Sintered Neodymium-Iron-Boron (NdFeB) magnets, also known as “Neo” magnets, offer the strongest magnetic power today. They are particularly suitable for high volume production with variety of shapes and sizes. Precise dimensional control can be achieved in machining processes.
With these advantages, Neo magnets have been widely used in lots of commercial fields. Such as high performance motors, brushless DC motors, magnetic separators, magnetic resonance imaging (MRI), sensors and loudspeakers.

Characteristics of N28EH Neodymium-Iron-Boron Ring Magnet

Neodymium magnet is currently the strongest one available, best in magnetic performance
and energy.
NdFeB magnet have the characteristics of:

Extreme strong Br residual induction
Very high energy product
Excellent demagnetization resistance capacibility
Coating is needed for NdFeB Magnet which is not suitable for high temperature working condition.
High Coercive Force
Very hight energy products
Low corrosion resistance (when uncoated)
Low mechanical strength – Brittle

Strongest magnetic power
Hight coercive force
Brittle & Hard
Good temperature stability
High resistance to demagnetization
Excellent performance and cost ratio

Some common applications custom include:
Arc magnets
Motor magnets
High temperature magnets
Rubber Strip Magnet
Adhesive magnets
Molded magnets
