Silver Coated Copper Tape High Conductivity for Electrical Shielding & Precision Connections
Product Description
Silver – Plated Copper Strip
Product Overview
Silver – plated copper strip integrates the high conductivity of pure copper with the enhanced electrical performance and corrosion resistance of silver plating. The copper base provides a stable low – resistance foundation, while the uniform silver plating layer improves surface conductivity and oxidation resistance. It is widely used in electromagnetic shielding, high – frequency transformers, lithium – ion battery tabs, and precision electrical components.
Standard Designations
- Material Standards:
- Copper base: Complies with ASTM B152 (copper sheet and strip standards).
- Silver plating: Follows ASTM B700 (electrodeposited silver coatings).
- Electrical materials: Meets IEC 61238 and MIL – STD – 883 standards.
Key Features
- Superior surface conductivity: Silver plating ensures low signal loss in high – frequency applications.
- Excellent electromagnetic shielding: Blocks interference in sensitive electronic systems.
- Strong corrosion resistance: Resists oxidation and humidity in harsh environments.
- High dimensional precision: Uniform thickness and flatness for consistent performance.
- Good formability: Can be cut, bent, and stamped into custom shapes.
