1.super strong Br resident induction
2.excellent demagnetization resistance capability
3.good price relative to its high magne
1.Magnet
NdFeB magnet features:
Sintered NdFeB magnet is one of the high performance rare earth permanent magnets,which use neodymium(Nd),iron(Fe),and boron(B) as their main ingredients and is susceptible to demgnetization when exposed to elevated temperatures.
There are many grades which can withstand high temperatures,by dictating the performance of the Neodymium magnet,There are sintered NdFeB,sintered AINiCo,sintered SmCo and sintered Ferrite.
2.Surface Treatment Method:
Metallic Zinc,Nickel,Nickel+Nickel,Copper+Nickel,Nickel+Copper+Nickel
Temporary Surface:Passivation
Dimension are Available Attributes of Neodymium Magnets:
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 for heat materials are being introduced perio.
3.Applications of Neodymium Magnets
Magnetic separators
Microphone assemblies
DC motors(automotive starters)and other motors
Computer rigid disc drives
Magnetic resonance imaging
Various holders
