Whether you manufacture electrical components, bus bars, heat exchangers, or precision copper parts, this solution ensures clean cuts, reduced material waste, and reliable operation.
Why Laser Cutting for Copper?
Copper sheets and plates are widely used in electrical, electronics, and thermal management applications, but traditional cutting methods such as mechanical shearing, water jet cutting, and plasma cutting come with several limitations. While these methods can handle copper, they often compromise on accuracy, edge quality, and overall production efficiency.
Challenges in Cutting Copper
Copper is one of the most challenging materials to cut due to its high thermal conductivity and high reflectivity at laser wavelengths. Mechanical shearing causes edge deformation and burrs, requiring extensive secondary finishing. Water jet cutting is slow and produces wet edges that need drying. Plasma cutting generates large heat-affected zones and rough edges unsuitable for precision electrical applications.
Laser Cutting vs Traditional Methods for Copper
High-power fiber laser cutting machines (6kW and above) provide a controlled and precise cutting process for copper sheets. With nitrogen-assisted cutting and optimized parameters, copper can be cut with tight tolerances and clean edges. Compared to traditional methods, laser cutting offers superior dimensional accuracy, minimal heat-affected zones, and the ability to cut complex shapes with repeatable results, making it ideal for electrical bus bars, heat exchangers, and precision components.
Higher Precision and Better Edge Quality
A copper laser cutting machine delivers positioning accuracy of up to ±0.02 mm with bright, oxide-free edges when using nitrogen assist gas. Advanced nesting software helps reduce material wastage and improves sheet utilization. The non-contact cutting process eliminates tool wear and ensures consistent quality across production runs.
Cost-Effective for High-Value Copper Applications
While copper laser cutting requires higher laser power, the superior edge quality, minimal material waste, and elimination of secondary finishing processes make it cost-effective for electrical and electronics manufacturing. Clean cuts reduce scrap rates and improve overall production efficiency, especially for high-value copper applications.

Important Note:
Copper cutting requires minimum 6kW laser power due to high reflectivity at 1064nm wavelength. Lower power lasers (1-4kW) are not recommended for copper as they may damage the laser source due to back-reflection. Always use high-purity nitrogen (99.99%+) at 16-25 bar pressure. Never use oxygen for copper cutting. Explore our high-power fiber laser cutting machines for safe and efficient copper cutting.
