Copper sheet is a common metal material, so do you know the production process of copper sheet?

To ensure the quality and performance of copper sheets, the requirements of the manufacturing process are critical. 


The following is a detailed introduction to the process requirements for manufacturing copper sheets:

Raw material selection:

The quality and performance of copper sheet begins with the selection of raw materials. Usually, copper sheets are manufactured using high-purity oxygen-free copper (Oxygen-Free Copper, OFC), which has excellent electrical and thermal conductivity. At the same time, it should also be ensured that the raw material does not contain impurities, oxides or other harmful substances, which will reduce the conductivity of the copper sheet.

Cutting and processing:

Cutting and machining is one of the key steps in making copper sheet. Precise size and smooth surface are the basis to ensure the quality of copper sheet. Common cutting methods include shearing, punching and chipping. During cutting, proper cutter and process parameters should be used to avoid scratches or deformation.

Surface treatment:

The finish of the copper sheet is critical to its performance and appearance. Typically, copper sheets are given a surface treatment such as polishing, grinding or plating to ensure a smooth, clean surface and to remove any oxides. Surface treatment can also improve the corrosion resistance of copper sheet, making it suitable for different application fields.

Heat treatment:

Heat treatment can improve the mechanical properties of copper sheet. By controlling temperature and time, the hardness, strength and toughness of the copper sheet can be tuned to meet specific application needs. Heat treatment also helps to relieve internal stress and improve the stability of the copper sheet.

Rolling and stretching:

In order to obtain the desired dimensions and properties, copper sheets usually require deformation processes such as rolling and stretching. These processes can vary the thickness and mechanical properties of the copper sheet and ensure its uniformity. The rolling and stretching process requires careful control to avoid cracks and deformation.

Testing and Quality Control:

Every stage of manufacturing copper sheets requires rigorous testing and quality control. Common inspection methods include ultrasonic testing, X-ray testing, and metallographic analysis to ensure that the copper sheet is free of internal defects. In addition, dimensions, flatness and surface quality need to be checked to ensure that the product meets specifications.

Packaging and storage:

Copper flakes should be properly packaged and stored after manufacture. Packaging should protect the copper foil from contamination, moisture and physical damage. Packaging materials such as plastic film, foam pads or cartons are usually used. Additionally, copper sheets should be stored in a dry, well-ventilated environment away from direct sunlight and extreme temperatures.

Environmental protection and safety:

The manufacture of copper sheets should comply with environmental regulations and ensure safety in the production process. Both the disposal of waste and the disposal of wastewater require compliance. At the same time, employees should be properly trained to ensure their safety and health.


The above are the manufacturing process requirements of copper sheets, and following these process requirements will help ensure the quality, performance and reliability of copper sheets to meet the needs of various application fields. The manufacture of copper flakes is a delicate process that requires strict control and a high degree of expertise to ensure the superior performance of the final product.
