NdFeB

Sintered magnet: it is a kind of high-performance rare earth permanent magnet material with neodymium (nd), iron (FE) and boron (b) as the main components. It is easy to demagnetize at high temperature. There are many grades that can withstand high temperatures, but there are several factors that will determine the performance of neodymium magnets. There are sintered NdFeB, sintered alnico, sintered SmCo and sintered ferrite.

NdFeB magnet has the following characteristics:

Strong br resident induction, excellent anti demagnetization ability.

Compared with its high magnetic performance, the price is good.

NdFeB needs coating

Surface treatment method: type information

Metal zinc, nickel + nickel, copper + nickel, nickel + copper + nickel,

Gold, organic epoxy, nickel + epoxy coating

Temporary surfaces: passivation
