Silver - plated copper wire combines copper’s high conductivity with silver’s superior electrical performance and corrosion resistance. The pure copper core provides a low - resistance base, while the silver plating enhances conductivity and protects against oxidation. It is widely used in high - frequency electronics, precision connectors, and aerospace wiring systems.​

Standard Designations​

Material Standards:​

Copper: Complies with ASTM B3 (electrolytic tough - pitch copper).​

Silver plating: Follows ASTM B700 (electrodeposited silver coatings).​

Electrical conductors: Meets IEC 60228 and MIL - STD - 1580 standards.​

Key Features​

Ultra - high conductivity: Enables minimal signal loss in high - frequency applications.​

Excellent corrosion resistance: Silver plating resists oxidation and chemical erosion.​

High - temperature stability: Maintains performance in elevated temperature environments.​

Good solderability: Facilitates reliable connections in precision assembly.​

Low contact resistance: Ensures stable electrical signal transmission.​
