Anodizing
Anodizing is one of the most common surface treatments of aluminum. In all anodizing processes, the basic reaction is conversion of the aluminum surface to aluminum oxide. The aluminum part, when made anodic in an electrolytic cell, causes the oxide layer to become thicker, leading to better corrosion and wear resistance. For decorative purposes, the oxide layer formed on the surface can be dyed.
In aluminum anodizing processes, the basic reaction is a conversion of the aluminum surface to aluminum oxide, including Type I—Chromic acid anodizing, Type II—Sulfuric acid anodizing, Type III—Hard coat anodizing.

FAQ: Anodizing
What is anodizing?
Anodizing refers to a broad range of surface treatments commonly applied to various grades of aluminum and titanium to provide cosmetic and functional benefits.

What is a cold seal?
A cold seal, also known as a room-temperature seal, is a sealing bath that contains nickel and fluoride and is used at ambient temperatures. Best results are obtained with temperature regulation, which ensures a more consistent rate of sealing reaction. Recommended sealing temperatures for Clariant cold seal products are between 80° and 90°F (27° to 32°C).

What is the best anodizing seal process for my operation?
Sealing of anodized aluminum is considered the most important of the various steps in the anodizing process. How you seal determines the performance of the anodic oxide in its end-use environment. After the anodic oxide layer is formed, there are a number of sealing options that exist, including unsealing, high temperature, mid-temperature, and room-temperature or cold sealing.
