Neodymium (NdFeB) MAGNETS

Neodymium permanent magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in shapes such as rings, blocks， discs ，arcs and etc .

Attributes of Neodymium

•    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
•    Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.

Applications of sintered NdFeB magnets

•    Automobiles
•    Medical equipments (MRI)
•    Magnetic separators
•    Linear actuators, acoustics
•    Servomotors, DC motors (automotive starters)
•    Computer rigid disc drives
•    And all other situations that need neo magnet’s high power output and high energy volume rate

Grades and physical properties of Sintered NdFeB magnets

There are a lot of grade from N series to AH series with different physical properties and Max.working tempertures ,which can meet different kinds of demands for your different magnet applications. For more information , please email to ms@xionghaimagnets.com

Magnetizing and Handling

Neodymium magnets are very brittle and very strong magnetically. Therefore, it is crucial to handle these magnets with extreme care to avoid personal injury and damage to the magnets. Fingers can be severely pinched between attracting magnets. Magnets can chip if allowed to “jump at” an attracting object. It is highly recommended that when constructing rare earth magnetic assemblies, they be magnetized after assembly.
