The irregular Neodymium magnets are relatively difficult to machine because Neodymium magnets are too brittle when you machine them but we can do many complicated shapes of neodymium magnets according to customer's special requirement and this kind of magnets are usually used in some new developed electronic components and craft products.
There usually need many machining processes such as cutting, wire cutting, drilling, milling and turning etc and the cost is relative higher than ordinary shapes of magnets. The coatings are still Nickel(Ni-Cu-Ni), Black Nickel, Zinc(Trivalent), Epoxy, Stannum, Gold, Silver or Parylene etc in order to keep from rusting according to order requirement.
