Aluminum Circle for Cookware
Aluminum Circle for Cookware is a key raw material in cookware manufacturing, made from high-purity aluminum or aluminum alloys (e.g., 1050, 1060, 3003, 3004) through hot or cold rolling processes. Its lightweight, uniform heat conductivity, corrosion resistance, and ease of processing make it ideal for pots, pressure cookers, baking trays, and other kitchenware.

Overview
Aluminum Circle for Cookware is a specialized aluminum product tailored for manufacturing cookware. It is produced by blanking high-quality aluminum coils into circular blanks with precise diameter and thickness, featuring excellent thermal conductivity, formability, and food safety compliance. As the core material of cookware, it can be deep-drawn, stamped, and formed into various cookware shapes (such as frying pans, saucepans, pots, and woks). Compared to materials like stainless steel or cast iron, it offers advantages of fast and uniform heat conduction, lightweight, and easy processing, making it the preferred choice for cookware manufacturers worldwide.
Specification
Alloy：1100，1050，1060，3003，5052，3104，3005，3105，5005，5052

Feature
1.High Thermal Conductivity: Aluminum’s thermal conductivity (237W/(m·K)) is 3× that of iron, it ensures fast and uniform heat distribution across the cookware surface, avoiding local overheating and burning of food.
2.Superior Formability: High ductility allows deep drawing into complex shapes (such as pots with curved bottoms or high sides) without cracking. It can withstand repeated stamping processes, meeting the production needs of various cookware designs.
3.Lightweight: Density is 1/3 of stainless steel, easing handling and reducing shipping costs.
4.Food Safety & Corrosion Resistance: Complies with global food safety standards, and the natural oxide film or anodized layer prevents aluminum oxidation and corrosion from acidic/alkaline food (such as tomatoes, vinegar). No harmful substances are released even during long-term use.
5.Cost-Effective & Efficient Production: Lower raw material and processing costs compared to copper or stainless steel. The blanking and forming processes are simple, with high production efficiency, reducing cookware manufacturing costs.
Application
Aluminum circles are mainly used for woks, frying pans, soup pots, pressure cookers, rice cooker liners, baking trays, pizza pans, bread molds, etc.
