Neodymium iron boron ( NdFeB) is a type of rare earth magnetic material. 
NdFeB is the most advanced commercialized permanent magnet material available today.
This material has similar properties as the samarium cobalt except that it is more easily oxidized
 
and generally doesn't have the same temperature resistance.
However, NdFeB magnets have the highest energy products approaching 52MGOe and 
are
 mechanically stronger than samarium cobalt magents. NdFeB material is more costly by weight
 than
 ceramic or alnico but produces the highest amount of flux per unit of volume or mass amking 
it very economical for many applicantions. Their high energy products lend themselves to comnpact designs

that result in innovative applications and lower manufacturing costs.
Unprotected NdFeB magnets are subject to corronsion. Surface treatments has ben developed
that
 allow them to be used in most applications. These treatments include copper, silver,, gold, nickel,zinc
and tin plating and epoxy resin coating.

Beneficial characteristics of NdFeB magnets include their very high energy product, very high coercive force, 
and moderate temperature stability. Drawbacks include lower mechanical strength
,and low corrosion resistance 
when not properly coated or plated
