Our Copper Alloy Wire Flattener is engineered for precision flat wire production from high-strength copper alloys such as CuSn, CuZn, and CuCrZr. The machine features two horizontal rolls with servo-controlled roll gap, speed, and tension adjustment, ensuring uniform thickness, accurate width-to-thickness ratios, and a smooth surface finish. It is capable of producing standard flat wire sizes, with widths ranging from 0.2 mm to 8 mm and thicknesses from 0.05 mm to 1.5 mm. Designed for both industrial and high-precision applications, the flattener operates at a design speed of up to 500 meters per minute, delivering consistent dimensional accuracy, reliable performance, and optimized material handling.
The CRM2026 series copper alloy wire flattening machine is designed for high-precision rolling and flattening of copper and copper alloy wires.
It features high speed, stable operation, precise thickness control, and intelligent PLC automation, making it suitable for large-scale industrial production.
This equipment is widely used in the production of CuSn, CuZn, CuCrZr and other alloy strips for electrical, electronic, automotive, and new energy industries.

The Copper Alloy Wire Flattening Machine is designed for processing high-strength copper alloys such as CuSn, CuZn, and CuCrZr.
It is widely used to produce precision flat wires for industrial components, electrical connectors, springs, and high-performance electronic parts.
With its high-rigidity rolling structure and precision control system, the machine ensures:
Uniform deformation during rolling
Accurate width-to-thickness ratio
Smooth and defect-free surface finish
Stable dimensional tolerance at high speed
These features make the equipment ideal for applications that require high dimensional accuracy, excellent conductivity, and reliable mechanical performance.
The copper flattener uses two horizontal rolls with servo-controlled adjustment, supported by Siemens servo motors and drives, to manage roll gap, rolling speed, and tension. Operators can maintain tight tolerances even at a design speed of up to 500 meters per minute.
Key control components include:
Automated tension control and hydraulic gap adjustment minimize surface defects and ensure consistent flat wire thickness and width for all copper alloy grades.
Our copper alloy wire manufacturing machine accommodates a wide range of copper alloys, including:

This machine processes a wide range of copper alloys, including:
The copper flattener preserves ductility and dimensional stability across all alloys, delivering consistent wire thickness and precise tolerances during your production.
The copper alloy wire flattening process begins with high-strength copper alloy rods such as CuSn, CuZn, or CuCrZr. The wire is first pre-straightened and fed into the 2-roll or multi-roll flattener, where servo-controlled roll gap, speed, and tension ensure uniform deformation without surface defects.
During rolling, the machine maintains precise width-to-thickness ratios and tight dimensional tolerances. For harder alloys like CuCrZr, intermediate annealing may be used to restore ductility and reduce work-hardening. The wire then passes through finish rollers to achieve a smooth, defect-free surface for the next process.
The flattener supports both coil (standard) and spool take-up methods depending on production needs. Typical payoff weight ranges from 1 ton to 3 tons, compatible with standard wire drums or coils, ensuring smooth feeding, stable tension, and reduced surface damage during production.
The copper alloy flattener includes an inline laser diameter measurement system from Micro-Epsilon, a globally recognized leader in precision wire measurement solutions. We equip our line with the Micro-Epsilon LSTEC series — widely regarded as one of the most accurate laser diameter measurement systems for copper and copper alloy wires.
The LSTEC laser sensor continuously measures the wire’s diameter and crosssection profile with high repeatability and a measurement accuracy of up to ±0.002 mm under production conditions. Realtime data from the laser measurement unit feeds directly into the control system, enabling instant roll gap and tension adjustments to maintain consistent wire geometry.
This laser system integrates seamlessly with the flattener’s servocontrolled rolling mill and automated tension control, supporting highspeed operation up to 600 meters per minute without loss of measurement fidelity. With its advanced signal filtering and adaptive measurement logic, the MicroEpsilon LSTEC ensures reliable feedback even during highspeed flat copper alloy wire production, enhancing dimensional accuracy, surface finish control, and overall process stability.
The Copper Flat Wire Mill is designed for precision flat copper alloy wire production. Each machine undergoes quality control during manufacturing, assembly, and final inspection to ensure consistent width and thickness tolerances and stable operation.
The mill meets multiple international standards, including:
These certifications confirm that the mill meets international performance and safety requirements for industrial, electrical, and high-precision flat copper alloy wire production.
