Not long ago, a university student came to our carrich custom magnet and asked a lot of questions, but it can also be understood. One of the questions asked is about the thickness of the coating of NdFeB powerful magnet. What's the thickness of electroless nickel plating on magnet? How many μ? How much thicker than galvanizing?
What is the thickness of NdFeB nickel coating?
The thickness of NdFeB nickel plating is 10-20μm, and that of zinc plating is 5-10μm.
What is the thickness of other coatings?
For example, the thickness of gold plating is 10-15 μm, and that of epoxy coating is 10-30 μM.
