Neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from neodymium,iron,boron and same other trasitive metallic elements to make it strong.

Disc Neodymium Magnets (Neo disc / disk), are the perfect marriage of small size and maximum power or strength. Ningbo Bestway Magnet provides a large variety of Neodymium disc magnets in a variety sizes and with several coatings such as Nickel, zinc or Gold for protection against corrosion.
This type of permanent magnet can be used for different applications such as: metal separation, magnetic therapy, brochure closures, school science experiments, jewellery-making, packaging, book-binding and POS displays to engineering applications.
With a diameter greater than the thickness, our rare earth disc magnets provide a very strong magnetic field and a high coercivity. Excellent value for money ensures that Neodymium discs are among the most widely bought and sold of commercially available magnets.
Neodymium-Iron-Boron magnets display superior magnetic properties, with a higher unit magnetic field density, assuring a more compact and lighter weight in designing devices. However, being mostly an iron based alloy, Neo magnets are susceptible to surface oxidation or rust. To eliminate this susceptibility, the magnet is coated, plated or another suitable surface treatment applied. Neo magnets however do not perform well under high temperatures, unless the non standard high temperature grades are specified.
Chemical composition: Nd2 Fe14 B
Hard and brittle
Excellent resistance to demagnetisation
Poor resistance to corrosion
Good temperature stability
High performance material provides excellent cost to performance
