Super Strong permanent Sintered NdFeB Magnets

The NdFeB segments are use to Sensor, Motor, and LoudspeakerNdFeB N48 Features:

1) Superior magnetic properties than other magnets
2) Higher unit magnetic properties  
3) Smaller size and lighter weight in designing devices
4) Mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust, and elimination. Users should consider magnet coating, plating or suitable surface treatment
5) Less prone to chipping during handling
6) Lower temperature coefficient of magnetic properties than ceramic, higher than SmCo type rare earth magnet
7) Irreversible loss at high temperature
8) Types: N30, N33, N35, N38, N40, N42, N30M, N33M, N35M, N38M, N40M, N27H, N30H, N33H, N35H, N37H, N27SH, N30SH, N33SH, N35SH, N25UH,   N28UH, N30UH, N35SH, N38, N45, N48, and N50
9) High energy ranging from 8MGOe to 48MGOe with wonderful coercive force
10) Less expensive, and mechanically stronger and less brittle than SmCo
11) Density: 13%, smaller than SmCo products
12) For most applications, coating or plating is recommended
13) Advantages:
     a) High energy 
     b) Very high Hc and Hci output
     c) More economical than SmCo
     d) Wonderful performance at ambient temperature 
14) Disadvantages:
     a) Working temperature is below 2,000^oC
     b) Prone to oxidation than other magnet alloys
15) Widely used in apparatus and instruments where a strong magnetic field is needed,
including motors, sensors, microphones, electro-acoustics,  magnetic separation,
magnetic suckers and magnetic therapy

Company Profile

product name Super Strong permanent Sintered NdFeB Magnets

NdFeB Magnets Physical Properties:
1. Neodymium Magnets are the strongest magnets in the world., whose temperature resistance can reach 200 centigrade.
2. Neodymium Magnets are easy to machine, compared to Alnico and SmCo magnets.
Not so easy to be scrapped
3. Neodymium Magnets are with high resistance to demagnetization, which makes its property quite
Stable
