High-Flexibility Gold-Plated Copper Alloy Wire - Ideal for Coil Winding is specially designed to meet the demanding requirements of precision coil manufacturing. Featuring a high-conductivity copper alloy core with a durable gold-plated finish, this wire offers superior flexibility, stable electrical performance, and excellent resistance to mechanical fatigue, making it ideal for tight coil windings and dynamic electromagnetic applications.
Manufactured with a smooth, oxide-free surface and tight diameter control, it ensures reliable winding, bonding, and long-term stability even in complex designs.
Superior flexibility allows for tight, uniform coil windings without cracking
Gold plating enhances conductivity and corrosion resistance for long service life
High mechanical strength supports dynamic and repetitive winding applications
Bright, smooth surface improves bonding, soldering, and insulation compatibility
Customizable diameter and plating thickness options for specific coil designs
High-frequency inductors and transformers
Micro coils for medical devices, sensors, and aerospace components
Electromagnetic coils for wireless charging and energy harvesting systems
Precision wound coils in telecommunications and RF modules
Dynamic windings in robotics, automation, and portable electronics
