While these keywords are frequently used by buyers from different regions, they generally refer to the same round aluminum product.

Aluminum Circle Plate Specifications

Aluminum circles are usually cut from aluminum coils or aluminum sheets. Depending on different applications, they are available in various sizes and temper grades.

For special sizes or technical requirements, please send your drawing or specification to our sales team through the Contact Us page.

Available Aluminum Circle Plate Alloys

Selecting the appropriate aluminum alloy “grade” is critical to the manufacturing process:

• 1050 / 1060 / 1100 / 1070: These are “pure” aluminum alloys. They are very soft with excellent ductility, making them ideal for complex spinning or deep drawing processes and less prone to cracking.
• 3003: The addition of manganese gives this alloy higher strength than the 1000 series aluminum alloys. It is the “workhorse” of the cookware industry because it combines strength with good formability.
• 5052: Contains magnesium, offering high strength and excellent marine-grade corrosion resistance. It is commonly used for structural components or road signs.

Available Aluminum Circle Plate Tempers

Haomei Aluminum supplies aluminum circle plates in multiple temper conditions to match different manufacturing processes and finished product requirements. Choosing the proper temper helps improve forming performance, production efficiency, and finished product quality.

O (Fully Annealed) H12 H14 H18 H24

O temper is widely selected for deep drawing and spinning because of its excellent ductility. H12 and H14 provide a balance of strength and formability for general stamping applications, while H18 offers higher hardness for products requiring greater rigidity. H24 is commonly used where moderate strength and good forming performance are both required.

If your application involves cookware, lighting reflectors, traffic signs, electrical components, or other custom fabricated parts, our technical team can recommend the most suitable alloy and temper based on your production process, drawing depth, strength requirements, and surface finish expectations.

Surface Finish Options for Aluminum Circle Plates

The surface condition of an aluminum circle plate directly affects its appearance, forming performance and suitability for later processing. For cookware, lamp reflectors, decorative parts and coated products, choosing the right finish can help reduce production loss and improve the final product quality.

• Mill finish aluminum circle plate
• Bright aluminum circle disc
• Brushed aluminum round disc
• Polished aluminum circle plate
• Color coated aluminum circle sheet
• PE / PVC film-protected surface
• Dry surface or light-oiled surface on request

Each batch is checked before packing to help avoid visible defects such as deep scratches, oil stains, oxidation spots, dents, uneven color and sharp edge burrs. Protective paper, film or suitable packing can also be used when the application requires a cleaner surface.

If the aluminum circles will be used for anodizing, deep drawing, polishing, painting or non-stick coating, please share your processing method with us before ordering. Our team can recommend a suitable alloy, temper and surface condition to match your production requirements.

Aluminum Circle Plate Tolerance Control

Stable tolerance helps customers improve production efficiency and reduce waste during stamping, drawing or spinning.

General tolerances depend on alloy, temper, thickness and diameter. For strict tolerance requirements, please provide your technical drawing or standard before quotation.

Our quality team checks aluminum circle plates during production and before packing to make sure the goods meet order requirements.

Aluminum Circle Plate Applications

Aluminum circle plates are widely used across multiple industries:

• Cookware and kitchenware: Pots, frying pans, lids, baking trays. High-formability alloys such as 1070 in O temper are ideal choices.
• Lighting: Due to aluminum’s high reflectivity, it is commonly used to manufacture reflectors, lamp shades, and LED housings.
• Signage: Round traffic signs, nameplates, and street signs (typically 1000 or 3000 series).
• Electronics and electrical: Heat sinks, enclosures, capacitors. High-thermal-conductivity alloys such as the 1100 series are preferred.
• Packaging industry: Food containers, aerosol cans, beverage cans (aluminum can ends).
• Industrial and machinery: Circular plates used for tanks, drums, chimneys, and chemical processing equipment.
• Decoration and construction: Ceiling panels, architectural components (anodized or brushed surface finishes).
• Automotive: Wheel rims, fuel tank components, and heat shields.

Cookware Aluminum Circle Plate

In the cookware industry, aluminum is highly favored for its fast and even heat conduction. These circles are typically processed into pots, frying pans, and pressure cookers through deep drawing or spinning.

Aluminum circle plate is widely used in cookware manufacturing. It can be processed into frying pans, non-stick pans, cooking pots, sauce pans, rice cooker inner pots, kettles, kitchen bowls and bakeware.

For cookware applications, 1050, 1060, 1100 and 3003 aluminum circles are commonly used. O temper and soft tempers are preferred for deep drawing and spinning.

Lighting Aluminum Circle Plate

Aluminum circles are standard materials for manufacturing lamp reflectors and shades. They can be polished to a mirror finish, making them ideal for controlling light direction.

Aluminum circle discs are used for lighting products due to their good thermal conductivity and surface performance.

Common lighting applications include lampshades, reflectors, LED lamp covers, downlight components and decorative lighting parts. Surface quality and flatness are especially important.

Aluminum Circle Plate for Road Sign

Traffic signs and road signs require durability and the ability to remain rust-free in harsh outdoor environments.

Aluminum circle plate and aluminum circle sheet are suitable for round traffic signs and road signs. Aluminum is lightweight, corrosion-resistant and easy to coat or print.

Common sign applications include traffic signs, warning signs, road safety signs, directional signs and industrial signs. H14 or H18 temper is often used when higher hardness and flatness are required.

Spinning Aluminum Circle Plate

“Spinning” refers to a metal forming process in which a disc is rotated at high speed on a lathe and shaped over a mandrel using roller tools.

Aluminum Circle Plate Advantages

How to Choose an Aluminum Circle Plate

Choosing the right aluminum circle plate (also known as aluminum discs or blanks) mainly depends on your manufacturing process—such as spinning, deep drawing, or stamping—and the final application of the product.

Select the Right Aluminum Alloy

The alloy determines the strength, corrosion resistance, and thermal conductivity of the circle.

Choose the Proper Manufacturing Process (CC vs. DC)

CC Aluminum Circle Plate: Best for spinning. It is generally more cost-effective but may have slightly less consistent grain structure for complex deep-drawing.

DC Aluminum Circle Plate: Best for deep-drawing and stamping. It has a more uniform grain size, which prevents "orange peel" textures or cracking when the metal is stretched deeply into shapes like high-walled pots.

Determine Dimensions and Temper

Thickness: Usually ranges from 0.3 mm to 10 mm. Cookware typically requires a thickness of 1.0 mm to 5.0 mm to ensure durability and good thermal conductivity.

Diameter: Standard size range is 100 mm to 1200 mm. Choose a diameter slightly larger than the “developed” surface area of the final product to allow for trimming.

Temper (hardness): O (annealed): The softest condition, ideal for deep drawing and complex spinning.

H12/H14: Partially hardened; suitable for flat signage or shallow forming that requires higher rigidity.
