As the sales manager at Haomei Aluminum, specializing in the export of aluminum circles for cookware, I am keenly aware of the stringent requirements of global cookware manufacturers for raw materials. 1100 aluminum circles, representing industrial pure aluminum (aluminum content ≥99.0%), have become the preferred base material for global cookware brands due to their superior formability and food safety. For the past 18 years, we have provided stable supply to customers in over 50 countries across North America, Europe, and the Middle East, with cumulative exports exceeding 100,000 tons. Each batch embodies Haomei's commitment to quality.

Our 1100 aluminum circles utilize a hot-rolled + cold-rolled composite process, covering diameters from 80-800mm and thicknesses precisely controlled within 0.5-4.0mm (tolerance ±0.02mm), perfectly matching the stretching and forming requirements of various cookware such as frying pans, woks, and pressure cookers. Available in two states: O (soft) and H14 (semi-hard). The O state has an elongation of ≥35%, suitable for deep-drawn cookware; the H14 state has a hardness of HB23-32, balancing strength and machinability, suitable for cookware bases requiring rigidity. Each round piece undergoes precision deburring, eliminating sharp edges and effectively reducing mold wear and worker handling risks during production.

Facing stringent standards such as the EU LFGB and the US FDA, we control safety from the source. We use 99.7% high-purity aluminum ingots as raw materials, strictly limiting heavy metal content: lead and cadmium migration are both below 0.005mg/kg, far exceeding the EU EN602 standard limit of 0.01mg/kg. The entire process is ISO9001 and ISO22000 dual certified, and each batch provides a Material Certificate (MTC) and third-party testing report, ensuring zero obstacles for customers during customs clearance and market access. Last year, a 2000-ton order customized for a German client, tested by TÜV Rheinland, showed aluminum migration at only 1/8 of the standard limit, helping the client successfully enter the high-end cookware market.

Performance advantages of 1100 aluminum circle for cookware including:
- Thermal conductivity:
1100 aluminum has a thermal conductivity of 220 W/(m·K), 5 times higher than ordinary steel, ensuring even heating of cookware and reducing localized scorching. This is one of the core advantages reported by our American clients.
- Forming capability:
With an elongation rate of up to 38%, complex cookware can be formed in a single stretching process, with a scrap rate controlled below 0.3%, reducing material waste costs for clients by more than 15%.
- Corrosion resistance and coating adhesion:
The surface undergoes chemical cleaning and passivation treatment to form a uniform oxide film, enhancing salt spray corrosion resistance (neutral salt spray test ≥48 hours) and improving non-stick coating adhesion by 20%, extending the lifespan of the cookware.

Haomei's differentiated advantages:
- Small Batch Customization:
Supports orders starting from 5 tons, with 7-day rapid sampling to meet customers' new product development and market testing needs—a rarity in the industry.
- Transparent USD Pricing:
FOB Shanghai/Qingdao ports, providing a transparent pricing model based on real-time LME aluminum prices + processing fees, with monthly price index updates to help customers lock in costs.
- Packaging and Logistics:
Utilizes export-specific moisture-proof packaging (PE film + cardboard + wooden pallets), combined with rust-proof paper, ensuring no oxidation during long-distance sea transport. Long-term partnerships with shipping companies such as Maersk and MSC ensure full container orders reach major European ports within 25 days, and air freight orders are delivered globally within 72 hours.

In the cookware manufacturing industry, the quality of raw materials directly determines the value of the final product. Haomei 1100 aluminum circles are more than just a metal substrate; they are a reliable partner for customers expanding into global markets. We helped a Turkish customer solve a tensile cracking problem by adjusting the alloy composition and annealing process, increasing the product qualification rate from 85% to 99.8%, helping them become the second-largest cookware exporter in the region.

Choosing Haomei means more than just high-quality aluminum circles; it means access to 25 years of export experience, technical support, and supply chain security. Samples and the latest USD quotes are available upon request. We look forward to working with you to expand the global cookware market and jointly write a story of quality manufacturing.
