1、 Weldable nickel plating vs. non weldable nickel plating
Weldable nickel plating is an industrial material that deposits a layer of nickel on the surface of copper foil. It is widely used in fields such as electronics, electrical appliances, and communications. Unlike weldable nickel plating,
Non welding nickel platingIt refers to coating a layer of pure nickel on the surface of copper foil, suitable for some scenarios that do not require high welding performance.
The nickel content range for weldable nickel plating is 80-90%, while non weldable nickel plating is 100% pure nickel. This is very important because the difference in nickel content will have a significant impact on its welding performance. Normally, with a nickel content of 80-90%
Weldable nickel platingIt is easier to achieve better welding results because adjusting the nickel content appropriately can improve the stability and reliability of the welding process.
2、 Product specifications and performance parameters
1. Product width: The width of products that can be welded with nickel plating and non welded with nickel plating does not exceed 600mm, suitable for industrial needs of different sizes.
2. Product thickness: The thickness range of products that can be welded nickel plated and non welded nickel plated is 0.012~0.15mm, which can meet applications with different thickness requirements.
3. Nickel plating thickness: The thickness of the nickel plating layer that can be welded is not less than 0.4 µ m, while the thickness of the nickel plating layer that cannot be welded is not less than 0.2 µ m. The difference in nickel plating thickness is mainly to meet the needs of different products and ensure the stability of their performance and functionality.
4. Nickel content of nickel plating layer: The nickel content of nickel plating layer that can be welded is around 80-90%, while non welded nickel plating is 100% pure nickel. The nickel content of the nickel plating layer will affect the quality and stability of the welding. According to the requirements of different welding processes, better welding results can be achieved by adjusting the nickel content.
5. Surface resistance after nickel plating (Ω): The surface resistance of weldable nickel plating does not exceed 0.1 Ω, while the surface resistance range of non weldable nickel plating is between 0.05~0.07 Ω. The magnitude of surface resistance is directly related to the stability of current conduction and electrical performance, so the selection of nickel plated copper foil needs to be based on specific application requirements.
6. Adhesion: The adhesion of both weldable nickel plating and non weldable nickel plating is 5B, which means very good adhesion. Good adhesion is one of the key factors ensuring the stability and durability of nickel plating.
7. Tensile strength and elongation: Both weldable nickel plating and non weldable nickel plating exhibit excellent performance in terms of substrate performance degradation after electroplating. The performance degradation of electroplated substrates with weldable nickel plating shall not exceed 10%, while the performance degradation rate of non weldable nickel plating shall not exceed 6%. This means that
Nickel plated copper foilAfter electroplating, it can still maintain good mechanical properties without affecting the use effect.
3、 Conclusion
Nickel plated copper foil, as one of the most popular industrial materials currently, provides flexible choices for different industries and fields due to its weldability and non weldability. By adjusting parameters such as nickel content and nickel plating thickness, various needs can be met to ensure stable product performance and quality. Nickel plated copper foil plays an important role in electronics, electrical appliances, communication, and other fields, providing reliable support for the development of various industries.
