In modern kitchenware manufacturing, cookware aluminum circles serve as a key raw material for pots, frying pans, milk pans, steamers, and more. Their properties directly determine the thermal conductivity, heat resistance, and formability of the cookware. Common alloys include 1050, 1060, 1100, 3003, and 5052. Among them, the 1050 aluminum circle stands out with excellent high-temperature resistance, outstanding workability, and stable chemical characteristics, making it the preferred material for cookware production.

Aluminum circles are typically available in drawn, cast, or anodized forms.

Drawn aluminum circles are produced by spinning or stamping. Since 1050 aluminum is relatively soft, it is often alloyed with small amounts of magnesium, copper, or bronze to improve strength. 1050 drawn circles are widely used for soup pots, steamers, and frying pans.

Cast aluminum is thicker and less thermally conductive than drawn aluminum, and is therefore used for heavy cookware such as soup pots, Dutch ovens, and roasting pans.

1050 anodized aluminum circles form a natural oxide layer through electrolytic processing, which increases surface hardness and prevents reactions with other substances. They are commonly used in juice pots, stew pots, and roasting pans.

Why choose aluminum circles for cookware production?

Excellent thermal conductivity : ensures even heating and prevents localized burning.

High temperature resistance : withstands repeated heating cycles without softening or deformation.

Safe and non-toxic : no harmful metal migration; compliant with food contact standards.

Outstanding processing performance : suitable for deep drawing, spinning, polishing, and anodizing to meet diverse cookware design requirements.

1050 Aluminum Disc Product Information

Performance Advantages of 1050 Pure Aluminum Circles

1. High purity and thermal stability
   Belonging to the 1000 series, 1050 alloy contains over 99.5% aluminum. Higher purity ensures better corrosion resistance and thermal stability. Even under prolonged cooking heat, 1050 aluminum maintains structural integrity, ensuring cookware durability.

2. Superior thermal conductivity
   With a thermal conductivity of about 237 W/m·K, 1050 alloy far outperforms stainless steel, enabling fast and uniform heat transfer, thus enhancing cooking efficiency.

3. Excellent forming and ductility
   In the O temper, 1050 aluminum circles offer exceptional deep-drawing and spinning properties. Even for cookware with complex shapes, they ensure high forming yield, smooth surfaces, and minimal risk of cracking.

4. Strong adaptability to surface treatments
   1050 discs are ideal for anodizing, spraying, color coating, and polishing, delivering both functional durability and attractive appearance.

5. Food-grade compliance
   Free of heavy metal release, 1050 alloy fully complies with international food-contact standards (e.g., FDA, LFGB), ensuring cookware safety.

6. Cost-effective
   As a high-purity aluminum alloy, 1050 is relatively low-cost, allowing manufacturers to produce cookware with competitive market pricing.

Other Cookware Aluminum Alloys

3003 Alloy : Higher strength and corrosion resistance compared to 1050, but with slightly lower thermal conductivity. Often used in pressure cookers and cookware requiring greater mechanical strength.

5052 Alloy : Offers higher strength and excellent corrosion resistance but at a higher cost. Typically applied in cookware or industrial products requiring superior durability.
