Product Description

Permanent Arc Ferrite Magnet

1. Product Introduction

Permanent Arc Ferrite Magnet: It is manufactured by ceramic process method. The texture is relatively hard and it is a brittle material. Because ferrite magnet has good temperature resistance, low price and moderate performance, it has become the most widely used permanent magnet.

Ferrite magnets are sintered permanent magnetic materials composed of barium and strontium iron. In addition to strong anti-demagnetization properties, this magnetic material has the advantage of low cost. Ferrite magnets are hard and brittle, requiring special machines

machining process. Because the magnets of the opposite sex are oriented along the manufacturing direction, they must be magnetized in the direction taken, while the magnets of the same sex can be magnetized in any direction because they are not oriented, although the pressure surface is often the smallest side.

Slightly stronger magnetic induction was found. The magnetic energy product ranges from 1.1MGOe to 4.0MGOe. Due to its low cost, ferrite magnets have a wide range of applications, from motors, speakers to toys and handicrafts.

It is the most widely used permanent magnet material.

Ferrite is divided into permanent ferrite, soft ferrite and microwave ferrite. Permanent magnet ferrites include barium ferrite and strontium ferrite. Soft ferrite is divided into manganese-zinc ferrite, nickel-zinc ferrite, magnesium-zinc ferrite, micro-

Wave ferrite includes yttrium ferrite and the like. There are also hexagonal ferrite and so on.
