Copper Sheet - Detailed Description

Material:
Made from high-purity copper, usually 99.9% pure. Common grades include:

C11000 (Electrolytic Tough Pitch - ETP): High electrical conductivity, widely used in electrical applications. C12200 (Phosphorus-Deoxidized): Excellent for plumbing and industrial applications due to improved corrosion resistance and weldability.

Thickness:
Copper sheets come in various thicknesses, often measured in:

Gauge: Common gauges range from 8 gauge (0.1285 inches or 3.264 mm) to 30 gauge (0.0100 inches or 0.254 mm). Millimeters or Inches: Ranges from 0.2 mm (very thin) to 6 mm (thicker sheets).

Sizes:

Standard sheet sizes are 2 ft x 4 ft (610 mm x 1220 mm), 3 ft x 8 ft (914 mm x 2438 mm), and 4 ft x 10 ft (1220 mm x 3048 mm). Custom sizes available on request.

Temper/Hardness:

Soft (Annealed - O Temper): Flexible and easy to bend, ideal for decorative applications or forming. Half-Hard (H02): Moderate strength with some flexibility. Hard (H04): Rigid, suitable for structural or load-bearing applications.

Finish Options:

Mill Finish: Raw, unfinished surface, slightly rough. Polished: Smooth, shiny surface for decorative uses. Brushed: Matte finish with fine lines, common in interior design. Patina/Antique Finish: Chemically treated for an aged or oxidized look.

Properties:

High electrical and thermal conductivity: Excellent for electrical and heat transfer applications. Corrosion-resistant: Forms a natural protective layer, ideal for outdoor and marine environments. Malleable and ductile: Easy to shape, cut, and solder. Antimicrobial: Naturally inhibits bacteria, great for sanitary environments.

Applications:

Electrical: Busbars, grounding systems, and circuit components. Roofing & Cladding: Durable and aesthetic for architectural projects. Plumbing: Flashing, guttering, and waterproofing. Decorative: Kitchen backsplashes, countertops, and artwork. Industrial: Heat exchangers, chemical processing, and automotive components.

Standards & Certifications:

Conforms to ASTM B152/B152M for copper sheet and plate standards. RoHS-compliant for environmental safety and often lead-free.

Packaging:

Supplied in flat sheets or rolled coils. Protected with plastic film or paper interleaving to prevent scratches. Larger sheets may come in wooden crates for safe transport.
