Nickel-Plated Copper Flat Braided Wire

As a professional Nickel-Plated Copper Flat Braided Wire manufacturer, Quande offers durable and high-quality products. Select high-purity copper material as the base material of the braided wire. The conventional wire diameter is 0.1mm\0.15mm\0.2mm, which is the basis for ensuring the quality of the final product; copper has good conductivity and ductility.

1. Process of nickel-plated copper braided wire: The raw material copper wire must comply with relevant standards, such as GB/T3953-2009 "Electrical Round Copper Wire", and the wire diameter tolerance is controlled within the range of ±0.005mm;

2. The feed copper wire must be inspected for oxidation and yellowing, and whether there is copper leakage and cracks on the surface. Use a metallographic microscope to observe whether the grain size meets the specified standards;

3. Use an X-ray fluorescence spectrometer to determine the composition of the coating, and conduct bonding tests and salt spray tests to ensure that the coating quality meets relevant standards;

4. Nickel-plated copper braided wire is widely used in the electronic and electrical industry as a semiconductor material. Nickel plating can significantly improve its corrosion resistance, weldability and mechanical properties.
