Manufacturing Process
This product is manufactured using Clad & Weld process with metallurgical bonding. It is NOT electroplated.
Metallurgical bonding creates a permanent metallurgical connection, ensuring stable reliability compared to electroplating. This enables excellent weldability, designed to resist peeling during bending, and stable performance under thermal cycling conditions.
What is Copper Clad Aluminum Flat Wire?
Copper Clad Aluminum Flat Wire is a Copper Clad Aluminum (Cu/Al) material with 65% IACS conductivity, , widely used in Industrial Motors, Photovoltaic Solar, Automotive/EV, and other applications. It combines the excellent properties of multiple metals, making it an ideal alternative to traditional single-metal materials.
