Aluminum Circles for Rice Cooker Inner Pot
Aluminum circles are widely used in the production of rice cooker inner pots, aluminum pans, and various kitchen utensils such as frying pans, saucepans, and pizza pans.
The aluminum circles used for rice cooker inner pots feature excellent deep drawing performance, high tensile strength, good elongation, perfect surface quality, and stable performance. They are suitable for anodizing and hard anodizing surface treatments.
Compared with stainless steel or iron materials, cookware aluminum circles provide more uniform heat distribution, allowing rice to cook more evenly and improving texture and flavor. As a result, aluminum has become the mainstream material for modern rice cooker inner pots.
Main Aluminum Materials for Rice Cooker Inner Pots
Aluminum circles for rice cookers are commonly made from 1050, 1060, 3003, and 5052 alloys, among which 3003 aluminum circle is the most widely used in the market.
The Mn (manganese) content in 3003 aluminum enhances corrosion resistance and hardness, while maintaining excellent thermal conductivity - ideal for non-stick coating or anodizing processes.
Depending on specific performance requirements, rice cooker manufacturers choose different alloy types:
| Alloy Grade | Main Features | Typical Applications | Recommended Temper |
| 1050 / 1060 | High purity, excellent thermal conductivity, easy to spin-form | Household and commercial rice cookers | O, H0 |
| 3003 | Manganese alloy, strong corrosion resistance, suitable for anodizing | Mid- to high-end rice cooker inner pots | H14, H24 |
| 5052 | High strength, wear resistance, excellent oxidation resistance | IH induction rice cookers | H32, H34 |

Why Choose Aluminum Circles as Rice Cooker Inner Pot Material?
1. Excellent Thermal Conductivity
Aluminum has a very high thermal conductivity, quickly and evenly transferring heat from the bottom heating plate throughout the entire pot for uniform rice cooking.
2. Lightweight Structure
With a density of only 2.71 g/cm³, aluminum inner pots are about 40% lighter than traditional steel ones, making them easier to handle and more energy efficient.
3. Easy Forming and Versatile Shaping
Aluminum circles have great ductility, suitable for deep drawing, spinning, and stretching processes to create various inner pot shapes (round-bottom, flat-bottom, honeycomb, etc.).
4. Compatible with Multiple Coating Technologies
Aluminum surfaces can be treated with anodized layers, non-stick coatings, or ceramic coatings, enhancing durability, corrosion resistance, and aesthetics.
5. Cost Efficiency
Aluminum offers significant cost advantages compared with stainless steel or copper.
6. Eco-Friendly and Recyclable
Aluminum is 100% recyclable and free from harmful substances, compliant with EU RoHS and REACH environmental standards.
