In the world of metal manufacturing, the aluminum circle disc is a fundamental component. These flat, circular sheets are the starting point for thousands of everyday products. From the pots in your kitchen to the reflectors in high-end lighting, these discs play a vital role.
If you are looking for high-quality aluminum circle discs, understanding their specifications is key.
What are Aluminum Circle Discs?
An aluminum circle disc is a circular piece of metal cut from an aluminum coil or sheet. Manufacturers use a process called “blanking” or “punching” to create these shapes.
Because aluminum is soft and easy to shape, these discs are perfect for deep drawing and spinning. This means you can turn a flat disc into a deep pot or a curved lamp shade without breaking the metal.
Technical Specifications: Alloy and Temper
The performance of an aluminum circle disc depends on its chemical makeup. We use different alloys based on how the final product will be used.
Common Alloy Series
Each alloy series has unique strengths. Choosing the right one ensures your product lasts longer and performs better.
| Alloy Series | Main Characteristic | Common Uses |
|---|---|---|
| 1000 Series | $$99%$$ Pure Aluminum | Spinning, lighting, and soft containers. |
| 3000 Series | Manganese added for strength | Professional cookware, non-stick pans. |
| 5000 Series | Magnesium added for corrosion resistance | Pressure cookers, marine parts. |
| 8000 Series | Special alloys | High-strength industrial applications. |
Understanding the Temper (Status)
The “temper” tells you how hard or soft the metal is. This is crucial for manufacturing.
- O (Annealed): This is the softest state. It is perfect for deep drawing where the metal needs to stretch a lot.
- H12 / H14: These are “half-hard” states. They are good for simple bending or flat signs.
- H18: This is fully hard. It is used when the disc must remain very rigid.
Size and Dimensional Range
Precision is everything in manufacturing. We provide aluminum circle discs in a wide variety of sizes to fit any machine or mold.
Standard Dimensions Table
| Specification | Minimum Range | Maximum Range |
|---|---|---|
| Thickness | $$0.3$$ mm | $$6.5$$ mm |
| Diameter | $$20$$ mm | $$1300$$ mm |
| Surface Finish | Mill Finish | Bright / Polished |
| Tolerance | +/- $$0.1$$ mm | +/- $$0.5$$ mm |
Major Application Areas
The aluminum circle disc is used in almost every industry. Here are the most common fields where these discs are essential:
- Cookware Industry: Used to make frying pans, soup pots, pizza trays, and pressure cookers.
- Lighting Industry: Ideal for making recessed lighting, high-bay lamps, and street light reflectors.
- Construction: Used for decorative wall panels and circular architectural elements.
- Signage: Creating round road signs, company logos, and information plaques.
- Transportation: Fuel tank caps and circular covers for trucks and trailers.
- Electronics: Heat sinks and protective covers for circular electronic components.
Different Types of Aluminum Discs
To attract the right customers, we offer specialized types of aluminum circle discs.
1. Deep Drawing Quality (DDQ) Discs
Deep drawing is a process where the metal is pushed into a mold to create a deep shape. Our DDQ discs have a fine grain size. This prevents the “orange peel” effect on the surface of the metal after it is stretched.
2. Spinning Quality Discs
Spinning involves rotating the disc at high speeds while a tool shapes it. These aluminum circle discs are very soft. They allow the craftsman to create elegant curves for vases, lamps, and bowls.
3. Anodizing Quality Discs
If you want to color your aluminum, you need anodizing quality metal. These discs have a very clean surface. Once anodized, the color looks uniform and the metal becomes even more resistant to scratches.
4. Non-Stick Base Discs
These are usually made from the $$3003$$ alloy. They are designed to bond perfectly with non-stick coatings like PTFE or ceramic. They distribute heat evenly, which is why they are the standard for modern frying pans.
Surface Quality and Finishing
The surface of an aluminum circle disc must be perfect. Any scratch on the disc will show up on the finished product.
Mill Finish
This is the standard finish from the rolling mill. It is smooth and clean, ready for most industrial uses.
Bright / Mirror Finish
For high-end lighting, the disc is polished until it reflects like a mirror. This helps the light travel further and look brighter.
Protection with PE Film
To keep the surface safe during transport, we can apply a thin plastic film.
Why Our Aluminum Circle Discs Stand Out
Selecting the right supplier for your aluminum circle disc needs is a big decision. We focus on three main pillars of quality:
Consistent Grain Size
We control the heating and cooling process (annealing) carefully. This ensures the grain of the metal is consistent. Consistent grain means the metal will not crack during deep drawing.
Bur-Free Edges
Our punching machines are high-precision. This means the edges of our discs are smooth and free of sharp “burs.” This makes them safer to handle and easier to put into your machines.
Perfect Flatness
A warped disc can jam a production line. We ensure every aluminum circle disc is perfectly flat. This saves you time and reduces waste in your factory.
Packaging and Delivery
Aluminum is a soft metal. It can dent easily if it is not packed correctly. We take extra care with every order.
- Plastic Interleaving: We can place paper or plastic between each disc to prevent rubbing.
- Silica Gel: We add desiccant bags to the boxes to prevent moisture and “white rust.”
- Strong Pallets: The discs are stacked on reinforced wooden pallets and wrapped in heavy-duty plastic.
- Steel Strapping: We use steel bands to ensure the load does not shift during sea or truck transport.
Frequently Asked Questions (FAQ)
Can I get a custom diameter?
Yes. We have hundreds of molds in stock. If we don’t have your exact size, we can create a custom tool for your project.
What is the Minimum Order Quantity (MOQ)?
For standard sizes like $$300$$ mm or $$400$$ mm, the MOQ is low, usually around $$500$$ kg. For very specialized alloys, it might be higher.
How do I know which alloy to choose?
If you are making simple pans, $$1050$$ is great. If you are making high-end professional cookware, $$3003$$ is much better because it is stronger.
