DC 1060 Aluminum Plate

DC 1060 Aluminum Plate refers to a commercially pure aluminum alloy (99.6% Al)processed using the Direct Chill (DC) casting method. Here’s a detailed breakdown based on industry standards and applications:

1. Composition and Standards

• Chemical Composition:

• Aluminum (Al): ≥99.6%

• Impurities (Fe, Si, Cu, etc.): ≤0.4% total .

• Standards:

• Complies with ASTM B209(wrought aluminum sheet/plate), EN 573(chemical composition), and ISO 6361(wrought aluminum products) .

• Alloy Designation: Also known as AA 1060or UNS A91060, with "DC" specifying the casting process rather than a unique alloy variant .

2. Direct Chill (DC) Casting Process

• Production:

• Molten aluminum is poured into a mold and cooled using water jets, producing a solid ingot with uniform structure.

• Unlike Continuous Casting (CC), DC casting allows for thicker plates(up to 500 mm) and better formability for deep drawing .

• Advantages:

• Superior formabilityfor complex shapes (e.g., cookware, automotive parts) .

• Lower residual stresscompared to CC, reducing warping during cutting .

• Cost: Typically 20-30% more expensivethan CC-processed 1060 due to longer production cycles .

3. Mechanical and Physical Properties

• Tensile Strength: 55–90 MPa (annealed, O temper) to 110–136 MPa (cold-worked, H24 temper) .

• Yield Strength: 35 MPa (O temper) to 80 MPa (H18 temper) .

• Elongation: 12–30% (O temper), ideal for bending and stretching .

• Hardness: 28–36 HB (O temper) to 30–40 HB (H18 temper) .

• Density: 2.7 g/cm³, with high thermal conductivity (237 W/m·K)and electrical conductivity (62.7% IACS).

4. Applications

• Electronics: Bus bars, capacitors, and heat sinks due to high conductivity .

• Construction: Curtain walls, roofing, and signage for corrosion resistance and lightweight properties .

• Kitchenware: Deep-drawn pans and utensils (DC casting enhances deep drawability) .

• Chemical Equipment: Resistant to mild acids and alkalis .

5. Advantages Over Other Alloys

• Corrosion Resistance: Forms a protective oxide layer, suitable for marine and outdoor environments .

• Weldability: Easily joined via MIG, TIG, or spot welding .

• Cost-Effective: Cheaper than alloyed grades (e.g., 3003, 5052) for non-structural applications .

6. Limitations

• Low Strength: Not suitable for high-stress applications (e.g., aerospace components) .

• Machinability: Requires sharp tools due to softness, though improved in harder tempers (H16, H18) .

7. Surface Finishes

• Mill Finish: Smooth, as-produced surface for general use.

• Brushed/Polished: Matte or glossy finishes for decorative applications.

• Anodized: Enhances corrosion resistance and aesthetic appeal (e.g., architectural cladding) .

8. Comparison with CC (Continuous Casting)

• Formability: DC plates excel in deep drawing (e.g., cookware), while CC plates are better for simple stamping .

• Surface Quality: DC plates have finer grain structureand fewer defects after anodizing .

• Thickness Range: DC supports thicker plates (up to 500 mm) vs. CC (typically ≤6 mm) .

9. Specifications

• Thickness: 0.2–500 mm

• Width: 200–3150 mm

• Length: 500–12,000 mm (customizable) .

10. Handling and Storage

• Avoid contact with chloride-containing materials to prevent pitting.

• Store in dry environments to maintain surface integrity .

In summary, DC 1060 Aluminum Plate is a versatile, cost-effective material valued for its high purity, corrosion resistance, and formability, with the DC casting process optimizing it for demanding applications like deep drawing and architectural design.
