Integrated Drawing and Rolling Line for Precision Copper Flat Wire: What Materials Can It Process?

        The Integrated Drawing and Rolling Line for Precision Copper Flat Wire is a continuous all-in-one forming system combining wire drawing and precision cold rolling, widely adopted by electromagnetic wire factories, power conductor manufacturers and new energy component producers worldwide. Many clients ask about the material compatibility of this flat wire production line. Below we introduce its processable raw materials and finished conductors.

Main Processed Copper Materials

1.Oxygen-Free High-Conductivity Copper (OFHC / OF Copper)

       High purity oxygen-free copper is the most popular raw material. It features ultra-low oxygen content, excellent electrical conductivity, good ductility and stable surface quality. It is the preferred material for high-end EV hairpin flat wire, continuously transposed conductors (CTC) for ultra-high voltage transformers and high-grade enameled rectangular magnet wire.

2.Electrolytic Tough Pitch Copper (ETP Copper, C11000)

       Standard industrial electrolytic copper, cost-effective with reliable conductivity. Suitable for mass production of general transformer copper flat wire, paper-covered rectangular conductors, reactor windings and common electrical busbar preform.

3.Copper Alloys (Customized)

       The line can be adjusted to process brass, cupronickel and silicon-copper alloy wire for special electrical and electronic parts, when customers require higher mechanical strength and wear resistance.

Optional Extended Materials (Optional Custom Configuration)

       With roll and tension system upgrade, this integrated drawing rolling line also supports:

       Electrical grade aluminum & aluminum alloy round rod for aluminum flat conductor

       Soft non-ferrous alloy wire for special precision flat profiles

Finished Products Made From This Line

       EV motor hairpin copper flat wire (new energy vehicle drive motor stator winding)

       CTC Continuously Transposed Conductor for large power transformers

       Enameled rectangular magnet wire

       Paper wrapped copper flat wire for oil immersed transformers

       Bare precision copper flat wire for reactors, inductors and electrical connectors

Core Advantages for Different Materials

       This integrated line adopts closed-loop online thickness & width measurement, constant tension control and PLC continuous process adjustment. It can automatically optimize drawing reduction and rolling pass schedule according to different copper material hardness. The finished flat wire achieves tight dimensional tolerance and consistent edge radius, minimizing surface scratches and oxidation. Compared with separated drawing machine and rolling mill, the integrated line reduces material transfer loss, improves yield and cuts labor cost for mass flat wire manufacturing.

Application Industries

       The precision copper flat wire manufactured by this line serves industries including new energy vehicles, power grid & transformer, industrial high-efficiency motors, renewable energy generators and electronic power components.
