CC 1060 Aluminum Plate

CC 1060 Aluminum Plate refers to a high-purity aluminum alloy (99.6% Al) processed through a Cold-Crolled (CC)manufacturing method, which enhances its mechanical properties and surface finish compared to hot-rolled alternatives. This alloy is part of the 1000 series, known for its excellent corrosion resistance, electrical/thermal conductivity, and formability. Below is a comprehensive breakdown of its key attributes:

Composition

• Aluminum (Al):99.6% minimum

• Impurities (total):≤0.4% (Fe ≤0.35%, Si ≤0.25%, Cu ≤0.05%, Mg ≤0.03%).

• High purity ensures superior conductivity (55% IACS) and corrosion resistance, making it ideal for electrical and chemical applications.

Physical Properties

• Density:2.7 g/cm³

• Thermal Conductivity:230 W/m·K

• Electrical Conductivity:55% IACS (comparable to pure copper)

• Melting Point:650–660°C

• Coefficient of Thermal Expansion:24 µm/m·K

Applications

1. Electrical Industry:Bus bars, transformer windings, and electrical conductors due to high conductivity.

2. Construction:Architectural panels, roofing, and curtain walls for corrosion resistance and lightweight properties.

3. Automotive & Aerospace:Heat exchangers, radiator fins, and structural components requiring formability.

4. Consumer Goods:Kitchenware, lamp holders, and decorative items (e.g., anodized finishes).

5. Chemical Equipment:Storage tanks and pipelines for resistance to acids/alkalis.

Manufacturing Process

1. Casting:Aluminum ingots are produced via continuous casting for uniform structure.

2. Hot Rolling:Preheated ingots are rolled to reduce thickness and improve formability.

3. Cold Rolling (CC):Further reduction in thickness at room temperature to enhance strength and surface smoothness.

4. Annealing (for O temper):Heat treatment to soften the material and restore ductility.

5. Surface Treatment:Options include anodizing, powder coating, brushing, or embossing for decorative or protective purposes.

Standards

• ASTM B209(plate/sheet), EN 573-3(European), GB/T 3880.1(Chinese), and JIS H4000(Japanese).

• Equivalent Grades:AA 1060, UNS A91060, ISO Al 99.6.

Surface Finishes

• Mill Finish:Natural surface after rolling.

• Anodized:Enhanced corrosion resistance and decorative color options.

• Powder Coated:Durable finish for outdoor applications.

• Brushed/Polished:Improved aesthetics for architectural use.

Advantages

• High Purity:Excellent corrosion resistance without additional coatings.

• Formability:Easily stamped, bent, or welded (gas metal arc welding recommended).

• Cost-Effective:Lower cost than alloyed aluminum grades (e.g., 6061, 7075) due to simple processing.

• Recyclability:100% recyclable with minimal loss of properties.

Limitations

• Low Strength:Not suitable for high-stress applications without cold working.

• Machinability:Poor in annealed (O) state; improved in harder tempers (e.g., H18) with carbide tooling.

• Surface Sensitivity:Prone to scratches in soft tempers; requires protective films during handling.

Market Trends

• Price (2025):Approximately $1,780–$1,910 per tonfor 3mm thick plates in China.

• Demand Drivers:Growth in renewable energy (solar panels, EV charging infrastructure) and lightweight construction materials.

• Regional Production:China is a major producer, with suppliers offering custom sizes up to 2650mm width and 500mm thickness.

Specification Example

• Thickness:0.2–500 mm

• Width:100–2650 mm

• Length:500–16,000 mm

• Temper:O, H12, H14, H18, H22, H24, etc.

• Surface Protection:PE film, paper interleaving, or PVC coating.

Conclusion

CC 1060 Aluminum Plate is a versatile, cost-effective material valued for its high purity, conductivity, and formability. Its applications span electrical, construction, and industrial sectors, leveraging both its mechanical properties and ease of processing. Cold rolling enhances its strength for structural use, while surface treatments further expand its decorative and protective capabilities. When specifying CC 1060, consider the temper, thickness, and surface finish to meet project requirements.
