In the selection of NdFeB strong magnet coating, it is common to plating environment-friendly zinc and nickel. Some customers will ask when selecting the magnet coating that the nickel plating on the magnet (nickel copper nickel) can withstand the salt spray test for 48 hours, and I need to withstand the salt spray test for a longer time, such as 72 hours. Is nickel plating acceptable? Let's introduce it to you.
Can Nd-Fe-B magnet nicuni plating withstand salt spray test for 72 hours?
Nicuni plating is difficult. Some customers have high requirements for salt fog resistance and acid and alkali resistance, such as 72 hours resistance. At this time, Perrin coating can be selected, which is more guaranteed.
Ni-cu-Ni coating shaped special magnet;

Some people still have questions. Why not recommend epoxy?
Salt fog resistance 72 hours, nickel plating and epoxy are not guaranteed, so the recommendation of Parylene.
If you need salt fog resistance for 12 hours, zinc plating is recommended. At present, zinc plating can be divided into white zinc, blue zinc, blue zinc, color zinc and black zinc. At present, the market salt spray test of white zinc 16 hours: blue zinc 24 hours: color zinc 48 hours: black zinc 12 hours.
It is generally recommended that customers use nickel plating after 48 hours of salt spray. At present, the basic process of zinc plating is nickel-copper-nickel, which can ensure that the magnet is not damaged in the case of corrosion.
Above, we introduce to you whether Nd-Fe-B magnet nicuni plating can withstand 72 hours of salt fog test and the recommendation of customers for salt fog resistance hours. I hope it will be helpful to you.
