NEODYMIUM-IRON-BORON MAGNETS (Rare earth permanent magnetic). Sintered neodymium-iron-boron (NdFeB) magnets, They
offer the highest energy product of any material today and are
available in a very wide range of shapes, sizes and
grades.
MAXIMUM USE TEMPERATURE AND CORROSION The
temperature stability and resist corrosion is not as good as
permanent ferrite magnet.

Remark:
??magnetic conductivity??rec-1.05, Currie Temperature Tc=310??
??The above magnetic parameters and physical features are measured at room temperature. The sample is D10??10 inspection figures.
??The highest service temperature relies on the length width ratio and environmental factors. The magnetic flux is less or equal to 5% at such temperature??
