What Is an Aluminum Disc?
An aluminum disc (also called aluminum circle or aluminum round blank) is a flat, circular piece of aluminum cut or stamped from aluminum sheet or coil.
Aluminum Disc Specifications & Parameters
Before placing an order, buyers should review the key technical parameters. The table below covers the most common specifications:
| Parameter | Details |
|---|---|
| Alloy Grade | 1050, 1060, 1100, 3003, 5052, 6061 |
| Temper | O (annealed), H12, H14, H18, T6 |
| Diameter | 80 mm – 1,500 mm (custom sizes available) |
| Thickness | 0.3 mm – 10 mm |
| Surface Finish | Mill finish, anodized, mirror finish, polished |
| Edge Treatment | Sheared edge, milled edge |
| Standard | ASTM B209, EN 573 |
| MOQ | 500 kg (typical for factory orders) |
For buyers needing specific sizes such as a 4 inch aluminum disc, 3 inch aluminum disc, or a 12 inch aluminum disc, custom stamping is available from most manufacturers with short lead times.
Common Alloy Grades for Aluminum Disc
Not all aluminum discs are the same. Choosing the right alloy grade is critical for performance and cost.
1050 / 1060 / 1100 Aluminum Disc These are pure aluminum series (99%+ aluminum content). They offer excellent formability, good electrical conductivity, and superior corrosion resistance. They are the most popular choice for cookware, road signs, and lighting reflectors. The 1050 aluminum disc and 1100 aluminum disc are widely used in spinning and deep drawing processes.
3003 Aluminum Disc 3003 adds a small amount of manganese for improved strength while maintaining good workability. It is commonly used for pressure vessels, cookware lids, and chemical tanks.
5052 Aluminum Disc 5052 offers higher strength and excellent corrosion resistance, especially in marine environments. It is a good choice for structural and industrial applications.
6061-T6 Aluminum Disc 6061-T6 is a heat-treated structural aluminum alloy with high mechanical strength. It is used in precision machining, aerospace components, and high-performance parts where strength matters most.
Alloy Comparison Table
| Alloy | Tensile Strength (MPa) | Formability | Corrosion Resistance | Typical Use |
|---|---|---|---|---|
| 1050 / 1060 | 60–95 | Excellent | Excellent | Cookware, signs, lighting |
| 1100 | 90–125 | Excellent | Excellent | Deep drawing, spinning |
| 3003 | 110–145 | Good | Very Good | Cookware lids, tanks |
| 5052 | 170–230 | Moderate | Excellent | Marine, structural |
| 6061-T6 | 276–310 | Moderate | Good | Machining, aerospace |
Round Aluminum Disc: Size Guide
Round aluminum discs come in a wide range of diameters. Below is a reference size guide for common buyer requests:
| Common Name | Diameter | Typical Thickness | Common Alloy |
|---|---|---|---|
| 3 inch aluminum disc | 76.2 mm | 1.0 – 3.0 mm | 1100, 3003 |
| 4 inch aluminum disc | 101.6 mm | 1.0 – 4.0 mm | 1100, 6061 |
| 12 inch aluminum disc | 304.8 mm | 1.5 – 6.0 mm | 1050, 5052 |
| 24 inch aluminum disc | 609.6 mm | 2.0 – 8.0 mm | 1060, 5052 |
| Custom large disc | Up to 1,500 mm | Up to 10 mm | All grades |
Custom diameters are available. Most factories cut aluminum discs to exact size using CNC punching or laser cutting.
What Is an Aluminum Disc Used For?
The aluminum disc has a very broad range of industrial and consumer applications. Here are the most important ones:
Cookware & Kitchen Utensils
This is the largest end-use market for aluminum discs worldwide. An aluminum circle for utensil production is typically made from 1050, 1060, or 3003 alloy in annealed (O temper) condition. The discs are deep drawn or spun into pots, pans, pressure cooker lids, and woks.
Cookware manufacturers in Europe, the Middle East, Africa, and Southeast Asia all rely on aluminum disc suppliers for continuous supply.
Road Signs & Traffic Signs
Flat aluminum discs and aluminum circle plates are used as blanks for road signs, parking signs, and information boards. The 1060 or 5052 alloy is preferred for its weather resistance and light weight.
Lighting & Reflectors
Highly polished or mirror-finished aluminum discs are used in LED lighting reflectors, solar reflectors, and stage lighting. The high reflectivity of pure aluminum alloys (1050, 1060) makes them ideal for this purpose.
cts labeled for non-ferrous metals.
Anodized Aluminum Discs
Anodized aluminum discs have an electrochemical oxide layer on the surface. This layer improves hardness, corrosion resistance, and allows coloring (black, silver, gold, red, blue).
Electronics & PCB Components
Aluminum discs serve as heat spreaders and substrates in LED PCB assemblies. The colored aluminum disc and anodized variants are also used in electronic enclosures and connectors.
Aluminum Disc vs. Aluminum Plate: What’s the Difference?
Many buyers search for both aluminum disc and aluminum plate. Here is a quick comparison:
| Feature | Aluminum Disc | Aluminum Plate |
|---|---|---|
| Shape | Circular | Rectangular / square |
| Typical use | Cookware, signs, spinning | Structural, fabrication |
| Production method | Punching / stamping / cutting | Rolling |
| Edge finish | Clean sheared or milled | As-rolled or saw-cut |
| MOQ | Lower (500 kg) | Flexible |
How to Choose the Right Aluminum Disc
Follow these steps to select the correct aluminum disc for your project:
- Define the application — cookware, sign, machining, abrasive use?
- Select the alloy — 1050/1060 for deep drawing; 6061-T6 for machining; 5052 for marine.
- Confirm the diameter and thickness — standard sizes are faster and cheaper; custom sizes require a minimum order.
- Choose surface finish — mill finish for further processing; anodized or mirror finish for end use.
- Check temper — O temper for forming; T6 for strength; H14/H18 for harder surfaces.
- Request a sample — reputable factories provide samples before bulk orders.
Aluminum Disc Price Factors
The price of an aluminum disc depends on several factors:
| Factor | Impact on Price |
|---|---|
| Alloy grade | 6061 > 5052 > 3003 > 1100 > 1060 > 1050 |
| Thickness | Thicker = more material cost |
| Diameter | Larger = more waste during stamping |
| Surface finish | Anodized / mirror finish adds cost |
| Order quantity | Larger orders reduce unit price |
| Market aluminum price | LME aluminum price fluctuates daily |
For current pricing, contact the manufacturer directly with your exact specifications.
