it cools. Of the common metals, by weight, aluminum is the most efficient thermal conductor. Since its introduction to the world, anodizing has been recognized as a valuable means of extending the life of aluminum. Anodizing will enhance the use of this metal as a lightweight and attractive manufacturing component. While the science of anodizing aluminum is well known, the actual practice of anodizing and the resulting finished product often varies from one anodizing company to another. So the most important thing everyone needs to know about this is how to choose the aluminum anodizing at CA Company that is most capable of delivering results that are acceptable to you and your business. To understand the anodizing company selection process, it will be helpful to have a basic understanding of the aluminum anodizing process i
