block ferrite magnet

Description:

A low cost alternative to other magnetic materials, offers relatively high operating temperatures and good resistance to corrosion. However, it has lower energy levels (Br) and is brittle in nature.

The most inexpensive, chemical stability is good, Br is low,negative temperature easy to get aging.

Compared with isotropic ferrite magnet, (BH)max is about three times as much as isotropic ferrite magnet.

And in the manufacture craft in relative a little bit more simple.

Application: widly applies in the automobile electrical machinery (wipers,sit chair motor ), teaching, doorabsorber, magnetic bike anf massage chair, etc.
