• Excellent Formability — The material has outstanding ductility, making it suitable for spinning, stamping and deep drawing into complex shapes.
• Strong Corrosion Resistance — A natural oxide layer protects the surface, making it suitable for long-term use in humid and outdoor environments.
• High Thermal Conductivity — Suitable for cookware bottoms, lamp reflectors and heat transfer components.
• Smooth Surface Quality — Flat surface with low burr and consistent thickness, ideal for anodizing and precision processing.
• Custom Sizes Available — Diameter, thickness and temper can be customized based on industrial requirements.

Common 1060 Aluminum Circle Tempers

• O Temper (Annealed): Maximum formability, elongation ≥20–43%, ideal for deep drawing.
• H12 / H22: Low to medium strength with good formability.
• H14 / H24: Balanced strength and formability, most widely used temper.
• H18: High strength, limited formability, mainly for flat applications.

Available tempers include O, H12, H14, H16, H18, and H24, allowing flexible selection based on forming depth, strength requirements, and end-use applications.

• Deep drawing required: Choose O temper to prevent cracking and ensure maximum elongation.
• General stamping or bending: H14 provides the best balance of strength and workability.
• High surface reflectivity: DC (hot-rolled) material with finer grain structure is recommended for polishing performance.

Common Surface Finishes of 1060 Aluminum Circle

• Mill Finish: Flat rolled surface for stamping and forming.
• Bright / Reflective: High reflectivity for lighting and decoration.
• Brushed: Textured surface for appliances and cookware.
• Anodized: Corrosion-resistant and harder surface with color options.
• Non-stick Coated: PTFE or ceramic coating for cookware use.
• Color Coated (PE/PVDF): Weather-resistant painted finish for building use.
• Protective Film: Temporary protection during processing and transport.
• Sandblasted: Matte anti-glare finish for electronics and lighting.

How to Choose the Right Surface for 1060 Aluminum Circle

Selecting the appropriate surface treatment depends on the final application:

• Cookware manufacturing: Non-stick coated or brushed finish is recommended.
• Lighting industry: Bright reflective or sandblasted finish provides optimal optical performance.
• Architectural use: Anodized or color-coated surfaces improve durability and aesthetics.
• Industrial stamping: Mill finish with PE/PVC film ensures processing protection.

Haomei Aluminum controls the quality of 1060 aluminum circles from raw material to final packaging. The inspection process includes:

• Alloy composition testing
• Thickness measurement
• Diameter tolerance checking
• Surface quality inspection
• Edge burr inspection
• Mechanical property testing if required
• Packaging inspection before shipment

Our goal is to provide aluminum circles with stable quality, smooth surface and reliable processing performance.

1060 DC Aluminum Circle

DC stands for Direct Chill Casting (hot rolling). In this process, aluminum ingots are heated and rolled at high temperatures.

• Key features: excellent grain structure and high ductility.
• Best use: deep drawing. If you are manufacturing deep pots, pressure cookers, or complex industrial parts that require large deformation without cracking, the DC process is essential.
• Surface quality: generally higher; more suitable for anodizing and polishing.
• Typical applications: high-end cookware, pressure cookers, lighting reflectors, and high-quality electronic components.

1060 CC Aluminum Circle

CC stands for Continuous Casting (cast rolling). This process casts molten aluminum directly into coils, followed by cold rolling.

• Key features: more economical price and slightly higher hardness.
• Best use: spinning and simple stamping. Ideal for products that do not require extreme stretching.
• Surface quality: good, but compared with DC material, more “orange peel” or grainy appearance may occur during deep drawing.
• Typical applications: shallow trays, pot lids, road signs, nameplates, and general household utensils.

Processing Method Requirements

For deep drawing applications such as high-depth cookware or cylindrical parts, O temper is strongly recommended due to its excellent ductility and maximum formability.

For spinning processes or parts requiring moderate strength and better surface stability, H14 or H16 temper is commonly selected to achieve a balance between formability and structural strength.

Strength vs. Formability Balance

Different tempers offer significantly different mechanical properties. H18 temper provides the highest strength but very limited ductility, making it suitable only for simple forming or flat applications.

In contrast, O temper is the softest condition, offering excellent elongation and superior deep drawing capability.

Surface Treatment & Finishing Requirements

If your application requires anodizing, polishing, or mirror finishing, 1060 aluminum is an excellent base material due to its high purity.

In general, H temper materials tend to achieve a more stable and brighter anodized finish, while O temper offers better formability but a relatively softer surface appearance after finishing.

Temper Selection (Forming Performance vs Strength)

• Deep drawing & spinning applications (e.g., cookware, pots, kitchenware): O temper is recommended due to its excellent ductility and maximum formability.
• Structural or load-bearing components (e.g., lamp bases, industrial parts): H24 or H18 temper is preferred for higher rigidity and dimensional stability.

Thickness-to-Diameter Ratio Selection

• Spinning applications: For disc diameters below 500 mm, thickness typically ranges from 0.5–3.0 mm to ensure smooth forming and reduced cracking risk.
• Heavy-duty or pressure-related parts: For higher strength requirements, thickness above 4.0 mm with H24 temper is recommended.

Comparison with Other Aluminum Alloys

• Compared with 1050A aluminum: 1060 offers approximately 5–10% higher tensile strength and improved forming performance, making it more suitable for deep drawing applications.
• Compared with 3003 aluminum: 1060 provides superior electrical and thermal conductivity, while 3003 offers higher mechanical strength for structural applications.

Cost-Effectiveness Consideration

1060 aluminum disc is generally 3–8% more expensive than 1050A, but its superior formability and conductivity make it a more cost-effective solution for applications requiring high precision forming or thermal performance.
