The secrets of high-end cookware often lie hidden in places invisible to the naked eye. In multi-layer composite cookware like pan and pots, aluminum circles act as a heat transfer hub, quickly and evenly distributing heat across the entire cooking surface.
Unlike ordinary aluminum sheets, aluminum circle for manufacturing pot and pans are precisely formulated. Mainly used are 1060 and 3003 aluminum alloys, achieving a perfect balance between purity and strength. These materials undergo a special process to achieve elongation of 30%-35% and a first-class grain size, endowing them with excellent deep-drawing and spinning properties. When the aluminum circles are processed into the base material of the cookware, a dense oxide film just 0.00001 mm thick forms on their surface. This natural barrier makes the product corrosion-resistant and rust-proof, while also preventing the rust staining common to iron pans. It's worth noting that this oxide film, while thin, is resilient. During daily cleaning, avoid vigorous abrasion with steel wool to avoid damaging the protective layer. While the oxide film regenerates naturally, proper maintenance can extend the life of the cookware.
The cookware industry places extremely stringent demands on the surface quality of aluminum circles. Any minor scratches or oil stains will be magnified during the subsequent deep-drawing process, resulting in surface defects in the finished pot. Haomei Aluminum utilizes a fully automated production line, with unmanned operations from coil unwinding to disc blanking. This process eliminates surface damage caused by manual contact, ensuring the aluminum discs have a smooth, scratch-free, clean and oil-free surface. Edge treatment is also crucial, advanced precision cutting technology ensures smooth, burr-free edges, preventing stress concentration and cracking during the subsequent deep-drawing process. Regarding corrosion resistance, high-end 3003 aluminum circles incorporate manganese alloy elements to create a "rust-proof aluminum" formula. The addition of manganese significantly enhances the material's rust and corrosion resistance, enabling the finished aluminum pots to withstand humid kitchen environments and the chemical reactions of various ingredients.
As a world-leading aluminum circles supplier, we offer unprecedented flexibility and customization. Diameters range from 100mm to 1200mm, and thicknesses can be customized to any specification from 0.4mm to 6.0mm. Material conditions are available upon request: a soft state (0) is suitable for deep-drawn cookware; semi-hard states such as H24 and H14 meet specific strength requirements.
In the production workshop of Haomei Aluminum, a fully automated production line produces one aluminum circle every two seconds. ISO 9001 and SGS product certification are certified, ensuring a reliable quality control system throughout the entire process. Control begins with the raw materials. The aluminum coils produced using a hot-rolling process achieve precision control of sheet tolerances exceeding national standards, providing a consistent material foundation for subsequent deep-drawing. Products are exported to overseas markets including Southeast Asia and Africa.
The modern production base is equipped with cutting-edge equipment:
- A wide-width press line with a nominal pressure of 160 tons can process coils up to 1.6 meters wide.
- A modular die system reduces format changeover time to less than 15 minutes.
- A high-speed stamping capacity of 55 sheets per minute.
- Export packaging is equally professional and rigorous. Built-in moisture-proofing agents and impact-resistant wooden pallets or crates ensure the product's surface remains pristine after transoceanic transportation.
With the global high-end cookware market growing at an annual rate of 5.8%, demand for high-quality cookware is surging among Southeast Asia's emerging middle class. Composite cookware featuring customized aluminum circles commands a premium of 2-3 times that of standard products in overseas markets. Their core selling point is the uniform heating and energy-saving properties provided by the aluminum discs. We are ready to provide you with free sample testing, customized technical solutions, export packaging, and integrated logistics services—helping your cookware products achieve both global recognition and profitability.
