Title

As an aluminum circle manufacturer, we produce aluminum circles and aluminum discs for cookware, lighting, traffic signs, electronics, ventilation components, and deep-drawn industrial parts. Our production is organized around controlled raw material selection, stable rolling performance, accurate blanking, inspection, and export packaging.

For international buyers, ASTM compliance is not only a material reference. It is part of a broader supply requirement that includes alloy chemistry, temper, dimensional tolerance, surface condition, traceability, documentation, and shipment protection. We manufacture aluminum circles according to customer drawings and purchase specifications, with material properties referenced to applicable ASTM requirements, including ASTM B209 where relevant for aluminum sheet and plate source material.

Our factory supplies aluminum circle products to customers in overseas markets with different forming methods, quality expectations, and logistics conditions. Whether the requirement is for a standard cookware blank or a custom large-diameter aluminum disc, we confirm the technical specification before production and maintain process controls throughout the order.

ASTM Compliance in Aluminum Circle Manufacturing

An ASTM-compliant aluminum circle begins with suitable aluminum coil or sheet. We select source material based on the requested alloy, temper, thickness, mechanical properties, and end-use forming process. For customers requiring ASTM-referenced material, we can provide mill test certificates and inspection records in accordance with the agreed order requirements.

ASTM B209 is commonly referenced for aluminum and aluminum-alloy sheet and plate. Since aluminum circles are cut or blanked from coil and sheet, compliance is evaluated through the source material specification and the agreed finished-product criteria. We work with buyers to define the applicable standard, alloy designation, temper, gauge, dimensions, and acceptance conditions before confirming production.

Our quality team verifies the following items as applicable:

• Alloy designation and chemical composition.

• Temper condition, such as O, H12, H14, H22, or H24.

• Thickness, diameter, and specified dimensional tolerances.

• Surface quality, including oil level, scratches, edge condition, and oxidation marks.

• Flatness and forming suitability.

• Mechanical properties when required by the purchase specification.

• Batch identification and export documentation.

This approach helps industrial buyers receive aluminum discs that are appropriate for their equipment, tooling, and downstream manufacturing process.

Aluminum Circle Alloys and Tempers We Manufacture

We manufacture primarily 1000 series aluminum circles because these grades offer high aluminum purity, good corrosion resistance, thermal conductivity, and excellent workability. They are widely selected for deep drawing, spinning, stamping, anodizing, and general fabrication.

Common options include 1050, 1060, 1070, and 1100 aluminum circle materials. The selection depends on the required forming depth, finished product appearance, conductivity, strength, and local specification requirements. Our 1000 Series Aluminum circle range is designed for processors that need consistent material behavior from batch to batch.

For deep-drawn cookware and pressure cooker components, annealed O temper is frequently selected because it provides high elongation and low forming resistance. H14 and H24 tempers are commonly used when moderate strength, shape retention, or less severe forming is required. We can also discuss intermediate tempers based on the buyer's production process.

For customers seeking a versatile grade for cookware blanks and deep drawing, our 1060 Aluminium Circle can be supplied in customized diameters, thicknesses, and temper conditions.

Technical Parameters for Aluminum Discs

We manufacture standard and custom aluminum circle sizes. The final production range depends on alloy, thickness, temper, diameter, edge requirement, and blanking method. Large-diameter circles, thick aluminum discs, and special dimensional tolerances are reviewed individually before order confirmation.

The values above are general manufacturing capabilities rather than a substitute for a confirmed technical agreement. For export projects, we recommend that buyers provide the required alloy, temper, diameter, thickness, intended application, and tolerance limits during inquiry. This allows our engineering and quality teams to recommend a suitable aluminum circle specification.

Controlled Production for Forming Performance

The manufacturing quality of an aluminum disc is strongly connected to its behavior during drawing, spinning, stamping, and anodizing. A circle with acceptable nominal dimensions may still cause downstream problems if the grain structure, hardness consistency, surface cleanliness, or edge quality is not properly controlled.

