Why Choose Standard Nickel Plating Magnet?

Mature Process, Cost-Effective:

Electroplated nickel has decades of industrial application history with a stable process. Its batch processing cost is lower than that of electroless nickel or multi-layer Ni-Cu-Ni systems, making it suitable for high-volume production of magnetic assemblies.

Good Corrosion Resistance:

The standard nickel coating has a dense structure and typically achieves 120–200 hours in neutral salt spray (NSS) testing, meeting the anti-corrosion requirements for indoor and general industrial environments.

High Hardness and Wear Resistance:

As-plated hardness is approximately 400–600 HV with a smooth surface and strong scratch resistance, suitable for magnets that experience dynamic contact or friction during assembly.

Excellent Solderability and Conductivity:

The nickel coating surface can be directly soldered and offers stable contact resistance, facilitating electrical connection of magnets in electronic circuits.

Good Adhesion:

With optimized pretreatment and nickel plating processes, the coating adheres firmly to the NdFeB substrate, passing adhesion tests such as cross-cut and thermal shock, with no easy peeling or flaking.

Controllable Impact on Magnetic Properties:

Although electroplated nickel itself is weakly ferromagnetic, the coating thickness is very thin (typically 5–20μm), resulting in minimal reduction (typically <1%) of the remanence, coercivity, and maximum energy product of the NdFeB magnet – negligible for the vast majority of applications.
