What is a "12-Inch" Aluminum Circle?

A 12 inch aluminum circle refers to a flat aluminum disc with a diameter of 12 inches (or other standard dimensions depending on specifications). These circles are typically manufactured from premium aluminum alloys such as the 1000, 3000, 4000, 5000, or 8000 series, known for their excellent formability, durability, and resistance to environmental stress.

At HAOMEI Aluminum, our 12" aluminum discs are produced using advanced cold rolling and annealing processes to meet stringent industrial standards.

Specifications of 12" Aluminum Circles

Aluminum circles can be made from a wide range of alloys from the 1000 to 8000 series, with the most commonly used being:

1000 Series: 1050, 1060, 1070, 1100, 1200

3000 Series: 3003, 3004, 3005, 3105

4000 Series: 4006

5000 Series: 5052, 5083, 5754

8000 Series: 8011

Popular Alloys

1100 Aluminum (Pure Aluminum): High purity, excellent formability and ductility, ideal for deep drawing and spinning, widely used in cookware, lighting reflectors, and bottle caps. Strength is relatively lower.

3003 Aluminum Alloy: Strengthened by manganese, offering higher strength than 1100 series while maintaining good corrosion resistance and formability. Common in cookware (non-stick pans, pressure cookers) and architectural decoration.

5052 Aluminum Alloy: Magnesium alloyed, offering higher strength and excellent corrosion resistance, particularly in marine environments. Common in automotive fuel tanks, aerospace components, and structural applications.

Product Information

Key Features of 12 Inch Aluminum Wafers

1. Lightweight with Low Density
   Aluminum’s naturally low density makes the 12-inch circle lightweight and suitable for weight-sensitive applications such as aerospace parts and electronic housings.

2. Smooth Surface
   Multiple processing steps ensure a flat, smooth surface - ideal for lighting reflectors, food packaging, and other applications requiring high surface quality.

3. Excellent Ductility
   With outstanding elongation, aluminum circles can withstand deep drawing, stamping, and spinning processes, making them ideal for cookware, pans, and container production.

4. Good Electrical & Thermal Conductivity
   Aluminum conducts heat and electricity efficiently, allowing 12" aluminum circles to be used in radiators, circuit boards, and electronic components.

5. Corrosion Resistance
   Properly treated aluminum alloys resist corrosion from moisture, acids, and alkalis, making them suitable for outdoor facilities and chemical equipment.

6. Eco-Friendly & Recyclable
   Aluminum is 100% recyclable, supporting green manufacturing and circular economy goals.

Applications of 12 Inch Aluminum Circle Blanks

12 inch aluminum circle blanks are a very versatile blank material used in a wide range of industries:

12 inch aluminum discs for cookware

Aluminum discs are widely used in cookware due to their low density and light weight. 12-inch aluminum discs can be used to make the bottoms or sides of frying pans, baking pans, and other kitchen utensils, providing uniform heat conduction and a durable surface.

12 inch aluminum discs for cookware

On the road, we often see various circular signs, such as no parking signs, speedometers, and speed limit signs. These signs are typically made from aluminum discs, including 12" ones. They are treated with back reinforcements to ensure durability and legibility. Traffic sign aluminum discs are weather-resistant and durable.

12 inch aluminum discs for electronics

12-inch aluminum discs can be used to make substrates for electronic devices, such as custom parts, components, or machined products requiring a round shape. While ensuring structural strength, they also offer advantages in electrical and thermal conductivity and lightweighting.

12 inch Aluminum Round Sheet for Lighting

Aluminum round billets are often used to make reflectors for lighting fixtures. Their smooth surface effectively reflects light, improving lighting efficiency. They can also be used as lamp housings, providing excellent heat dissipation and aesthetics.

Aluminum Circle Size Specifications

1 inch = 2.54 cm, so a 12" circle equals approximately 304.8 mm in diameter.

Thickness typically ranges from 0.5 to 6.0 mm, and custom production can be performed to meet specific customer needs. Strict dimensional tolerances are maintained during production to ensure product consistency and interchangeability.
