Silver Coated Copper Tape High Conductivity for Electrical Shielding & Precision Connections
Product Overview
Silver-plated copper strip combines the high conductivity of pure copper with enhanced electrical performance and corrosion resistance from silver plating. The copper base provides a stable low-resistance foundation, while the uniform silver plating improves surface conductivity and oxidation resistance. Ideal for electromagnetic shielding, high-frequency transformers, lithium-ion battery tabs, and precision electrical components.
Standard Specifications
- Copper base complies with ASTM B152 (copper sheet and strip standards)
- Silver plating follows ASTM B700 (electrodeposited silver coatings)
- Meets IEC 61238 and MIL-STD-883 standards for electrical materials
Key Features
- Superior surface conductivity for low signal loss in high-frequency applications
- Excellent electromagnetic shielding for sensitive electronic systems
- Strong corrosion resistance in harsh environments
- High dimensional precision with uniform thickness and flatness
- Good formability for custom cutting, bending, and stamping
