We can provide magnets in Neodymium Iron Boron, SmCo, Alnico, or any other magnetic material, and offer coatings and platings that are biocompatible, including Parylene, and Titanium cases.

One of our most technologically sophisticated magnets is a Micro-Magnet designed for a medical application.  This magnet is offered in Neodymium Iron Boron with energy products up to 52 MGOe, and coated with an inert biocompatible protective coating.
