It not only has the characteristics of high remanence, high coercivity, high magnetic energy product, high performance-to-price ratio, but also is easy to be processed into various sizes. Now it has been widely applied in various fields. Especially suitable for the development of high-performance, miniaturized, lightweight alternative products.Different Types    A.Disc with Countersink                                                                                     B.Double CountersinkC.Straight Countersink                                                                                        D.
