Neodymium iron boron(Nd2Fe14B)is another 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 magnets.

NdFeB material is more costly by weight than ceramic or alnico but produces the highest amout of flux per unit of volume or mass making it very economical for many applications.their high energy products lend themselves to compact designs that result in innovative applications and lower manufacturing costs.

Unprotected NdFeB magnets are subject to corrosion.Surface treatments have been developed that allow them to be used in most application.These treatments include copper,silver.gold,nickel,zinc and tin plating and epoxy resin coating and more good treatments now.
