Anodizing has become a popular finishing option for aluminum parts. Despite the popularity of aluminum anodizing, there remains a lot of confusion about the process and the resulting finish.
Anodizing refers to an electrochemical process that is used to create an anodic oxide finish on aluminum and other metals. The process is known as anodizing because the aluminum that is being treated serves as the anode in an electrical circuit. The anodizing process actually converts the surface of the metal so that it is smoother, creating an almost decorative appearance that is both durable and resistant to corrosion. Unlike painting or plating, which is applied to the outside of the metal, anodizing creates a finish that is integrated with the aluminum substrate.
The aluminum anodizing process has been used commercially for nearly 100 years, beginning in the 1920s when an early version of anodizing was used to treat the metal used to build seaplanes. The anodizing process has been refined several times throughout the past century, making it simpler, more reliable and more affordable than ever.
There are several benefits to anodized aluminum. The anodic layer of the metal is non-conductive, is more resistant to wear and corrosion than untreated metal, and has improved adhesion for paint or other surface coatings. Anodized aluminum can also be easily powder coated with a variety of colored polyester or epoxy finishes to create a new look. Best of all, the overall strength of the aluminum part is not changed by the anodizing process.
Anodized aluminum is involved in some of the most challenging applications, including the Willis Tower in Chicago – one of the tallest buildings in the world – and even protects satellites in space. Whether for use in construction or commercial goods, anodized aluminum is an excellent option.
