Neodymium ring magnet ais also known as tube magnet, a round disc magnet with a straight hole along the centre, the hole in centre ensures great versatility. sintered neodymium magnetic ring
Most ring magnet is with north and south poles on the flat circular surfaces (this is called as axial magnetisation). The few exception that is diametrically magnetised is specifically marked. Also, Multi pole ring magnet, even radially magnetized ring magnet, is more and more referred in this industry now.

Technology We have advanced R&D center,quality control and professional machining technicians.
Neodymium magnet raw magnetrials are widely used in industrial field,such as speaker,louder speaker,sensor,motor,alternator ect;And also it is popular in ladies bags,purses,shoes,crafts and jewelry ect.
NdFeB magnets are available in sintered as well as bonded forms. The bonded form need almost no machining yet tolerance is small, The flux of the bonded form is up to 10 MGOe while sintered form available to reach 52 MGOe. The sintered form usually requires some finishing operations in order to suit mechanical tolerances.
Plating NdFeB is a difficult process, coating,acidification,passivation each process should be acidity soft and temperature friendly. Zinc, Nickel, NiCuNi and Epoxy plating providegood corrosion resistance and nice appearance for NdFeB magnets.
