Due to its excellent thermal conductivity and lightweight characteristics, aluminum circle is widely used in the production of various cookware, such as frying pans, pressure cookers, milk pots, and more.
The temper of the Aluminium Circle Sheet for Pot is typically O-temper, which is an annealed state that provides good elongation and plasticity, making it suitable for deep drawing processes. To ensure that the final product is not prone to cracking or deformation during processing, Haomei Aluminum mainly uses hot-rolled base material, with strict process control to ensure good and uniform grain structure, significantly enhancing its adaptability to deep drawing and spinning.
Specifications of Aluminum Circle for Cookware
Aluminum circles for cookware mainly use 1060 and 3003 aluminum alloys, which have excellent ductility and formability, making them suitable for deep drawing and spinning processes. They are commonly used in the production of various kitchen cookware, such as pots, frying pans, pressure cookers, and more. Depending on different processing needs, aluminum circles can be produced through two methods: DC (hot-rolled) and CC (cold-rolled).
Material of Aluminium Circle Sheet for Pot
- 1060 aluminum alloy: Contains up to 99.6% aluminum, with good ductility, thermal conductivity, and corrosion resistance. It is suitable for deep drawing and spinning processes that require high processing performance.
- 3003 aluminum alloy: Contains a small amount of manganese, which enhances the strength and corrosion resistance of the alloy while maintaining good formability. The 3003 alloy is more suitable for cookware that requires higher strength, such as pressure cookers.
Specifications of Aluminium Circle Sheet for Pot
- Thickness range: 0.4 to 5.0mm.
- Diameter range: Customized according to customer requirements, with common diameters ranging from 100mm to 1200mm.
- Temper: Usually supplied in O-temper (annealed state) to ensure good flexibility and formability, facilitating subsequent deep drawing and spinning processes.
As an important raw material in the production of cookware, the selection of aluminum circles and the processing technology are critical to the quality and performance of the products. By using high-quality 1060 and 3003 aluminum alloys and precise DC and CC process control, the final products can have excellent ductility, durability, and thermal conductivity, meeting the production needs of various kitchenware.
Advantages of Haomei Aluminium Circle Sheet for Pot
Haomei Aluminum can provide aluminum circles in various diameters according to customer requirements. For cookware aluminum circles used for stamping and drawing, they have high surface smoothness, no scratches, and high elongation. The cookware aluminum circles have high thermal conductivity, enabling the cookware made from them to quickly transfer heat from the heat source to the food, providing optimal conditions for cooking.
Features of Aluminum Circles for Cookware
- 1. Excellent ductility: Aluminum circles for cookware have excellent ductility, suitable for deep drawing processes, and can be processed into various shapes, such as frying pans, sauté pans, milk pots, pressure cookers, and more. This feature ensures that the product remains intact and aesthetically pleasing during the manufacturing process, without cracking or deformation.
- 2. Outstanding thermal conductivity: Aluminum has excellent thermal conductivity, and the even heating properties of aluminum circles help cookware transfer heat quickly during cooking, reducing cooking time and ensuring that the food is heated evenly, improving cooking efficiency.
- 3. Corrosion resistance: Aluminum has inherent oxidation resistance, and with special surface treatments, aluminum circles for cookware can resist corrosion from common kitchen acids, alkalis, and moisture, extending the life of the cookware.
- 4. Lightweight: Aluminum circles are lightweight, and the cookware made from them is easy to handle, carry, and use. Compared to traditional iron or stainless steel cookware, aluminum cookware offers a more convenient advantage.
- 5. Environmentally friendly and recyclable: Aluminum is a fully recyclable and environmentally friendly material. Products made from aluminum circles for cookware not only have a long service life but can also be recycled after disposal, reducing resource waste and environmental burden.
Aluminum Circle for Pot Bottom
Some high-end stainless steel pots have at least three layers at the bottom, two of which are steel, with aluminum in the middle as a heat-conducting material. We know that aluminum has good thermal conductivity, but it is not magnetic, so it doesn't interact with induction, while steel is magnetic, making these pots usable on induction cookers.
Aluminum Circle for Rice Cooker
The material of the inner pot of a rice cooker significantly affects its performance and durability. Choosing the right material is key to ensuring its durability and effectiveness. The quality of a rice cooker inner pot mainly depends on three aspects: the design of the inner pot, the materials used, and the choice of non-stick coating.
Currently, inner pots for rice cookers with a capacity of 3L and 4L generally use aluminum circles with a thickness of 1.5 to 1.6mm, while 5L and 6L capacity rice cookers use aluminum circles with a thickness of 1.8 to 2.2mm. These aluminum inner pots have good thermal conductivity and durability, making them suitable for everyday cooking needs.
Popular Aluminum Circles for Cookware
- 1. Used in the inner pots of small appliances (rice cookers, electric pressure cookers, bread machines, soy milk machines, juicers, air fryers, coffee pots, kettles);
- 2. Cooking utensils (non-stick pans, frying pans, steamers, milk pots, pressure cookers, enamel pots);
- 3. Various aluminum containers, aluminum pots, aluminum trays, aluminum lids, aluminum boxes, tea cans, aluminum barrels, aluminum cans, medicine cans;

- 5. Anodized kitchenware, anodized cookware, anodized tableware;
- 6. Hard-anodized kitchenware, hard-anodized cookware, hard-anodized tableware;
- 7. Outdoor kitchenware, outdoor cookware, outdoor tableware, outdoor pot sets, outdoor cookware sets.
Processing Technology for Aluminum Circles for Cookware
Aluminum circles for cookware typically go through a strict production process, including smelting, hot rolling, cold rolling, stamping, and surface treatment. To ensure their suitability for different cookware applications, the thickness, diameter, and surface treatment of the circles can be customized according to customer needs. For example, the surface can undergo oxidation treatment to improve corrosion resistance or polishing to enhance appearance.
Production Process
- DC Aluminium Circle Sheet for Pot: Produced by hot rolling, the material has a more uniform and refined grain structure with excellent surface quality, suitable for deep drawing processes that require high strength and ductility, such as producing high-end cookware and complex-shaped kitchen utensils.
- CC Aluminium Circle Sheet for Pot: Produced by cold rolling, with a smooth and flat surface, suitable for relatively simple spinning processes. It is usually used in kitchen utensils with lower requirements.
Production Process Flow: Aluminum circles are a semi-finished product made by continuously stamping from large rolls of aluminum sheets. After rolling and annealing processes, the aluminum coil reaches the required thickness and properties, and then automatic stamping equipment is used to cut it into circles. The aluminum circles produced by the DC process have a more uniform grain structure, making them suitable for deep drawing or spinning processes that require high ductility and strength.
