- Magnetic Grade
When magnetic grade is higher, the magnetic performance is stronger.
N35: N means NdFeB; 35 means the maximium magnetic energy product. There is no number besides the 35. That means the max. working temperature is 176°F.
N42SH:N means NdFeB; 42 means the maximium magnetic energy product. SH is the high temperature resistance magnetic grade. It means that the maximum temperature is 302°F.
N grade means the maximum temperature is 176°F.
M grade means the maximum temperature is 212°F.
H grade means the maximum temperature is 248°F.
SH grade means the maximum temperature is 302°F.
SH-T grade means the maximum temperature is 320°F.
UH grade means the maximum temperature is 356°F.
UH-T grade means the maximum temperature is 374°F.
EH grade means the maximum temperature is 392°F.
AH grade means the maximum temperature is 428°F.
- Magnetic Performance List

- Performance Parameter
Br:the permanent magnet is magnized to technology saturation. After removing the external magnetic field, the remaining Br is the residual magnetic flux density.
Hc:The opposite force of the permanent magnet which is magnized to technology saturation makes the residual magnetic flux density to be zero.
BH:It means the magnetic energy density between the magnetic space.
