Neodymium Magnets also know as Neo, NdFeB magnets, Neodymium Iron Boron or Sintered Neodymium, are the strongest commercially available rare earth permanent magnets. These magnets offer the highest energy product and available to be manufactured in a wide range of shape, sizes and grades including GBD. The magnets can be plated with different coating to protect from corrosion. Neo magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
This popular cube magnet has been used in a wide range of applications and is known for its incredible strength despite its small size. Cube magnets are used in a variety of applications, including medical magnets, sensor magnets, robotics magnets, and halbach magnets. Cube magnets generate uniform magnetic fields all around them. Here are a few examples: Stud finder, science projects and experiments, magnetic pick-up tool, home improvement, and DIY projects are just a few examples.

Because of their corrosive nature, neo magnets have some limitations. A protective coating is highly recommended in humid applications. Epoxy coating, nickel plating, zinc coating, and combinations of these coatings have all been used successfully. We also have the ability to coat neodymium magnets with Parylene or Everlube. The coating’s effectiveness is determined by the quality of the base material. Select the best plating for your products!
