Product Description

Product Description

Gold-Plated Copper Alloy Wire for Signal Transmission - Ultra-Fine Gauge is an ultra-precision conductor designed to meet the stringent requirements of high-frequency signal lines and miniaturized electronic systems. Featuring a uniform gold plating over a high-conductivity copper alloy core, it offers exceptional corrosion resistance, low contact resistance, and stable transmission even in demanding environments.

Manufactured to tight tolerances with a bright, smooth surface, this wire ensures minimal signal attenuation, making it ideal for advanced communication devices, aerospace systems, and medical instrumentation.

 

Key Features

  • Ultra-fine diameter wire for minimal footprint and precise signal routing

  • High-purity copper alloy core combined with gold plating for superior conductivity

  • Corrosion-resistant finish ensures long-term stability in harsh conditions

  • Low insertion loss and excellent signal integrity across wide frequency ranges

  • Customizable plating thickness and diameter for project-specific requirements

 

Applications

  • High-frequency data transmission cables

  • Miniature flexible printed circuits (FPC)

  • Aerospace and satellite communication harnesses

  • Precision medical diagnostic devices and sensors

  • Microelectronic component interconnects and fine-pitch connectors

 

Quality & Standards

  • Material: Gold-Plated Copper Alloy (customizable gold layer)

  • Surface Finish: Bright, smooth, oxide-free

  • Diameter: Ultra-fine gauge (as small as 0.02mm) with tight tolerance ±0.005mm

  • Compliance: RoHS / ISO9001 / REACH certified

  • Packaging: Micro coils, spools, or cut-to-length for automated assembly
