All About Anodized Aluminum

When it comes to metalwork, there are a variety of finishes and coatings that can be applied to aluminum in order to achieve a desired look or functionality. One key option available is the highly reliable, highly durable anodized aluminum. Offering tremendous benefits to your project, anodized aluminum can and will be the difference maker for your next build. But what exactly is anodized aluminum, how is it created, and what does it offer?

What is Anodized Aluminum?

Anodized aluminum is aluminum that has been subjected to an electrolytic process in order to increase its thickness. This process causes a thin layer of aluminum oxide to form on the surface of the metal, which acts as a barrier against corrosion. Anodized aluminum is often used for architectural applications such as window frames, curtain walls, and handrails, industrial purposes such as machine parts and conveyor belts, and exterior applications such as wall cladding and roofing.

How is Anodized Aluminum Made?

In order to anodize aluminum, the metal must first be cleaned and placed in an electrolyte solution. A direct current is then passed through the solution, causing the oxidation reaction on the surface of the aluminum. The thickness of the anodized layer can be controlled by varying the current density, duration of the process, and type of electrolyte used. This creates a thick oxidized layer that offers significantly more durability than the base aluminum material.

Key Benefits of Anodized Aluminum

There are several key benefits that come with using anodized aluminum:
Increased durability: The anodizing process creates a harder surface on the aluminum that is more resistant to wear and tear.
Improved aesthetic: Anodized aluminum can be dyed in a wide range of colors, giving it a unique appearance that can be customized to suit your needs.
Enhanced corrosion resistance: As we mentioned earlier, the formation of the anodized oxide layer provides increased protection against corrosion.
Greater sustainability: Anodizing is an environmentally friendly process that does not use any harmful chemicals or produce any toxic waste products, ensuring aluminum’s continued sustainability.

As you can see, there are many reasons why you might want to consider using anodized aluminum for your next project.
