OEM/ODM China Neodymium Speaker Magnets - Ring Neodymium Magnets with Nickle Plating – Meiko

Neodymium Ring Magnet with NiCuNi Coating are the disc magnets or cylinder magnets with centered straight hole. It’s widely applied for motors assemblies, economics, like plastic mounting parts for providing constant magnetic force, due to the characteristic of permanent rare earth magnets. Such electronic magnet processes higher magnetic performance than Hard Ferrite used in electronic magnets with much smaller size.Meanwhile,this kind of neo magnet has advantage of high precision,which can improve the electronics performance. Sintered Neodymium(NdFeB) magnets are the most advanced commercialized permanent magnet materials today.

The N pole is marked with red line for workers’ easy assembling, no more attention to paid on the poles of magnet, which side is N, which side is S pole, as the wrong pole installing in the processing will cause the assembling components can’t work.
