Aluminum round circle (also called aluminum discs or blanks) are precision-cut circular aluminum sheets used across manufacturing industries. These versatile components come in various diameters and thicknesses, offering excellent machinability and corrosion resistance for multiple applications.






What is an Aluminum Round Circle?
An aluminum round circle is a flat, circular sheet made from aluminum. It is commonly used as raw material for cookware, automotive parts, packaging, and other manufacturing needs. The round shape allows easy molding and further processing.
Classification of Aluminum Round Circles

Aluminum round circles can be classified based on their surface finish, size, and alloy type. Here is a table showing common classifications:
| Classification Type | Description | Typical Diameter Range (mm) | Surface Finish |
|---|---|---|---|
| Mill Finish | As produced by rolling, no extra treatment | 100 – 1000 | Matte, untreated |
| Polished Round Circle | Polished for glossy or mirror finish | 100 – 800 | Shiny, reflective |
| Anodized Round Circle | Anodized for corrosion and aesthetic | 100 – 900 | Colored or clear matte finish |
| Embossed Round Circle | Patterned surface | 100 – 700 | Textured |
Thickness of Aluminum Round Circles
Thickness plays a key role in choosing the right aluminum round circle, depending on the application. The most common thickness ranges include:
| Thickness (mm) | Application Examples |
|---|---|
| 0.1 – 0.3 | Packaging, beverage can lids |
| 0.3 – 0.8 | Cookware, automotive parts |
| 0.8 – 1.5 | Electrical cans, decorative panels |
| 1.5 – 3.0 | Heavy-duty industrial parts, structural components |
Alloy Types for Aluminum Round Circles
Selecting the correct aluminum alloy is important for strength, flexibility, and corrosion resistance. Common alloys used for aluminum round circles include:
| Alloy Series | Features | Typical Uses |
|---|---|---|
| 1xxx Series | Pure aluminum, excellent corrosion resistance | Packaging, chemical industry |
| 3xxx Series | Good corrosion resistance, moderate strength | Cookware, roofing, siding |
| 5xxx Series | High strength, good weldability | Automotive, marine parts |
| 6xxx Series | Medium strength, good machinability | Electrical panels, structural parts |
Packaging of Aluminum Round Circles
Proper packaging ensures the aluminum rounds reach you in perfect condition. Packaging types often depend on size, thickness, and shipment method:
- Pallet Packaging: Stacked flat on wooden or metal pallets, secured with straps
- Plastic Wrapping: To protect surface from scratches and moisture
- Inner Paper Sheets: Between circles to avoid metal-to-metal contact
- Custom Boxes: For smaller or precision products
Applications of Aluminum Round Circles
Aluminum round circles are used in various industries due to their versatile properties:
- Cookware manufacturing (pots, pans, lids)
- Automotive parts (discs, covers)
- Packaging (bottle caps, cans)
- Electrical industry (panels, connectors)
- Decorative products (medallions, plaques)
- Construction (roofing, siding components)
How to Choose the Right Aluminum Round Circle?
When selecting aluminum round circles, consider these factors:
- Size and Diameter: Based on the final product requirement
- Thickness: Thin sheets for packaging; thicker for structural use
- Alloy: Select alloy based on strength and corrosion needs
- Finish: Choose surface finish for aesthetic and functional performance
- Quantity and Packaging: Consider packaging based on transportation and storage
