While choosing the plating of strong neodymium magnets, Zinc and Nickel are the common plating. When some customers choose plating, they will ask “can nickel plated pass salt spray test for 48 hours?”,“I need a longer time of salt spray test, such as 72 hours, can nickel plated magnets achieve it? ”.
Can nickel plated neodymium magnets resist salt spray test for 72 hours?
There are some difficulties if using nickel plated magnets for 72-hour-spray test. Some customers have high requirements about the resistant of salt mist and acid-base, such as 72 hours. Then you can choose parylene plating, there will be a better guarantee.
Some people might confuse that why don’t recommend epoxy?
It cannot be guaranteed that nickel plated magnets and epoxy plated magnets can pass 72 hours salt spray test. That’s the reason why we only recommend parylene.
If you need 12 hours test for resisting salt spray, zinc plated is recommended to use. There are many kinds of zinc plating like white zinc, blue white zinc, blue zinc, color-zinc and black zinc. And now the salt spray test hours in the market is: white zinc can be tested for 16 hours, blue white zinc is 24hours, color-zinc is 48hours, black zinc is 12hours.
Generally nickel plated magnets can resist salt spray test for 48hours. The basic process of nickel plating is nickel - copper – nickel, which can ensure that magnets will not be damaged in case of corrosion.
These above introduce if nickel plated magnets can resist 72 hours salt spray test, and the suggestion of plating for salt spray test. Hope of any help to you.
