Product Description

product name :Permanent NdFeB irregular shape, used in motor

The main raw material of the NdFeB permanent magnets are the rare earth metal neodymium (Nd) 32%, the metal elements iron (Fe) 64% and non-metallic elements boron (B) 1% , adding a small amount of dysprosium (Dy), terbium (Tb), cobalt(Co), Niobium (Nb), gallium (Ga), aluminum (Al), copper (Cu) and the like elements. NdFeB ternary compounds is based on the Nd2Fe14B, its composition should be similar with Nd2Fe14B Formula.

It is have three main parameters: First, Br (Residual Induction), GAUSS of units, which is the residual magnetic flux density when the magnetic field is removed from saturation, representing the external magnetic field strength which it can provide; Second, Hc (Coercive Force), Oersteds of units, Putting the magnet on a reverse magnetic field, its properties will disappear when the applied magnetic field is increased to a certain intensity, the ability to resist the applied magnetic field is known as the coercive force, represents the ability to measure the resistance to demagnetization; Third, BHmax, Gauss-Oersteds of units, which is the magnetic energy from the unit volume of material, it is a physical quantity.
