Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.
NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.
The 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, silver, gold, etc., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.
Pic shows the magnet with Zn coating and the grade is UH,it means max working temperature is 180 degree.
