Process Characteristics: High-precision rolling can ensure the uniform thickness and smooth surface of the copper strip. We can provide products with a thickness range from 0.10 mm to 2.0 mm.
2. Annealing
Process Introduction: Annealing is to eliminate the internal stress generated during the rolling process, improve the ductility and plasticity of the copper strip, and make it less likely to break during subsequent processing.
Process characteristics: The annealed copper narrow strip is more flexible and suitable for the production of precision electronic components. We provide soft, medium-hard, and hard copper strip products according to customer needs.
3. Cutting and Slitting
Process Introduction: After rolling and annealing, the copper strip will be cut into strips to the required width. The high-precision slitting process ensures the stability and consistency of the width dimension.
Process Features: The slitting process can provide copper strips with a width range of 10 mm to 300 mm to meet the needs of different customers.
4. Surface Treatment
Process Introduction: The copper strip can be surface-treated according to different applications, such as bright annealing, wire drawing, or tinning. Surface treatment not only enhances the corrosion resistance of the copper strip but also improves its aesthetics and weldability.
Process Features: Bright copper strips are often used for decorative materials, while tinned copper strips are used for welding parts in electrical equipment.
5. Surface treatment types of copper strips
To meet different application requirements, copper narrow strips can be subjected to a variety of surface treatments to increase their durability and aesthetics in specific environments. The following are several common surface treatment methods:
1. Bright Surface Treatment (Bright Surface Treatment)
Features: Through polishing, the surface of the copper narrow strip is smooth and bright, suitable for decorative fields with high requirements for appearance.
Application: Mainly used in building decoration materials, interior design, furniture decoration, etc.
2. Oxidation Protection (Oxidation Protection)
Features: Through oxidation treatment, the corrosion resistance of copper narrow strips is significantly improved, and it is suitable for applications in humid or acidic environments.
Application: Suitable for outdoor building materials, electrical equipment housings, and other parts that need to be exposed to harsh environments for a long time.
3. Tinned Copper Treatment (Tinned copper)
Features: After the copper narrow strip is tinned, its surface oxidation resistance is greatly improved, and the welding performance is enhanced.
Application: Commonly used in products that require welding, such as cable conductors, electronic components, and electrical connectors.
