Introduction of ferrite properties and function

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

      The ferrite magnet is a sintered permanent magnet material composed of tantalum and niobium iron. In addition to strong anti-demagnetization properties, this magnetic material has the advantage of low cost. Ferrite magnets are rigid and brittle and require special machining processes. The opposite-sense magnets are oriented in the manufacturing direction and must be magnetized in the direction taken, while their isotropic magnets can be magnetized in any direction because they are not oriented, although a slightly stronger magnetic induction is found on the smallest side of the pressure-receiving surface. The magnetic energy product ranges from 1.1 MGOe to 4.0 MGOe. Due to its low cost, ferrite magnets have a wide range of applications, from motors and speakers to toys and crafts, making them the most widely used permanent magnet materials.


      What is the function of ferrite?

      1. Magnetic shielding or absorbing electromagnetic waves.

      2. Is ferrite not able to withstand temperatures up to 450 degrees? The average ferrite can only reach 200 degrees.

      3, there is adsorption, but the adsorption is very small, a group of them are conductive, more in the use of motors.


      What is the density of ferrite?

      Sintered ferrite: density of about 4.9 g / cm3.

      Injection molded ferrite with a density of about 3.8 g/cc.


      Where are the most used ferrite magnets?

      The most used ferrite magnets are undoubtedly various motors. Starter motor for motorcycles and cars, motors with sunroofs for car windows. Curtain automatic device, toy motor, etc.
