Ferrite Magnets Overview And Characteristics

Overview of ferrite magnets and features do you know?

The ferrite magnet is a permanent magnet made of SrO or BaO and Fe2O3 as raw materials. Early development by the gifted magnetic company, compared with other permanent magnet, ferrite magnets hard and brittle, low magnetic energy. But it is not easy to demagnetize the corrosion is not easy, the production process is simple and inexpensive, therefore, in the entire magnet industry, the highest production of ferrite magnets and is widely used in industrial production.

Ferrite magnets Overview

Ferrite magnets are sintered permanent magnetic materials, composed of barium and strontium iron body, this kind of magnetic material in addition to a strong anti-demagnetization performance, there are advantages of low cost. Ferrite magnets are rigid and brittle and require special machining processes. The opposite magnets are magnetized in the direction taken in the direction of their manufacturing direction, and their homogeneous magnets can be magnetized in any direction because they are not oriented, although a slightly stronger magnetic induction is found on the side where the compression surface is often the smallest. The magnetic energy product ranges from 1.1MGOe to 4.0MGOe. Due to the low cost, ferrite magnets have a wide range of applications, from motors, speakers to toys, handicrafts, and thus is currently the most widely used permanent magnet materials.

Ferrite magnets Features

Using powder metallurgy method of production, residual magnetization is low, the magnetic permeability is small. Coercive force is strong, strong anti-demagnetization ability, especially suitable for dynamic working conditions of the magnetic circuit structure. The material is hard and brittle and can be used for cutting tools with emery tools. The main raw material is oxide, it is not easy to corrosion. Operating temperature: -40 ° C to + 200 ° C.

Ferrite magnets are divided into the opposite sex (heterosexual) and the same sex (isotropic). The isotropic sintered ferrite permanent magnet material has a weak magnetic properties but can be magnetized in different directions of the magnet. The anisotropic sintered ferrite permanent magnet material has strong magnetic properties but can only follow the magnet Fixed magnetization direction.