Our process starts with verified aluminum coil or sheet. We then conduct slitting or sheet preparation, circle blanking, dimensional inspection, surface checking, and packing according to the agreed requirements. When annealed O temper aluminum circles are required, we control the annealing process to support stable forming performance.

For cookware aluminum discs, particular attention is given to deep-drawing quality. We inspect for issues that may affect production, including burrs, edge cracks, heavy scratches, embedded particles, uneven oil, and visible rolling marks. The target is to provide a clean, consistent blank that can enter the customer's forming line with minimal preparation.

Applications for Export Aluminum Circles

Our aluminum circles are used by manufacturers rather than resellers in a wide range of finished products. Material selection is matched to the forming method and performance requirements of each application.

Cookware and Kitchenware

Aluminum circles are widely used as blanks for frying pans, saucepans, stockpots, pressure cookers, non-stick cookware, baking tools, and kitchen utensils. O temper 1050 and 1060 aluminum circles are common choices for deep drawing and spinning. Thickness, surface quality, and flatness are important for stable forming and later coating operations.

Lighting and Reflective Components

Aluminum discs can be formed into lampshades, reflector housings, LED lighting components, and decorative lighting parts. Depending on the final process, customers may require controlled surface quality, reflective finishing compatibility, or a specific temper for spinning.

Traffic Signs and Industrial Identification

Aluminum circle and disc materials are used for circular traffic signs, safety markers, identification plates, and industrial labeling. These applications may require flatness, corrosion resistance, and surface preparation suitable for painting, printing, or reflective film lamination.

Electrical and General Fabrication

High-purity aluminum circles can also be used in electrical components, heat-related assemblies, capacitors, ventilation covers, and fabricated metal parts. We evaluate each order according to the required conductivity, forming behavior, and surface condition.

Quality Inspection and Documentation

Our factory applies inspection procedures at key manufacturing stages. Incoming material verification, in-process checks, and final inspection are used to reduce variation before the goods are released for export.

Final inspection may include thickness measurement, diameter measurement, visual surface examination, edge inspection, flatness checking, quantity verification, and packaging review. Sampling plans and acceptance criteria can be aligned with the customer's purchase order or agreed quality plan.

For projects with documentation requirements, we can prepare relevant commercial and quality documents, including:

• Commercial invoice and packing list.

• Certificate of origin when applicable.

• Mill test certificate for the source material or supplied batch, as agreed.

• Product inspection report.

• Shipping marks and pallet identification labels.

• Third-party inspection coordination when requested.

Clear documentation supports customs clearance, receiving inspection, and traceability at the buyer's facility.

Export Packaging for Aluminum Circle Shipments

Aluminum circle packaging must protect the material from moisture, scratches, deformation, and movement during container transport. We select packaging according to circle diameter, thickness, quantity per package, destination, and handling method at the receiving warehouse.

Small and medium aluminum discs are generally packed in strong export cartons or wooden cases with moisture-resistant inner protection. Large aluminum circles may be stacked with interleaving materials and secured on fumigated wooden pallets. Outer strapping and protective corner materials are applied where needed to improve shipment stability.

Each package can be marked with the order number, alloy, temper, dimensions, quantity, gross weight, net weight, and destination details. This labeling helps customers identify material efficiently after container unloading.

Worldwide Supply From Our Manufacturing Facility

As a factory-based aluminum circle exporter, we support buyers with specification confirmation, sample evaluation, mass production, quality inspection, and export packing. We understand that international customers need more than a quoted price. They need dependable material consistency, accurate documentation, protected delivery, and responsive technical communication.

Before production, our team reviews the end use of the aluminum circle, the required ASTM reference, the requested dimensions, and the forming process. This preparation helps reduce uncertainty and ensures that the supplied aluminum discs are suitable for the buyer's manufacturing conditions.

For ASTM-compliant aluminum circles exported worldwide, we provide a practical manufacturing solution based on controlled raw materials, disciplined production, inspection records, and secure export packaging.
