NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.

Neodymium Iron Boron square magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.

Neodymium Iron Boron square magnet's advantage is high cost-effective, with good mechanical properties, easy cutting; according customer's demand to manufacture in a wide range of shapes, sizes and grades.

The shortcoming is easy to rust, oxidation, so the Sintered NdFeB's surface is usually required for plating such as zinc, nickel, copper,silver, gold, etc., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.

the stability of the time: the place of limitation caused by room temperature for a long time, the coercive force of it and the materials used by the permanent magnet and the magnet size ratio, the higher the coercivity, size ratio, itmore stable. During use to maintain the stability of the exchange forced demagnetization method can obtain good results.

Pic shows the magnet with NiCuNi coating and the grade is UH,it means max working temperature is 180 degree.
