CC 3003 Aluminum Plate

The CC 3003 Aluminum Plateis a variant of the AA3003 aluminum alloyprocessed using Continuous Casting (CC)technology. Here's a detailed breakdown based on technical specifications and applications:

1. Alloy Composition

• Primary Alloying Elements: AA3003 is an Al-Mn alloy with 1.0–1.5% manganese (Mn)and ≤0.7% iron (Fe), providing moderate strength and excellent corrosion resistance .

• Balance: Aluminum (Al) with trace elements (e.g., Si, Cu, Zn) within standard limits .

• CC Processing: The "CC" prefix refers to the continuous casting method, which affects microstructure but not the alloy's chemical composition .

2. Mechanical Properties

• Strength:

• Tensile Strength: 145–185 MPa (H14 temper) .

• Yield Strength: 125 MPa (H14 temper) .

• Ductility:

• Elongation: 5–8% (H14 temper), balancing formability and durability .

• Hardness:

• Brinell Hardness: 46 HB (H14 temper) .

• Density: 2.73 g/cm³.

• Maximum Working Temperature: 250°C.

Note: CC processing may refine grain structure, improving formability compared to Direct Chill (DC) cast plates .

3. Physical & Chemical Characteristics

• Corrosion Resistance:

• Exceptional resistance to atmospheric, marine, and chemical environments due to the protective aluminum oxide layer .

• Suitable for outdoor applications like roofing and siding .

• Weldability:

• Easily welded via MIG, TIG, or resistance welding, with minimal loss in mechanical properties .

• Formability:

• High ductility allows deep drawing, stamping, and bending for complex shapes .

• Surface Finish:

• Available in mill finish, pre-painted (e.g., fluorocarbon or polyester coatings), or anodized for enhanced aesthetics and protection .

4. Applications

• Construction:

• Building formwork, curtain walls, roofing, and structural components due to corrosion resistance and lightweight properties .

• Automotive:

• Body panels, fuel tanks, and heat exchangers for weight reduction and durability .

• Packaging:

• Beverage cans and food containers due to non-toxicity and corrosion resistance .

• Electrical & Electronics:

• Busbars and heat sinks for high thermal conductivity .

• Industrial Equipment:

• Storage tanks, pressure vessels, and ductwork .

5. Processing & Heat Treatment

• Continuous Casting (CC):

• A manufacturing method that produces uniform microstructure and reduced segregation compared to DC casting .

• Enhances formability and surface quality for applications requiring deep drawing .

• Cold Working:

• Strengthened via cold rolling (e.g., H14 temper), improving tensile strength without heat treatment .

• Annealing:

• Softened (O temper) for maximum ductility, with a tensile strength of 95–135 MPa .

6. Standards & Specifications

• International Standards:

• ASTM B209 (plate/sheet), ASTM B211 (bar/rod), ISO 6361 (architectural applications) .

• Regional Compliance:

• Compliant with Chinese standards (e.g., GB/T 3880) for aluminum sheets .

• Surface Coatings:

• Pre-painted variants meet AAMA 2605 (fluorocarbon) or AAMA 2603 (polyester) standards for weather resistance .

7. Advantages Over Other Alloys

• Cost-Effective: Lower cost than stainless steel while maintaining corrosion resistance .

• Lightweight: Density ~30% lower than steel, ideal for weight-sensitive applications .

• Eco-Friendly: High recyclability with minimal energy loss .

• Design Flexibility: Formable into complex shapes for architectural and industrial designs .

8. Typical Suppliers

• Global: Alcoa, Novelis, Constellium.

• China-Based: Gnee Aluminum, Zhongxin Aluminum, Haomei Aluminum (offering pre-painted CC 3003 coils) .

9. Considerations for Use

• Welding: Use ER4043 filler metal to avoid cracking .

• Surface Protection: Apply coatings (e.g., PVDF) for harsh environments like coastal areas .

• Machining: Requires sharp tools and proper lubrication due to high ductility .

Conclusion

The CC 3003 Aluminum Platecombines the corrosion resistance and formability of AA3003 with the benefits of continuous casting, making it a versatile choice for construction, automotive, and industrial applications. Its standardized properties and cost-effectiveness position it as a reliable material for projects requiring lightweight, durable, and aesthetically appealing solutions.
