Pure Aluminum Circle Manufacturing Capability

Our factory supplies aluminum circle discs in common grades including 1050, 1060, 1070, and 1100 aluminum. These grades are widely selected because of their high aluminum content, corrosion resistance, thermal conductivity, electrical conductivity, and good workability. The appropriate grade and temper depend on the final application, forming depth, surface treatment requirements, and mechanical performance needed by the buyer.

For deep drawn cookware and spun lighting components, soft temper aluminum circles are generally preferred because they provide better elongation and reduced cracking risk during severe deformation. For flat stamped parts, signs, reflectors, and structural components, H14 or other strain-hardened tempers may be selected to provide increased strength and shape stability.

We manufacture aluminum discs from controlled input coil, rather than sourcing random blanks from the market. This enables us to maintain process continuity from coil selection through slitting, blanking, packing, and shipment. Diameter, thickness, temper, surface condition, and packaging can be specified according to the customer's production requirements.

Technical Parameters for Mill Finish Aluminum Circles

The following table shows our standard production range for pure mill finish aluminum circles. Custom specifications can be evaluated according to material grade, tooling feasibility, order quantity, and application requirements.

Our tolerance capability is confirmed against the agreed order specification. For thinner aluminum circles, thickness consistency and flatness are particularly important. For heavier aluminum discs, diameter accuracy, edge quality, and deformation control during handling receive additional attention.

Available Aluminum Grades and Their Uses

1050 Aluminum Circle

1050 aluminum contains a minimum aluminum content of 99.5 percent. It is widely used for cookware, lamp shades, reflectors, traffic signs, chemical equipment components, and general spinning applications. Its excellent corrosion resistance and formability make it a practical choice for many aluminum disc applications.

Our 1050 Aluminum Circle can be supplied in O temper for deep drawing and spinning operations, or in harder tempers for stamped parts requiring improved rigidity. Customers commonly specify this grade for aluminum pots, pans, rice cooker inner components, and lighting housings.

1060 Aluminium Circle

1060 aluminium contains at least 99.6 percent aluminum and offers very good ductility, thermal conductivity, and electrical conductivity. It is frequently selected for deep drawn cookware, heat transfer parts, lighting products, capacitor shells, and decorative spun components.

Our 1060 Aluminium Circle is produced with close attention to grain structure, surface cleanliness, and edge finish. These factors are especially relevant when customers process the material through multiple drawing stages or require a consistent visual result after anodizing or polishing.

1070 and 1100 Aluminum Circles

1070 aluminum circle material provides high purity and good electrical performance, making it suitable for electronic, electrical, and specialized forming applications. 1100 aluminum circle material offers excellent corrosion resistance and workability, and is commonly used in cookware, signage, reflectors, chemical equipment, and decorative products.

Grade selection should not be based on aluminum content alone. Our technical team reviews the intended process, such as deep drawing, spinning, stamping, embossing, or anodizing, to recommend a suitable alloy and temper combination.

Surface Quality and Edge Control

A reliable mill finish aluminum circle must do more than meet nominal dimensions. Surface and edge conditions directly affect customer productivity, especially where the disc will be formed, polished, coated, or anodized.

Our manufacturing process is designed to control common issues that can interrupt downstream production. We inspect for scratches, oil marks, dents, edge burrs, laminations, stains, and other defects that may affect processing or finished appearance. Mill finish does not mean untreated or uncontrolled. It refers to the natural rolled surface condition, supplied without painted, anodized, or decorative coating.

For applications such as cookware and lighting, a stable mill finish surface provides a suitable base for polishing, non-stick coating, painting, anodizing, or mechanical finishing. For industrial uses, the clean surface supports efficient assembly, stamping, and welding preparation where applicable.

Forming Performance for Deep Drawing and Spinning

High performance aluminum circles are defined by how consistently they behave in the customer's forming operation. Deep drawing and spinning place significant demands on material ductility, grain uniformity, surface lubrication response, and edge integrity.

For deep drawn aluminum discs, we normally recommend O temper material. The annealed condition improves elongation and reduces the probability of cracking around the wall, flange, or corner radius of the formed part. The correct relationship between disc diameter, thickness, tooling geometry, drawing ratio, lubrication, and process sequence remains essential.

For spun aluminum components, such as lamp shades, cookware bodies, reflectors, and covers, the material should maintain uniform deformation around the circumference. Our aluminum circles are processed to support balanced material flow and minimize uneven edge behavior during spinning.

The following factors are reviewed during order confirmation:

• Final product shape and required drawing depth.

• Number of drawing or spinning stages.

• Required temper and mechanical properties.

• Surface treatment after forming.

• Required diameter and thickness tolerances.

• Flatness expectations before forming.

• Packaging method and handling conditions.

This production-focused approach helps ensure that the aluminum wafer supplied from our factory is aligned with the buyer's actual manufacturing process rather than only a basic material description.

Typical Applications of Aluminum Circle Discs

Pure mill finish aluminum circles are used across a broad range of industries because they combine low weight, corrosion resistance, good thermal performance, and favorable formability. Our customers process aluminum discs into finished components for both consumer and industrial markets.

Quality Control From Coil to Export Packaging

As a factory, we apply inspection procedures throughout production rather than relying only on final sampling. Input aluminum coil is checked for grade, thickness, surface condition, and temper requirements. During blanking or cutting, our operators monitor disc diameter, edge condition, stacking quality, and surface protection.

Final quality control can include thickness measurement at multiple locations, diameter inspection, visual surface inspection, flatness evaluation, weight verification, and packaging confirmation. Where specified, material certificates and inspection documentation can be provided with the shipment.

Export packaging is selected according to disc size, thickness, destination, and transportation method. Aluminum circles may be protected with interleaving paper, plastic film, moisture-resistant wrapping, steel straps, pallets, or wooden cases. Proper packaging reduces the possibility of scratches, oxidation staining, edge damage, and displacement during sea or land transportation.

Why Source Aluminum Circles Directly From Our Factory

Direct factory sourcing gives B2B buyers clearer control over specifications, production schedules, and quality requirements. We work with customers on thickness, diameter, alloy, temper, surface condition, and packaging before production begins. This helps reduce uncertainty in downstream processing and supports stable repeat supply.

Our production range from 0.4mm to 10mm allows us to serve both thin-gauge stamping applications and heavier-gauge industrial requirements. Whether the product is a 1050 aluminum circle for cookware, a 1060 aluminium circle for spinning, or a 1100 aluminum disc for general fabrication, our objective is to supply material that performs consistently in the next manufacturing stage.
