Ring Shaped Ndfeb Magnet

NdFeB magnets  are very fragile sintered materials.  especially small size sintered ndfeb. And manufacturers often produce big size workblank, when order comes. It is easy and fast to cut them to customers' demands. NdFeB Magnets are formed by Neodymium, Iron,Boron, Dy Ga and Pr, and, because it is  pressing type, the sintered ndfeb do not need plasticizer to form  shapes. Magnet cuntersunk technique need careful and adept workers operated with patience, so the unit price will much higher than rectangle block type. After cuntersunk process, magnets will be very easy to add screw on it and that will offer more stablity on fixed positions,and it will be very convinient to add metal hook or loop unit on it. Plating (Coating) processes is very meticulous,because it very sensitive to temperature and acid,Very easy to crack when meet sharp temperature change and easy to melt in strong acid liquids. That is why plating ndfeb material only can be proces…
