Anodized Brushed Mill Finish 1050 1060 3003 Pure 99.6% Aluminum Circle 0.3-6mm Corrosion Resistant Disc for Cookware

Our aluminum circle is manufactured from high-purity aluminum with purity levels of 99.60%, 99.70% and up to 99.90%, covering 1000, 3000 and 5000 series alloys including 1050, 1060 and 3003. Low impurity content (≤0.4%) ensures consistent material properties, superior deep drawing formability and excellent surface quality. This high-purity aluminium disc material delivers outstanding corrosion resistance, ductility and thermal conductivity.

Available in three surface finish options—mill finish, brushed and anodized—our aluminum circles meet diverse cookware production requirements. The anodized surface provides an ideal substrate for PTFE non-stick coating and ceramic coating adhesion, while the brushed finish delivers a premium satin appearance for high-end kitchenware. Mill finish offers a cost-effective base ready for further processing.

Produced using advanced DC hot rolling and CC cold rolling processes, our aluminum circles achieve a flatness tolerance of ±0.02mm and thickness tolerance of ±0.05mm. This precision engineering minimizes material waste during deep drawing and stamping, improves forming consistency and reduces rejection rates in automated production lines. The material can be spun, stamped and pressed deeply without cracking.

Cookware & Kitchenware: The most popular application for aluminum circles. They are widely deep drawn into non-stick frying pans, saucepans, stockpots and pressure cookers. The anodized surface finish option provides excellent adhesion for PTFE and ceramic non-stick coatings, making them the preferred aluminium disc material for premium cookware brands worldwide. Mill finish and brushed options are commonly used for bakeware, roasting trays and kitchen utensils.

Automotive Components: Thanks to superior thermal conductivity and corrosion resistance, aluminum circles serve as high-performance raw materials for wheel covers, decorative trims, heat shields and sealing gaskets. The material withstands thermal expansion and mechanical stress, protecting precision internal components from high temperatures in engine compartments.

Lighting & Reflectors: The high-purity aluminum surface achieves excellent reflectivity after polishing or anodizing, making it ideal for lamp shells, LED heat sinks and lighting reflector discs. The precision flatness tolerance ensures consistent light distribution in commercial and industrial lighting fixtures.

Industrial Processing: Aluminum circles are extensively used for stamping blanks in general metal fabrication, including bottle caps, container lids, basins, buckets and various hardware components. The smooth edge quality and burr-free precision cutting reduce secondary processing time and improve production efficiency.

Packaging & Consumer Goods: Lightweight, non-toxic and easy to form, our aluminum discs are processed into cosmetic container components, electronic device housings and decorative accessories for consumer goods and architectural decoration sectors.

Yongsheng offers one-stop customized Aluminum Circle and Aluminum Disc solutions. Available alloys include 1000, 3000 and 5000 series such as 1050, 1060, 3003, 3004, 5052 and 5005. Custom thickness from 0.3mm to 6.0mm and diameter ranging 80–1600mm are fully supported. Special sizes outside this range can be discussed upon request.

Surface Finish Customization: Choose from mill finish, brushed, anodized or bright finish according to your downstream processing requirements. We can adjust surface roughness parameters to optimize coating adhesion for PTFE, ceramic or other non-stick coating systems.

Temper & Mechanical Property Customization: Available tempers include O (soft), H12, H14, H16, H18, H22, H24 and H26. Different temper options balance formability and strength for specific deep drawing depths, spinning speeds and stamping forces. Mechanical properties remain stable with tensile strength of 105–145MPa and elongation ≥14% across all temper options.

Alloy & Purity Customization: We source premium-grade primary aluminum ingots to achieve purity levels of 99.60%, 99.70% and up to 99.90% for demanding food-grade and aerospace-grade applications. Custom alloy compositions can be developed for specialized industrial requirements.
