CC 1100 Aluminum Plate

CC 1100 aluminum plate, also known as AA 1100, is a commercially pure aluminum alloy (≥99.0% Al) renowned for its exceptional corrosion resistance, high thermal/electrical conductivity, and formability. Here’s a comprehensive overview:

Composition & Properties

• Composition:

• Aluminum: 99.0–99.95%

• Copper: 0.05–0.20% (minor alloying element)

• Iron/Silicon: ≤0.95% total .

• Mechanical Properties:

• Annealed (O temper): Tensile strength ≥75 MPa, yield strength ≥20 MPa, elongation ≥25% .

• Cold-worked (H18 temper): Tensile strength ≥195 MPa, elongation ≥10% .

• Modulus of Elasticity: 69 GPa .

• Physical Properties:

• Density: 2.71 g/cm³

• Melting Point: ~650°C

• Thermal Conductivity: 222 W/m·K .

Processing & Manufacturing

• Production Methods:

• Hot Rolling: Used for thick plates (up to 500 mm thickness) with stress relief to prevent cutting deformation .

• Cold Rolling: Produces thinner sheets (0.2–8 mm) with improved surface finish and mechanical properties .

• Annealing: Performed at 343°C to enhance formability by reducing internal stresses .

• Surface Finishes:

• Mill finish, mirror polish, or anodized for decorative applications .

Applications

• Industrial: Heat sinks, chemical storage tanks, and food processing equipment due to corrosion resistance .

• Construction: Roofing, cladding, and architectural trim for its lightweight and durability .

• Consumer Goods: Cookware, bottle caps, and decorative items (e.g., nameplates) .

• Electrical: Busbars and wiring for high conductivity .

Fabrication Considerations

• Formability: Excellent for deep drawing, bending, and stamping .

• Weldability:

• Methods: TIG, MIG, or resistance welding. Use 1100 or 4043 filler metal.

• Preheating: Required for thicknesses >6 mm (260–371°C) to reduce thermal stress .

• Machining: Requires sharp tools and low cutting speeds to avoid material galling .

Heat Treatment

• Annealing: Restores ductility after cold working by heating to 343°C .

• Non-Heat Treatable: Cannot be age-hardened; strength improvements come from cold working .

Market & Pricing

• Regional Prices (2025):

• North America: USD 5,400/mt (H14 temper, 0.8 mm thickness, CFR New York) .

• APAC: USD 3,130/mt (CFR Klang Port, Malaysia) .

• Scrap Value: USD 0.74/lb in Houston, Texas .

Sustainability

• Recyclability: 1100 aluminum is infinitely recyclable, requiring only 5% of the energy needed for primary production .

• Environmental Impact: Low carbon footprint due to high recycling rates and energy-efficient production processes .

Comparison with Other Alloys

• AA 6061: Stronger (310 MPa tensile strength) but less conductive and more expensive. Used for structural applications .

• AA 1050: Slightly purer (99.5% Al) but weaker, ideal for chemical containers .

Standards

• Complies with ASTM B209, GB/T 3880, and JIS H 3250 .

In summary, CC 1100 aluminum plate balances cost-effectiveness, versatility, and sustainability, making it a top choice for applications prioritizing corrosion resistance, conductivity, and formability.
