Intro:

Learn how AgCu alloy wire supports manufacturing of test probes, spring contacts and avionic harnesses — combining conductivity, machinability and durability for defense, medical and aerospace sectors.

Manufacturers of high-reliability assemblies choose AgCu wire when they need a balance of conductivity, surface performance and manufacturability. Its versatility supports both fine-pitch test probes and robust harness components.

 

Manufacturing benefits

• Machinability and formability: AgCu can be drawn and formed to tight tolerances for pins, springs and stamped parts.

• Stable electrical performance: retains a high fraction of copper conductivity with silver-enhanced surface contact behavior.

• Consistent solder/weld behavior: reduces rework and improves yield in automated soldering and laser welding processes.

• Controlled cost for scale: lower silver loading than pure silver makes AgCu attractive for production runs of connectors and cable assemblies.

Use-case examples

• Test fixtures and bed of nails probes: AgCu tips give low contact resistance and long life under repeated cycles.

• Avionics and aerospace harness terminations: reliable contact resistance and solder joints under vibration and thermal cycling.

• Medical device leads and connector pins: sterilizable and solderable conductors with good biocompatible surface when required.

• Precision RF assemblies and sensor interconnects: low-signal-loss conductors for high frequency equipment.

• High-cycle switch and relay contacts: improved wear life and contact stability.

How to specify AgCu for your project

Define target metrics: contact resistance (mΩ), cycle life (cycles), and environmental exposure (salt, humidity).

Choose form factor: fine wire for probe tips, stranded for flexible leads, or strip for stamped contacts.

Test & qualify: request microsection images, contact resistance testing, fretting/fatigue tests, and solderability certification .
