CC Aluminum Circle
What Is a CC Aluminum Circle?
A CC aluminum circle is a round aluminum disc made from CC aluminum material. CC stands for Continuous Casting. This is a specific manufacturing process for producing aluminum coils and sheets.
CC aluminum circles are flat, disc-shaped aluminum products. Manufacturers punch or stamp them from CC aluminum coils into precise circular shapes. They are widely used in cookware, lighting, signage, and many other industries.
Understanding the difference between CC and DC aluminum helps you choose the right product for your application.
What Is DC CC Aluminum? – CC vs DC Explained
This is one of the most common questions buyers ask.
What Is CC Aluminum?
CC stands for Continuous Casting and Rolling. In this process, molten aluminum feeds directly into a casting machine. The machine casts and rolls the aluminum into coils in one continuous process.
Key facts about CC aluminum:
- Lower production cost
- Faster production speed
- Suitable for general applications
- Slightly coarser grain structure
- Common alloys: 1050, 1060, 1100, 3003
What Is DC Aluminum?
DC stands for Direct Chill Casting. Molten aluminum pours into a mold and cools rapidly. The cast ingot then goes through multiple rolling processes to reach the final thickness.
Key facts about DC aluminum:
- Higher production cost
- Slower production speed
- Finer grain structure
- Better mechanical properties
- Suitable for high-demand applications
- Common alloys: 5052, 5083, 6061
What Is the Difference Between DC and CC?
| Feature | CC (Continuous Casting) | DC (Direct Chill) |
|---|---|---|
| Process | Continuous casting + rolling | Ingot casting + rolling |
| Cost | Lower | Higher |
| Production Speed | Faster | Slower |
| Grain Structure | Coarser | Finer |
| Surface Quality | Good | Excellent |
| Formability | Good | Excellent |
| Typical Alloys | 1050, 1060, 1100, 3003 | 5052, 5083, 6061 |
| Best For | Cookware, signs, lighting | Marine, aerospace, structural |
| Deep Drawing | Suitable | Better performance |
For most cookware and general aluminum circle applications, CC aluminum is the standard and cost-effective choice.
What Is the Circle of Aluminium?
An aluminum circle is a circular disc cut from aluminum sheet or coil. It is also called:
- Aluminum round circle
- Aluminum circle plate
- Aluminum disc
- Round aluminum blank
Aluminum circles come in many sizes, alloys, and thicknesses. They serve as blanks for further processing such as deep drawing, spinning, stamping, and anodizing.
The most common use is cookware manufacturing. Factories deep-draw aluminum circles into pots, pans, and pressure cookers.

Aluminum Circle – Main Applications
CC aluminum circles work across many industries. Here are the most important ones.
Cookware Manufacturing
This is the largest market for CC aluminum circles.
Manufacturers deep-draw aluminum circles into:
- Cooking pots and saucepans
- Frying pans and woks
- Pressure cookers
- Rice cookers and steamers
- Milk pots and kettles
1060 and 3003 alloys in O temper are the top choices for cookware. They offer excellent deep-drawing performance and food-safe properties.
Aluminum Round Circle for Lighting
Aluminum circles are widely used in the lighting industry.
Common lighting applications:
- Lampshades and reflectors
- LED light housings
- Ceiling light panels
- Street light reflectors
1060 aluminum in bright finish is popular here. The high reflectivity improves lighting efficiency.

CC Aluminum Circle – How It Is Made
Understanding the production process helps you evaluate quality.
Step 1 – Continuous Casting
Molten aluminum feeds into the casting machine. The machine produces aluminum coils in a continuous process. This is the key difference from DC casting.
Step 2 – Cold Rolling
The cast coil goes through cold rolling mills. This reduces thickness to the target specification.
Step 3 – Annealing
For O temper products, the coil goes into an annealing furnace. Heat treatment softens the material for deep drawing.
Step 4 – Slitting
The wide coil is slit to the required width for circle blanking.
Step 5 – Circle Blanking
A stamping press punches circles from the slit coil. The punch and die diameter determine the circle size.
Step 6 – Leveling
Circles pass through a leveling machine. This ensures flatness and removes any warping.
Step 7 – Surface Treatment
Optional polishing, anodizing, or coating is applied at this stage.
Step 8 – Inspection and Packing
Each batch passes dimensional, surface, and mechanical testing. Approved circles are packed with interleaved paper and placed on wooden pallets.
What Is the FCC Structure of Aluminum?
Some customers ask about the FCC structure of aluminum.
FCC stands for Face-Centered Cubic. This is the crystal structure of aluminum at room temperature.
In an FCC structure:
- Aluminum atoms sit at each corner of a cube
- One atom sits at the center of each face
- This structure gives aluminum 12 slip systems
The FCC structure explains why aluminum has:
- High ductility – easy to form and draw
- Good formability – suitable for deep drawing and spinning
- Excellent workability – easy to roll, extrude, and stamp
This is why CC aluminum circles are so easy to deep-draw into cookware and other shapes. The FCC crystal structure allows plastic deformation without cracking.
CC Aluminum Circle Price
What Affects the Price?
Several factors determine the price of CC aluminum circles:
1. Alloy
1060 is the most affordable. 3003 costs slightly more. Higher purity alloys like 1050 fall in between.
2. Temper
O temper requires annealing, which adds processing cost. H-series tempers vary by degree of cold working.
3. Diameter and Thickness
Larger and thicker circles use more material. Price increases with size.
4. Surface Finish
Mill finish is the base price. Bright and anodized surfaces cost more.
5. Quantity
Larger orders receive better unit pricing. MOQ is typically 1–2 tons.
6. LME Aluminum Price
The global aluminum market price changes daily. This directly impacts product pricing.
Estimated Price Range
| Alloy | Temper | Price Range (USD/ton) |
|---|---|---|
| 1060 | O | $2,600 – $3,000 |
| 1060 | H14 | $2,700 – $3,100 |
