Know why and when to use the two variants of anodized aluminum

As modern architecture evolves, it becomes necessary to choose materials wisely. They help in developing the form and uphold functionality. Aluminum has emerged to be a winner among the variety of options that are available in the market. Among the different varieties of aluminum, bright anodized aluminum and the natural anodized aluminum finish are distinct contributors that help attain aesthetics and structural excellence. 

This guest post revolves around the captivating world of these finishes. From this post, you will learn about their exclusive characteristics, applications, and impact on the industry. 

Know about Bright Anodized Aluminum

Well, bright anodized aluminum is truly a radiant marvel. It stands as a testament to the blend of durability and brilliance. The anodization process reinforces the strength of aluminum. However, that’s not all. It also gives it an eye-catching, shiny finish. The luster is because of the electrochemical oxidation. Besides giving aluminum a shiny, reflective surface, the finish also improves the corrosion-resistant quality of the material.

Properties of bright anodized aluminum

  1. Corrosion Resistant: A major advantage of bright anodized aluminum is that it is exceptionally resistant to corrosion. Therefore, you won’t face any problems when you have to use it for external elements. Thus, when exposed to outdoor elements, they can bear the extremities of the weather. 
  2. Aesthetic Appeal: The bright anodized aluminum has a bright finish. This shine adds a touch of elegance and modernity to various architectural elements. Its reflective surface creates dynamic visual effects. It reflects light as if playing with light and animating the surrounding environment.
  3. Low Maintenance: Do not worry about its aesthetic allure. It doesn’t need much maintenance costs. Thus, you can say that bright anodized aluminum requires minimal maintenance. It comes with a protective oxide layer. This layer is formed during anodization and ensures longevity. Hence, it reduces the need for frequent cleaning. So, you don’t need to spend much to maintain this type of aluminum.
  4. Versatile Nature: Architects and designers admire the versatile nature of bright anodized aluminum. It is highly flexible. It has this remarkable ability to get shaped into aesthetic profiles. Designers can easily integrate it into various architectural styles, which has gained considerable popularity. 
  5. Eco-friendly: Anodizing aluminum is an eco-friendly process. It leads to minimal waste. The aluminum oxide layer that gets deposited is non-toxic. This makes it at par with sustainability, and there is no need for any additional coating.

Applications of bright anodized aluminum

You can witness the use of bright anodized aluminum for various architectural purposes. Some of them are listed below: 

  1. Window Frames: The most common use of bright anodized aluminum is in window frames. The reflective surface allows natural light to penetrate. Also, it gives the window frame a slim and elegant look. 
  2. Doors: Similar to windows, bright anodized aluminum is used in entrances and doors. Its durability ensures safety, and the look upholds modernity.
  3. Cladding Systems: This type of aluminum has a lustrous touch to building facades.
  4. Automotive Components: The bright anodized variety of aluminum is employed in the automotive industry. It is used for trim, accents, and decorative elements on vehicles. 
  5. Consumer electronics: Consumer electronics like mobile phones use bright anodized aluminum in their cases. Thus, they get a sleek appearance.

Know about Natural Anodised aluminum

Natural anodized aluminum is an aluminum surface finish that undergoes the process of anodization. There is no addition of any coloring agent. This leads to the forming of a layer of clear, transparent oxide on the surface of the aluminum. Thus, aluminum has a metallic appearance. The process of anodization involves immersing aluminum in a solution of electrolytes. The aluminum has aesthetically appealing looks and becomes corrosion-resistant. The inherent color of aluminum gets enhanced and gets a shiny appearance.

Properties of natural anodized aluminum

  1. Clear and Transparent Finish: Natural anodized aluminum has an extraordinary metallic finish. The shine of this type of aluminum has reflective properties. Thus, it results in a shiny finish of the aluminum.
  2. Enhanced Corrosion Resistance: The anodizing process results in a protective oxide layer. Thus, it increases corrosion resistance or any other environmental factors. So, natural anodized aluminum is recommended if you want to use something resistant to rust or corrosion.
  3. Uniform Appearance: Natural anodized aluminum is uniform, which most painted or coated finishes lack. Therefore, it looks good and appealing. Due to its uniform appearance, designers and architects choose to use it.
  4. Improved Surface Hardness: Anodization increases the hardness of the aluminum surface. Thus, it helps it become scratch-resistant and improves its overall durability.
  5. Thermal Stability: Natural anodized aluminum has excellent thermal stability. This makes it perfect for applications that are usually exposed to high temperatures.

Applications of Natural Anodized Aluminium

You will find the use of natural anodized aluminum in several fields. Some of them are discussed below:

  1. Architectural Elements: Natural anodized aluminum is commonly used for architectural purposes. These necessities may include exteriors of buildings, curtain walls, and other structures. It has proven to sustain and uphold an elegant appearance in the long run. 
  2. Interior Design: Anodized aluminum has a neutral and metallic look. This is why designers and owners prefer using natural anodized aluminum for interior design elements. It can be used on doors, windows, furniture, etc.
  3. Industrial Components: Natural anodized aluminum’s corrosion-resistant capability and durability make it ideal for industrial applications. They are used in different machinery and equipment components.
  4. Electronics and Technology: As discussed earlier, natural anodized aluminum has a uniform appearance and a clear finish. Therefore, it finds use in the electronics industry as well. It is used in products like components, enclosures, etc.

The Bottom Line

Once you have gone through all the properties of bright anodized aluminum or the one with a natural anodised finish, you decide on the industry where you want to use it. They find use in all fields, like industrial, architectural, and others. Both of these varieties have proved to be game-changers. They are durable and resistant to corrosion and are the best for use.
