Materials and Finishes Available for Extruded Aluminum Profiles

Extruded aluminum profiles offer a wide range of material and finish options to meet diverse design and performance requirements. Understanding these options is crucial for selecting the most appropriate solution for any given application.

Materials:

6000 Series Alloys

The most common choice for extruded aluminum profiles, 6000 series alloys combine strength, corrosion resistance, and weldability. They are typically used in architectural, industrial, and automotive applications.

7000 Series Alloys

7000 series alloys offer superior strength and hardness compared to 6000 series alloys. They are frequently employed in aerospace, defense, and transportation industries where high structural integrity is essential.

2000 Series Alloys

2000 series alloys are known for their high copper content, resulting in increased strength and hardness. They are often used in aircraft components and marine applications.

5000 Series Alloys

5000 series alloys provide a balance of strength and corrosion resistance. They are commonly found in automotive, marine, and architectural applications where moderate structural performance is required.

Finishes:

Anodizing

Anodizing is an electrochemical process that creates a protective and decorative oxide layer on the aluminum surface. Anodized finishes can vary in color, thickness, and texture, offering a wide range of aesthetic and functional options.

Powder Coating

Powder coating involves applying a dry paint powder to the aluminum profile, which is then baked to create a durable and color-resistant finish. Powder coatings are available in a vast array of colors and textures, including metallic, matte, and high-gloss.

Painting

Painting is a traditional method of finishing aluminum profiles. It offers flexibility in terms of color selection and can be customized to meet specific project requirements. However, painted finishes may be less durable than anodized or powder-coated finishes.

Electrophoresis

Electrophoresis is a process that deposits a water-based paint onto the aluminum surface using an electrical current. This method provides a uniform and corrosion-resistant finish with excellent adhesion and scratch resistance.

Clear Coat Sealing

Clear coat sealing involves applying a transparent protective layer to the aluminum surface. It enhances the natural appearance of the metal while providing additional corrosion resistance and UV protection.

The choice of materials and finishes for extruded aluminum profiles requires careful consideration of factors such as strength, durability, corrosion resistance, and aesthetics. By understanding the available options, designers and engineers can select the most suitable solution for their specific applications.
