Neodymium Block Magnets are usually from the bigger semi-finished blocks that will be cut to suitable sizes and then will be milled the surface and finally will be coated with Nickel(Ni-Cu-Ni), Black Nickel, Zinc(Trivalent), Epoxy, Stannum, Gold, Silver or Parylene etc to resist rust. The biggest block for ordinary grade N35 we make now is 250 x180x50mm, magnetized through 50mm that is almost the maximum size that we can magnetize through in our industry. The application for NdFeB Block magnets are limitless and some are widely used in MRI and linear motors and all kinds of magnetic seperation systems.
