Everything You Need to Know About Copper Sheets in 2025


Copper sheets are versatile materials widely used in construction, electronics, and art due to their excellent conductivity and durability. This guide covers everything from sourcing to applications.


How to Find Reliable Copper Sheets from China in 2025


China remains a top supplier of copper sheets, offering competitive pricing and quality. To find reliable manufacturers:

  • Verify certifications like ISO 9001
  • Check customer reviews on Alibaba or Global Sources
  • Request material test reports
  • Compare MOQs and lead times

What Buyers Should Know Before Buying Copper Sheets from China


Key considerations include:

  • Thickness tolerance (±0.05mm is industry standard)
  • Surface finish options (brushed, polished, oxidized)
  • Packaging standards for international shipping
  • Payment terms (30% deposit is common)

Types of Copper Sheets


Common varieties include:

  • C11000 (Electrolytic Tough Pitch) - 99.9% pure
  • C12200 (Phosphorus Deoxidized) - better weldability
  • Clad copper - aluminum or steel core

Functions and features of Copper Sheets


Key properties:

  • Thermal conductivity: 401 W/m·K
  • Electrical conductivity: 100% IACS
  • Corrosion resistance (forms protective patina)
