Food Grade Non-Stick Cookware Aluminum Circle

Core Advantages

1. Food Grade Material for Kitchenware Production

Made from food contact safe aluminum substrate, this aluminum circle is suitable for cookware raw material applications, helping meet basic hygiene requirements for kitchen utensil manufacturing.

2. Excellent Deep Drawing Performance

The aluminum circle shows good ductility and forming stability. It can be deep drawn into various pan shapes without cracking, wrinkling or springback deformation, which is critical for high-yield cookware production.

3. Smooth Surface for Non-Stick Coating

The surface is clean, uniform and low in defects. It provides a good base for subsequent degreasing, surface treatment, primer spraying and non-stick coating application.

4. Pre-Coated Option Available

We can supply prepainted aluminum circles with a protective primer layer. This option can help cookware manufacturers save processing steps, reduce on-site coating operations and improve production efficiency.

5. Stable Thickness Tolerance

Controlled thickness tolerance helps ensure consistent forming performance during pan production. It reduces material waste and helps maintain uniform pan wall thickness after deep drawing.

6. Good Thermal Conductivity

Aluminum material provides efficient and even heat transfer. After being formed into cookware, it can support stable heating performance for frying, boiling, stir-frying and other cooking applications.

7. Customizable Size Range

We offer aluminum circles in various diameters and thicknesses to match different cookware molds, pan sizes and production requirements.

8. Suitable for Mass Production

The product is designed for industrial cookware manufacturing. It can be used for automatic stamping lines, deep drawing presses, spinning machines and continuous non-stick coating lines.

Detailed Product Features

Material Selection

The aluminum circle can be produced from 1050 or 3003 aluminum alloy, depending on the customer’s cookware design, thickness requirement, forming process and end-use application.

• 1050 Aluminum Circle: High purity aluminum, good thermal conductivity, lightweight and suitable for thin-gauge non-stick pans.

• 3003 Aluminum Circle: Anti-rust aluminum alloy, better strength and corrosion resistance, suitable for thicker pans, woks and durable cookware.

Surface Quality

The aluminum circle surface is processed to minimize oil stains, oxidation spots, scratches, dents and other defects. A clean and flat surface is important for the subsequent non-stick coating process. Poor surface condition may cause coating bubbling, peeling, uneven adhesion and appearance rejection.

Forming Performance

One of the most important characteristics of cookware aluminum circle is deep drawability. During pan production, the aluminum disc is stamped and stretched into a three-dimensional pan shape. The material must be soft enough to deform, but stable enough to avoid cracking and excessive thinning.

Our aluminum circles are controlled in terms of material temper, grain structure and surface quality to support consistent forming performance.

Prepainted Aluminum Circle Option

For customers who want to simplify their production process, we can provide pre-coated aluminum circles. The pre-coating is usually applied as a primer layer before deep drawing or before non-stick coating.

This option can:

• Improve coating adhesion

• Reduce factory painting steps

• Lower surface preparation workload

• Enhance production line efficiency

• Provide more uniform surface coverage

Applications

1. Non-Stick Frying Pan

Used as the base material for non-stick frying pans, flat pans and induction pans.

2. Wok Production

Suitable for deep drawing and spinning into woks, stir-fry pans and large cooking pans.

3. Saucepan and Milk Pan

Can be formed into saucepans, milk pans, soup pots and small kitchen utensils.

4. Commercial Cookware

Suitable for catering equipment, restaurant kitchenware and commercial cooking pans.

5. Cookware OEM Manufacturing

Widely used by kitchenware factories for OEM non-stick pan production.

6. Non-Stick Coating Base

Provides a stable aluminum base for subsequent PTFE, ceramic or non-stick coating systems.
