Copper sheet

Copper Sheet - Detailed Description

Material:
Made from high-purity copper, usually *9.9% pure. Common grades include:

• C****0 (Electrolytic Tough Pitch - ETP): High electrical conductivity, widely used in electrical applications.
• C****0 (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.***5 inches or 3.**4 mm) to *0 gauge (0.***0 inches or 0.**4 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 (**0 mm x ***0 mm), 3 ft x 8 ft (**4 mm x ***8 mm), and 4 ft x *0 ft (***0 mm x ***8 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 (H*2): Moderate strength with some flexibility.
• Hard (H*4): 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 B**2/B**2M 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.
