1070 Aluminum Circle for Non-Stick Cookware

Title

In today's modern kitchen, a lightweight, smooth, and non-stick pan has become essential for enhancing cooking comfort and efficiency. While most people focus on the surface coating of a non-stick pan, the true performance actually depends on its core material - the metal base. The choice of substrate determines heat distribution, durability, and the overall quality of cookware. Among the many options, 1070 cookware aluminum circle stands out for its purity, processability, and performance - bringing innovation and efficiency to your cookware manufacturing line or kitchen experience.

Understanding 1070 Aluminum Circle

The 1070 aluminum circle belongs to the 1000 series of pure aluminum products, with an aluminum content of over 99.7%. This high-purity industrial aluminum offers excellent chemical stability, good formability, and a bright surface finish. It is widely used in stamping, spinning, and deep drawing processes to produce cookware, lamp reflectors, road signs, and packaging lids.

Key Features of 1070 Aluminum Circle

Uniform Heat Distribution
The high aluminum purity enables rapid and even heat transfer, preventing localized overheating and improving cooking efficiency.
Excellent Formability
Performs stably during spinning, stretching, and deep drawing - ideal for producing cookware of various sizes and shapes.
Lightweight Design
With a density only one-third that of steel, 1070 aluminum significantly reduces overall pan weight, making it easier to handle.
Corrosion Resistance & Eco-Friendly
The surface can be anodized to form a dense protective oxide layer that resists corrosion. It is non-toxic, recyclable, and meets food contact safety standards.

Surface Treatment & Coating Compatibility

1070 aluminum circles feature a clean, bright surface and stable chemical composition, making them highly adaptable for various surface treatments such as anodizing, polishing, sandblasting, brushing, and spraying.
They can be coated with PTFE, ceramic, or granite coatings, ensuring strong adhesion, wear resistance, and long-lasting non-stick performance.
Thanks to their uniform heat conduction, coatings are less likely to blister or peel under high temperatures - keeping cookware shiny, easy to clean, and durable through long-term use.

1070 vs. 3003 Aluminum Circle for Non-Stick Pans

Compared with 3003 aluminum circle, the 1070 aluminum circle has higher purity (≥99.7%), offering superior heat conductivity and formability, as well as a lighter overall weight.
The 3003 alloy contains a small amount of manganese, providing higher strength and slightly better corrosion resistance, making it more suitable for heavy-duty cookware.
In summary, 1070 aluminum is ideal for lightweight, fast-heating non-stick cookware, while 3003 aluminum fits premium, durability-focused cookware lines.
