Products Description
1. About Neodymium Magnet
Neodymium magnet also referred as NdFeB magnet because they are composed primaryly of Nedymium (Nd), Iron (Fe), and Boron (B).Neodymium magnet can be classified to sintered Neodymium magnet, Bonded Neodymium magnet, and hot-pressed Neodymium magnet according to the detailed manufacturing process. Sintered Neodymium magnet still offers the strongest magnetic power nowadays and has been widely served to vast kinds of application, include high-performance permanent motors, brushless DC motors, magnetic separators, magnetic resonance imaging (MRI), sensors, loudspeakers, consumer electronics, and green energy.
2. Attributes of Neodymium Material
-- Very high resistance to demagnetization
-- High energy for size
-- Good in ambient temperature
-- Moderately priced
-- 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
3. Applications of Neodymium Magnets
-- Magnetic separators-- Linear actuators
-- Microphone assemblies
-- Servo motors
-- DC motors (automotive starters)
-- Computer rigid disc drives, printers and speakers

Typical Magnetic Properties
Typical Platings/Coatings
Plating neodymium magnets is an important process to protect the magnet against corrosion.
The typical coating for a neodymium magnet is Ni-Cu-Ni coating.
Some other options for coating are zinc, tin, copper, epoxy, silver, gold and more.
Inspection Capabilities
Finite Element Analysis (FEM) Service
Finite element analysis (FEA) is a very effective tool to obtain relatively reliable results before building a prototype. FEA can simulate customer’s most demanding engineering challenges on the early stage of development, including magnetic field strength, attractive force, torque, and many more parameters.
