This is a kind of galvanized NdFeB magnetic ring with an outer diameter of 58mm. 58mm is not big, but it is really a big size for Neodymium magnet, because most customers' demand is 10-20mm. The larger the size, the higher the price. Unless we have to use larger mechanical equipment, heavy industry, experiments, etc., if you need 58, 68, 78, 88mm or larger ring rare earth Neodymium magnet, our company can process them.
