Sintered NdFeB Magnet is one of the high performance rare earth permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as their main ingredients and is susceptible to demagnetization when exposed to elevated temperatures. There are many grades which can withstand high temperatures, but several factors will dictate the performance of the Neodymium magnet. There are Sintered NdFeB, Sintered AlNiCo, Sintered SmCo and Sintered Ferrite. Multipole Diametrically Ring NdFeB Magnets
NdFeB magnets, have the characteristics of :
Super strong Br Resident induction.Excellent demagnetization resistance capability.
Good Price relative to its high magnetic properties.
Coating is needed for Multi-Pole Radial Ring Neodymium-Iron-Boron Magnet
Strong Neodymium Ring Magnets N35, N38, N42, N45, N50 & N52. Neodymium Ring Magnets are widely used in such applications as holding, motors, consumer electronics, medical, sensors and speakers. Due to the high magnetic strength of a Rare Earth Magnet, it has replaced other magnetic materials in order to make a design smaller but achieve the same result.

Through the Thickness: Ring magnets where a magnetic field travels from the ID of the ring magnet to the OD of the ring magnet. Diametrically Ring Magnets
Radially Magnetized: Radially magnetized ring magnets have the magnetic poles on the OD / ID instead of the face. Radial magnets are made as a single piece or in multiple pieces depending upon the size of the magnet. A list of radial rings is available under our Radial Ring magnet section.
