Product Description
The coercive force of Sintered NdFeB is very high and its Bhmax is about ten times of that of Ferrite magnet. It can support about 640 times of its weight. As its fairly good mechanical properties, it can be processed into many different shapes or with various holes. Some of its products with high-perfomance can work under the situation up to 200. However, it is easy to be rusted for its elements.Therefore we should make surface treatment in terms with different requirements, such as zinc-coated,Nickel-coated,Ag-coated,Au-coated,Epoxy-coated etc.
At present we can manufacture the sintered NdFeB in a range of physical grades like following table. And we can realize different shapes such as disc magnets, ring magnes,rectangle magnets, arc segment magnets and some other special shaped magnets.

Physical properties of Sintered NdFeB Magnets.
Surface Treatment
The corrosion resistance of NdFeB is considered poor. Painting, coating, or plating is therefore highly recommended for neodymium magnets for sale. Plating NdFeB is a difficult process, and commercial plating plants are unlikely to be able to achieve plating with good adhesion. Nickel, Zinc, or Tin plating provides good corrosion resistance for NdFeB magnets. We are also able to make cadmium chromate or aluminum chromate as NdFeB coating by using vacuum deposition techniques. A variety of organic coatings have also been successfully developed for NdFeB, exhibiting good corrosion resistance characteristics. Especially in harsh environments, it may be advisable to use a combination of coating techniques, or to encapsulate the material in a sealed housing.

Magnetizing and Handling
All neodymium magnets for sale require extremely high magnetizing fields and special consideration must be given to this when designing complex assemblies, if it is intended to magnetize after assembly. We will recommand right magnetic direction for you in accord with your requirements.
Rare Earth materials are mechanically weak, and magnetically very strong. They must therefore be handled very carefully to avoid damage and injury during personnel handling the magnets. Receiving and assembly personnel should be warned about the of handling magnetized Rare Earth magnets.
