What is Anodized Metal? 7 Uses for This Hard Aluminum Metal

What is Anodized Metal?

Aluminum is one of the few metals that is made stronger through the oxidation process. Oxidation is the process that causes rusting, so for most other metals this is a cause of deterioration. So, what is anodized metal? It is the strengthening process aluminum goes through is called anodizing, which usually involves a bath of acetone that induces electrical currents.

Ultimately, it can result in aluminum that is harder than diamonds. It is often used in harsh environments or in applications that require exposure to the elements. The hard coating that results from the process replaces the original substance. Plus it does not flake off like normal rust, so it can be used in many applications.

Will Anodized Aluminum Rust?

anodized aluminumAnodized aluminum is aluminum that has been submerged in a chemical acid bath, causing an electrical current to run through it. This electrical current oxidizes, or rusts, the surface and creates a protective film. Because of that, anodized aluminum does rust but not in a typical way, and more importantly not in a harmful way. It has increased resistance to corrosion and wear. The anodizing process can work on almost any non-ferrous metal, such as tantalum, titanium, zinc, and magnesium.

Anodized Aluminum Sheet

Anodizing does not just increase the durability of an anodized aluminum sheet—it heightens the visual appeal too. The oxide layers added by anodizing make the aluminum surface better for dyes, adhesives, and paint. Anodized aluminum nameplates allow the image to be sealed in anodized aluminum. This ability makes for superior image appearance with lasting quality.
