0.8mm Non-Stick Coated Aluminium Disc, Deep Drawing Grade for Cookware Manufacturing

0.80mm aluminum circle is a round aluminum blank for manufacturing pots, pans and other formed cookware. Available alloy options include 1050, 1060, 1100 and 3003, allowing cookware manufacturers to select the required balance of formability, strength and downstream surface finishing.

The circles can be processed by deep drawing, spinning, stamping and other compatible forming methods. The featured thickness is 0.80mm, while diameter, temper and other dimensions can be selected according to the finished pot geometry and forming process.

For non-stick cookware production, the aluminum circle may be used as the substrate for subsequent surface preparation and coating. Where a functional non-stick coating is required on the aluminum disc before delivery, the coating chemistry, coating side, forming sequence, curing conditions and applicable food-contact requirements should be confirmed before production.

Choosing 1050, 1060, 1100 or 3003 Aluminum Circle

1050 Aluminum Circle

1050 is a high-purity aluminum grade with good ductility and forming characteristics. It can be considered for cookware requiring relatively easy drawing or spinning where high structural strength is not the primary requirement.

1060 Aluminum Circle

1060 contains a high proportion of aluminum and provides useful ductility and thermal conductivity for compatible cookware forming processes.

1100 Aluminum Circle

1100 aluminum combines good formability with established use in fabricated cookware and general formed aluminum products. Final temper should be matched to the drawing depth and manufacturing route.

3003 Aluminum Circle

3003 is an aluminum-manganese alloy offering greater strength than typical 1xxx-series aluminum while maintaining useful formability. It can be evaluated for cookware requiring additional stiffness or more demanding formed construction.

Temper Selection for Cookware Forming

Temper is one of the most important factors in determining whether an aluminum circle can be formed into the required cookware shape without excessive cracking, wrinkling or springback.

O Temper

O temper provides a softer material condition and can be considered where greater forming allowance is required for deeper drawing or more severe deformation.

H12 and H14

H12 and H14 conditions provide increased work hardening compared with O temper. They can be selected for cookware designs where the forming geometry and tooling are compatible with the reduced ductility.

Do not select temper only from the finished product name. Finished depth, diameter, corner radius, number of drawing stages, tooling and lubrication should be considered together.

Why 0.80mm Thickness Is Important

The 0.80mm gauge provides a lightweight starting material for compatible pot and pan designs. Its suitability depends on the finished vessel diameter, wall height, base geometry, forming route and required rigidity.

A deeper, larger or more highly loaded cookware body may require a different starting gauge. Buyers should specify the finished cookware dimensions rather than selecting the aluminum circle solely by nominal thickness.

Deep Drawing and Spinning Performance

Deep Drawing

Deep drawing transforms the flat aluminum circle into a hollow cookware body using dies and controlled metal flow. Material consistency, temper, tooling clearance and lubrication all influence the final result.

Spinning

Metal spinning gradually forms the aluminum blank over a mandrel. The process can be suitable for round pots, pans, covers and other rotationally symmetrical cookware components.

Drawing Depth

The maximum practical drawing depth cannot be determined from alloy name alone. Circle diameter, blank thickness, temper, draw ratio, tooling, lubrication and number of forming stages should be evaluated together.

Earing and Edge Control

For demanding deep-drawing production, buyers can define requirements for edge condition, dimensional tolerance and earing behavior where these factors affect trimming loss or automated forming efficiency.

Non-Stick Coating and Surface Processing

A non-stick cookware system includes more than the aluminum substrate. Surface preparation, primer, functional coating, cure schedule and final coating thickness can all affect adhesion, forming behavior and finished cooking performance.

Form First, Then Coat

Where the cookware body is formed before application of the non-stick system, the aluminum circle should be selected primarily for forming performance and compatibility with the subsequent surface preparation and coating process.

Pre-Coated Circle

If the aluminum circle is coated before forming, the coating system must be suitable for the intended deformation. Deep drawing can place significant strain on the coating, so coating flexibility and adhesion should be validated for the actual forming geometry.

Coating Specification

Where a functional non-stick coating is required, specify the coating system, coated side, color, dry-film requirement, cure conditions, intended cookware use and any contractual performance tests.

Food-Contact Requirements

An aluminum circle intended for cookware should not automatically be described as compliant with every food-contact regulation. Compliance depends on the final cookware construction, surface treatment, coating system, intended food type, temperature, duration of contact and destination market.

Where food-contact documentation or migration testing is required, provide the applicable market and test requirements before production so the material and coating documentation can be reviewed against the intended finished product.

Why Aluminum Circles Are Used for Pots and Pans

Low Weight

Aluminum has relatively low density, helping cookware manufacturers produce lightweight pots and pans compared with many heavier metallic constructions of similar geometry.

Thermal Conductivity

Aluminum transfers heat efficiently, which is useful for cookware requiring rapid heating and distribution of heat through the vessel body.

Formability

Suitable aluminum alloys and tempers can be deep drawn, spun, stamped or otherwise formed into round cookware bodies and lids.

Surface Finishing Options

Depending on the alloy and manufacturing route, aluminum cookware can receive subsequent surface treatments such as coating, anodizing or other approved finishing processes.

Surface Quality Requirements

Flatness and Disc Geometry

Stable circle geometry helps maintain repeatability during feeding, centering and forming. Diameter and thickness tolerances should be agreed where automated cookware production requires tighter dimensional control.

Edge Condition

Edges should be inspected for excessive burrs, damage or deformation that could affect forming operations or operator handling.

Surface Defects

Where the surface remains visible or receives a decorative or functional coating, acceptable limits for scratches, dents, stains, oxide marks and other surface defects should be defined according to the finished cookware requirement.

Production and Aluminum Circle Processing

Aluminum circles are punched or cut from aluminum sheet or coil and can then be processed to the required material condition for the intended forming route. Dimensional inspection and surface inspection should be completed before downstream cookware fabrication.

Roll-Coated vs. Post-Form Coating

Continuous roller coating can provide controlled and repeatable application on flat aluminum stock where the selected coating is suitable for coil or sheet processing.

For cookware that requires significant deep drawing, however, the coating sequence should be selected carefully. A coating applied before forming must tolerate the actual strain imposed during drawing or spinning. Where this has not been qualified, forming the aluminum first and applying the functional cookware coating afterward may be the more appropriate manufacturing route.
