Neodymium, Iron, Boron and a few transition metals. They have high remanence, high coercive force, high energy product, and high performance /cost. Currently NdFeB magnets are the strongest magnets available in the world.
Machining and Tolerances
Generally, NdFeB magnets must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on NdFeB materials using carbide tools, but surface finishes thus obtained may be less than optimal. The Standard tolerances for NdFeB magnets are +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required.
Magnetization
NdFeB magnets require extremely high magnetizing fields, and can be magnetized in any direction as long as it is aligned properly. In some instances multiple pole magnetization is possible with special fixtures. All NdFeB magnets are anisotropic, and can only be magnetized in the orientation direction, so particular consideration must be given to this when designing complex assemblies, if it is intended to magnetize after assembly.
Surface Treatment
The corrosion resistance of NdFeB magnets is considered poor. Surface coating or plating is therefore highly recommended for NdFeB magnets. All kinds of surface coating are available, like Nickel, Zn, Ni-Cu-Ni, Gold, Silver, Sn, Chrome. We also applied special surface protection to NdFeB magnets, like ABS coating, Rubber coating, PTFE(Teflon) coating, stainless steel case, etc.
Packing
NdFeB magnets are mechanically weak, and magnetically very strong. They should be packed properly in order to help user to use and handle them.
