DC 1100 Aluminum Plate

DC 1100 Aluminum Plate is a variant of the commercially pure AA 1100 aluminum alloy (≥99% aluminum) processed using direct chill (DC) casting, a common method for producing high-quality aluminum ingots. This plate is widely recognized for its excellent corrosion resistance, high thermal/electrical conductivity, and formability, making it suitable for diverse industrial applications.

Key Properties

• Composition: Primarily aluminum (≥99.0%), with trace elements like iron (≤0.95%) and copper (≤0.05%).

• Mechanical Strength: Tensile strength ranges from 75–105 MPa in the annealed (O) temper, increasing to 120–165 MPa with cold working (e.g., H14 temper). Elongation remains high (≥20% in O temper), ensuring ductility for complex forming.

• Thermal/Electrical Conductivity: Among the highest in aluminum alloys, with thermal conductivity ~220 W/m·K and electrical conductivity ~61% IACS, ideal for heat exchangers and electrical components.

• Corrosion Resistance: Exceptional resistance to atmospheric and chemical environments, further enhanced by anodizing.

Applications

• Automotive Industry: Used in lightweight components like transmission housings, radiators, and decorative trim due to its low density and formability.

• Construction: Architectural panels, roofing, and gutters benefit from its corrosion resistance and aesthetic appeal after surface treatments (e.g., embossing, anodizing).

• Electrical & Electronics: Heat sinks, busbars, and wiring harnesses leverage its high conductivity.

• Consumer Goods: Kitchenware, packaging (e.g., foil), and decorative items due to its non-toxicity and workability.

Fabrication & Processing

• Forming: Easily shaped via cold rolling, stamping, or deep drawing. Cold working (e.g., H24 temper) increases strength while maintaining ductility.

• Welding: Excellent weldability with MIG, TIG, or resistance welding, though weld joint strength is slightly lower than base metal.

• Heat Treatment: Annealing at 330–340°C restores ductility in the O temper, while partial annealing (e.g., H22 temper) balances strength and formability.

• Surface Finishes: Common treatments include mill finish, brushing, anodizing (for corrosion protection), and coating (e.g., PVDF for architectural use).

Standards & Specifications

DC 1100 Aluminum Plate adheres to industry standards like ASTM B209(wrought aluminum sheet/plate) and GB/T 3880(Chinese national standard). While "DC" typically refers to the casting method rather than a unique alloy designation, it is often marketed under trade names in regions like China, where it’s produced with tight dimensional tolerances (±5% thickness) and available in thicknesses from 0.2–200 mm.

Pricing & Availability

In 2025, the approximate price for DC 1100 Aluminum Plate ranges from $2,100–$2,900 per metric ton, depending on thickness, temper, and surface finish. Larger orders (e.g., 5+ tons) may qualify for bulk discounts. Major suppliers in China offer customization services, including cutting, punching, and surface treatments, with delivery times averaging 8–14 days.

Summary

DC 1100 Aluminum Plate combines the benefits of pure aluminum—corrosion resistance, conductivity, and formability—with the reliability of DC casting. It serves as a cost-effective solution for applications where high strength is not critical but durability and processability are paramount. Whether in automotive parts, construction, or electronics, its versatility and proven performance make it a staple in modern manufacturing.
