What Is The Most Used Ferrite Magnet?

Most of the enterprise factory with the magnet or NdFeB mostly ferrite with less, but can not be generalized, specifically to see the product application, today the magnet manufacturers to come to everyone nagging nagging ferrite magnet.

Ferrite Magnet: Its main raw materials include BaFe12O19 and SrFe12O19. Made of ceramic technology, the texture is relatively hard, is a brittle material, because the ferrite magnet have good temperature resistance, low price, moderate performance, has become the most widely used permanent magnet.

Ferrite magnet 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 magnet 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 magnet have a wide range of applications, from motors, speakers to toys, handicrafts, and thus is currently the most widely used permanent magnet materials.

Ferrite sub - ferrite, soft ferrite, microwave ferrite. Permanent ferrite has barium ferrite, strontium ferrite. Soft ferrite is divided into manganese zinc ferrite, nickel zinc ferrite, magnesium zinc ferrite, microwave ferrite yttrium ferrite and so on. There are hexagonal ferrite and so on.

What is the effect of ferrite?

1, magnetic shielding effect, or absorb electromagnetic waves.

2, ferrite is not the highest high temperature to 450 degrees? General ferrite can only reach 200 degrees.

3, there is adsorption, but the adsorption force is very small, a gang is a conductive effect, in the motor with more.

What is the density of ferrite?

Sintered ferrite: Density of about 4.9 g / cm3.

Injection ferrite, the density of about 3.8 g / cm3.

Ferrite magnet used most is undoubtedly a variety of motors. Motorcycle and car start motor, car window sunroof open motor. Curtains automatic devices, toys, motor and so on.
