CuAg03 is a silver-bearing copper alloy wire with approximately 0.3% silver content. It offers enhanced softening resistance and mechanical strength while maintaining high electrical conductivity. The alloy is designed for applications requiring stable electrical performance under thermal stress, making it ideal for precision connectors and signal transmission systems.
Electrical conductivity ≥ 96% IACS
Higher softening temperature than pure copper
Improved fatigue resistance and mechanical durability
Excellent formability and corrosion resistance
RoHS and REACH compliant
High-frequency coaxial cables
Relay terminals and signal contacts
Automotive sensors and wire harness systems
RF/microwave conductors
High-reliability consumer electronics
Complies with ASTM standards (C11600 series)
Batch-inspected for tensile strength, elongation, and conductivity
ISO 9001 certified manufacturing
RoHS & REACH environmental compliance
Precision spools for small diameters
Coils or wooden reels for larger quantities
Moisture-resistant packaging for export
OEM/custom branding available upon request
