Most people know that aluminum is a light metal that is often used in the construction of things like buildings, airplanes, and automobiles. However, what many people don’t know is that there is a difference between regular aluminum and anodized aluminum. Anodized aluminum is aluminum that has been treated to make it more durable and resistant to corrosion. Let’s take a closer look at the two metals to see what sets them apart.
Aluminum is a metal that is found naturally in the earth’s crust. It is extracted from ore through a process of mining and refining. Once it has been extracted, it can be used in its natural state or alloyed with other metals to create alloys with desired properties. Aluminum alloys are typically used in applications where a lightweight metal is needed, such as in the construction of aircraft or automobiles.
Anodized aluminum has all of these same properties, but with one important addition: a protective coating.
Anodizing is an electrolytic process that improves the corrosion resistance of aluminum by increasing the thickness of its oxide layer. This layer serves as a barrier to prevent moisture and other corrosive elements from coming into contact with the metal underneath. Anodizing also increases the wear resistance of aluminum, making it more resistant to scratches and abrasion. Finally, anodizing can change the colour of aluminum by oxidizing its surface. This process is often used to give aluminum a black or silver finish.
Anodized aluminum can be found in a wide variety of products, from cookware to jewelry to eyeglass frames.
Aluminum vs. Anodized Aluminum: Which Should You Use?
The answer to this question depends on the specific application for which the metal will be used. If the goal is simply to create a light alloy with desired properties, then regular aluminum may be the best choice. However, if corrosion resistance or wear resistance is needed, then anodized aluminum may be a better option. In some cases, both types of aluminum may be used together to achieve desired results. For example, an aircraft may be constructed mostly from aluminum but use anodized aluminum for critical components that are subject to high levels of wear or corrosion.
So, which metal is right for you? If you need a strong, lightweight metal that is resistant to corrosion, then aluminum is a good choice. If you need a metal with all of those same properties plus a protective coating, then anodized aluminum is the way to go.
Aluminum and anodized aluminum are both strong, lightweight metals that are resistant to corrosion. The main difference between the two is that anodized aluminum has a protective coating that makes it more resistant to scratches and fading. So, which one should you choose? It depends on your needs. If you need a strong, lightweight metal that can withstand wear and tear, then anodized aluminum is the way to go. But if you don’t need the extra protection, then regular aluminum will do just fine.
