Sintered Neodymium Magnets – Real Power…
Sintered neodymium iron-boron (NdFeB) magnets are the most powerful commercially available magnets in the world. With energy products between 26 and 52 MGOe, they are the perfect solution to a host of magnetic applications demanding very strong, highly coercive magnets that are available in large quantities at a relatively low cost.
Due to their impressive properties, their small size relative to their strength, and the abundance of raw materials available, NdFeB magnets are increasingly replacing those made from older materials such as ceramic and alnico, as well as other rare-earth materials such as samarium cobalt.
NdFeB magnets contain iron and are very susceptible to corrosion. If they are to be exposed to moisture or corrosive elements of any kind, coating or plating is highly recommended. NdFeB magnets exhibit moderate mechanical properties, and are not excessively brittle, however they will crack or chip if dropped or allowed to snap together carelessly.

Characteristics of Neodymium Magnet Ring Epoxy Black

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
