    Neodymium Magnets

    Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. Neodymium magnets’ popularity has grown rapidly due to their high Maximum Energy Product and their wide range of available shapes, sizes, and grades.

    Neodymium magnets can be manufactured by sintering, compression bonding.

    Plating /Coating

    The Neodymium magnet is easy corrosive, so its surface is usually treated with some special methods. Nickel is the most common and usually preferred to protect the magnet from corrosion. Our Nickel plated magnets are actually tripled plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel plated magnets. Some other options for coating are Zinc, Tin, Silver, Gold plating, Phosphor and Spray Epoxy Resin .

    Applications of Neodymium Magnets

    Linear Actuators

    Microphone Assemblies

    DC Motors(Automotive starter)

    Servo Motors

    Magnetic Separators

    Computer rigid disc drivers,printers and speakers

    Attributes of NdFeB Material

    Very high resistance to demagnetization

    High energy for size

    Good in ambient temperature

    Moderately priced

    Material is corrosive and should be coated for long term maximum energy output
