Neodymium Iron Boron (NdFeB) magnets, of the Rare Earth class, have been commercially available since the mid -1980's. Their popularity has grown rapidly due to their high Maximum Energy Product and their wide range of available shapes, sizes, and grades.
NdFeB magnets can be manufactured by sintering, compression bonding, injection molding, and extrusion. The sintered form holds the highest energy product of up to 48MGOe, while the bonded form holds a lower energy product of up to 10MGOe. The majority of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction. In general, magnetizing fields of approximately 30KOe are required to saturate NdFeB magnets.
These magnets are prone to corrosion in humid environments. For this, liquid epoxy, dry epoxy, nickel plating, zinc plating, and combinations of these coatings may be used as a protective measure.
Surface Treatment Method:
Zinc,Nickel,Tin,Phosphor,Silver or Gold Plating Spray Coating Epoxy Resin.
