The most used rare earth neodymium magnet coatings on the market are zinc or nickel-copper-nickel. Today, I will introduce a magnet coating with better salt spray resistance - black epoxy coating.
The black epoxy coating is nickel-plated on the iron-iron-boron magnet, and then a layer of resin paint is added on the outside. The epoxy resin electrophoresis is divided into metal electroplating layer (nickel/copper) primer + epoxy resin electrophoresis layer and directly on the magnet base. Epoxy plated.
Features of NdFeB (Neodymium) magnets with black epoxy plating:
High temperature resistance 380 ℃. (Temperature resistance of non-magnets)
Solvent resistance
A variety of colors are available, we usually see black epoxy, in fact, there are other colors, but not common, such as gray, red and other colors.
No hanging point
Salt spray resistance 72H
Plating thickness 15-25um
Application of NdFeB magnet with black epoxy coating:
Elevator motor, compressor, stepper motor, brushless motor, DC motor, starter motor, DVD spindle motor, optical disc drive.

You are now seeing the specifications of this magnet ring OD 13mm, bore diameter 8mm, thickness of 3.5mm, the surface of the black epoxy, due to the reason of the photo may look like a ferrite, the actual bonded ring magnets, suitable for a variety of types of motor, sensor, and electric appliances....
Neodymium iron boron is divided into sintering, bonding and injection molding according to the different production processes. The general neodymium arc magnet is sintered, also called sintered arc neodymium magnet. Today this product is a bonded arc magnet that is not much used. The difference between sintered arc magnets is that bonded NdFeB magnet tiles require molds to produce....
