Properties of Aluminum Circle

Easy Maintenance

Aluminum Circles feature a smooth surface that is easy to clean. Surface treatments such as anodizing or coating enhance corrosion resistance and reduce cleaning frequency, making them ideal for applications requiring low maintenance and long-term durability.

Easy Processing

Aluminum Circles exhibit excellent formability and can be easily cut, stamped, or machined. They are ideal for industrial applications that require high precision and production efficiency.

Light Weight

Aluminum Circles are lightweight and offer sufficient strength for forming and fabrication, making them ideal for applications where reduced weight contributes to improved performance and lower energy consumption.

Aluminum Surface Finishes & Protection

Surface Finishes Description Features Protection
Mill Finish The natural finish of aluminum after rolling, without additional processing. Non-uniform reflectivity, and a slightly rough surface with a matte or dull metallic sheen. Paper interleaved, PE/PVC filming (if specified)
Anodizing An electrochemical process that thickens the natural oxide layer on the aluminum surface. Enhances corrosion resistance, hardness, and allows for coloring.
Polished Finish Polished aluminum is mechanically buffed to achieve a mirror-like surface without any protective coating. A smooth, mirror-like surface with high reflectivity and a bright silver hue, offering a sleek and decorative finish.
Brushed Finish The surface is mechanically polished to create a uniform satin texture. A linear texture and reduced reflectivity for a decorative feel.
Color-Coated Finish Produced by applying a layer of durable paint in various colors onto the aluminum surface. It offers excellent resistance to corrosion, UV radiation, and long-lasting color, while enhancing the material's aesthetic versatility.

Packaging of Aluminum Circle

Surface Protection Waterproof Sealing Securing and Palletizing
The surface of Aluminum Circles is covered with a protective layer of polyethylene (PE) film, laser film, or oil to prevent oxidation and dirt accumulation. Aluminum Circles are securely wrapped in waterproof materials, including plastic film, shrink wrap, or waterproof kraft paper. Desiccants may be placed inside the packaging to prevent moisture buildup. The wrapped Aluminum Circles are securely strapped to wooden or metal pallets using durable steel or plastic bands, ensuring stability and safety in transit.
