Most of the two types of magnets used by most enterprises and factories are mainly neodymium iron boron and ferrite. Some use the former more, and some use the latter more. Depending on the product application, the Xiamen everbeen magnet manufacturer will give you today. Nagging ferrite magnets.

      Ferrite arc magnet

      Ferrite magnet: Its main raw materials include BaFe12O19 and SrFe12O19. Manufactured by ceramic technology, the texture is relatively hard and it is a brittle material. Due to the good temperature resistance, low price and moderate performance of ferrite magnets, it has become the most widely used permanent magnet.

      Ferrite magnet is a sintered permanent magnet material composed of barium and strontium ferrite. In addition to strong anti-demagnetization performance, this kind of magnetic material also has the advantage of low cost. Ferrite magnets are hard and brittle, and require special machining processes. The heterosexual magnet is oriented along the manufacturing direction and must be magnetized in the direction taken, while the same magnet can be magnetized in any direction because it has no orientation, although a slightly stronger magnetic induction is often found on the side where the pressure is the smallest. 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 and speakers to toys and handicrafts, so they are currently the most widely used permanent magnet materials.

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

      What is the role of ferrite?

      1. Magnetic shielding, or absorbing electromagnetic waves.

      2. Isn't ferrite able to withstand high temperatures up to 450 degrees? The general ferrite can only reach 200 degrees.

      3. It has an adsorption effect, but the adsorption force is very small, and one group is conductive, and it is more used in motors.

      What is the density of ferrite?

      Sintered ferrite: density is about 4.9 g/cm3.

      Injection-molded ferrite with a density of about 3.8 g/cm3.

      Where are the most used ferrite magnets?

      Ferrite magnets are undoubtedly used most in various motors. Starter motors for motorcycles and cars, motors for opening sunroofs. Automatic curtain device, toy motor, etc.

      How much does it cost to open a ferrite mold?

      Our company currently has thousands of molds for round, ring, square and tile-shaped ferrite magnets. It can help customers save a lot of mold opening costs, usually about 30,000 to 30,000.
