Buyer Guide:

In order to quote you the best price quickly, please provide the following information:
1. Product size, grade, coationg etc
2. Order quantity
3. Attached the drawing if customized
4. Any special packing or other requirement


Advantages:

1) Strong power magnet
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) 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.



Safety Warning:

1. Make sure keep the magnets are out of reach children and pets, it is not a TOY, and small magnets will pose a choking hazard.
2. Watch your fingers, as they are very strong magnets, which are difficult to pull apart and fly together quickly from far away. So it is very easy to pinch fingers between attraching poles.
3. Keep the magnets far away from medical devices, electronic products, and magnetic media, as our magnets have strong magnetic fields which may affect and/or disrupt the functioning of these 
medical devices,electronic products,and magnetic media.
4. Magnets are fragile, they can crack, chip, or shatter if allowed to slam against each other. so make sure handle with care, eye protection glasses should be worn when handling magnets, due to launching of small magnetic pieces at high speeds if shattering occurs.
