BRUNNER ENTERPRISES
AMERICA‘S PREMIER DISTRIBUTOR OF ALUMINUM EXTRUSIONS
Anodizing is a technique that enables metal to develop a layer of oxide on its surface by submerging it in an electrolyte solution and applying an electric current. This process gets its name from the fact that the treated piece acts as the anode in the electric circuit. Depending on the specific alloy and the desired thickness of the coating, anodizing can enhance the metal’s hardness, corrosion resistance, and even alter its thermal or electrical properties. Many aluminum extrusions, like those from Brunner Enterprises™ Inc., are often anodized for added strength or aesthetic appeal.
HOW DOES IT HAPPEN?
The anodizing process starts with cleaning the aluminum piece as it exits the extruder. This step removes any contaminants on the surface, preparing it for the next phase, where an electric current is passed through a part known as the cathode. As a result, hydrogen forms on the cathode, while a layer of oxygen builds up on the anode, leading to the creation of an oxide layer that prevents further oxidation.
To the naked eye, the oxide layer appears smooth and glossy, providing an appealing finish. However, a closer look reveals a network of tiny fissures that enable dyes to seep beneath the surface, resulting in vibrant, glossy, and long-lasting colors. While these fissures enhance aesthetic qualities, they can also allow corrosive substances to reach the underlying metal, which may necessitate additional protective coatings to prevent corrosion.
ALUMINUM ALLOYS
Aluminum alloys are particularly suitable for anodizing because the alloying process often diminishes aluminum’s natural ability to undergo passivation. Since passivation is crucial for corrosion resistance, the inability to passivate leaves alloys more vulnerable to corrosion. Anodizing not only restores this protective layer but also grants the alloys similar corrosion resistance to pure aluminum.
In both industrial and artistic applications, anodized metals, especially aluminum, are indispensable. Anodized aluminum extrusions often feature as panels on building exteriors, railings, and various outdoor elements. Household appliances, including refrigerators, microwaves, and televisions, frequently use anodized aluminum casings. Additionally, items like vent covers, awnings, and light fixtures exploit the metal’s weather-resistant qualities. Its corrosion resistance makes it an excellent choice for kitchenware, such as pots and pans.
