Understanding 1000 Series Aluminum Circles

1000 series aluminum circle discs, also known as pure aluminum alloy circles, belong to the 1000 series aluminum alloy products. Their purity can reach over 99.00%, making them one of the highest aluminum-content alloys in the entire series. Since they contain no other alloying elements, the production process is relatively simple and the price is comparatively affordable.

The most common 1000 series aluminum circle grades include 1050 aluminum circle , 1060 aluminum circle, 1070 aluminum circle, 1100 aluminum circle, and 1200 aluminum circle. As industrial pure aluminum, these discs feature excellent plasticity, corrosion resistance, electrical conductivity, and thermal conductivity, but with relatively low strength. Anodized aluminum circles almost never discolor, which is a valuable characteristic.

Definition of 1000 Series Pure Aluminum Alloy Round Sheets

The last two digits of the 1000 series aluminum sheet model name determine the minimum aluminum content for that model. For example, the last two digits of the 1050 series are 50. According to international naming standards, an aluminum content of 99.5% or higher is required to qualify. my country's aluminum alloy technical standard (GB/T3880-2006) requires an aluminum content of 99.5% for 1050 aluminum sheet. Similarly, the aluminum content of 1060 aluminum plate must also be at least 99.6%.

Key Features of 1000 Series Aluminum Circles

1. Excellent deep drawing performance
   In O temper (annealed condition), the circles have outstanding plasticity, suitable for various deep drawing and spinning processes without cracking or wrinkling.

2. Superior surface quality
   After precision rolling and annealing, the surface is smooth and clean, free from scratches or oil stains, meeting the requirements of high-end cookware and lighting applications.

3. High processing efficiency
   Stable raw material properties ensure low processing loss, helping to reduce overall manufacturing costs.

4. Eco-friendly and recyclable
   Aluminum is nearly 100% recyclable, aligning with green manufacturing and sustainability goals.

5. Corrosion resistance
   The natural oxide film of aluminum provides excellent protection against environmental corrosion.

6. Outstanding thermal conductivity
   With high heat conductivity, aluminum ensures efficient heat transfer. 1000 series circles are widely used in cookware and heat exchangers that require quick, uniform heating.

7. Customizable options
   Available in various diameters, thicknesses, and surface treatments, offering tailored solutions to meet customer-specific needs.

Applications of 1000 Series Pure Aluminum Alloy Circles

• Cookware: widely used in producing pots, frying pans, pressure cooker inner liners, and other kitchen utensils. The excellent ductility allows stamping and pressing into various shapes.

• Lighting: ideal for lamp shades, reflectors, and decorative lighting components. Surfaces can be polished, anodized, or mirror finished for superior reflectivity.

• Signs & Nameplates: lightweight, durable, and easy to fabricate for signage, plates, and labels.

• Traffic Signs: commonly used as substrates for road and traffic signage due to their durability, weather resistance, and high visibility. They can also be coated with reflective materials for night visibility.

• Reflective Devices: thanks to high reflectivity and corrosion resistance, used in reflective bowls, mirrors, automobile headlights, and solar reflectors.

• Industrial Applications: applied in chemical processing equipment, storage tanks, and heat exchangers for their corrosion resistance and thermal conductivity.

Production Process & Quality Control

Production flow:
Casting → Hot rolling → Cold rolling → Annealing → Slitting → Circle punching → Deburring → Inspection → Packaging

• Advanced equipment: fully automatic punching lines ensure high precision.

• Strict inspection: full control from chemical composition to mechanical properties and surface quality.

• Standard packaging: moisture-proof, anti-oxidation, shock-proof packaging ensures safe export transportation.

Comparison with Other Series Aluminum Circles

Vs 3000 series (3003, 3105): 1000 series has better ductility, but slightly lower strength.

Vs 5000 series (5052, 5754): 1000 series offers lower cost and easier processing, but reduced corrosion resistance and strength compared to magnesium alloys.

Best choice when strength requirements are not high, but excellent formability and cost-efficiency are needed.
