The round magnets with a hole in the center are made of SrO or BaO and Fe2O3 by molding and sintering, they are looks like discs and known as ring-shaped permanent ferrite(ceramic) magnets. Ring shape ferrite (ceramic) magnets are axially magnetized, and with magnetic poles on flat surface. Ring-shaped permanent ferrite magnets are carried with anisotropic properties and wide size range from small to large. Characteristics Of Ferrite Ring Magnets Magnetic ferrite ring have excellent corrosion resistance and can be used without electroplating Ferrite ring magnets are very hard and brittle, easy to break and difficult to process. The permanent ferrite rings has very good temperature resistance, with relative magnetic stability up to 250 degrees Celsius. Ferrite ring magnets have greater coercivity and strong resistance to demagnetization. Application Of Permanent Ferrite Magnet Rings Ferrite magnet rings (also known as ceramic magnet rings) have less energy than other permanent magnet rings, but advantages of resistance to demagnetism, corrosion resistance, and low cost make them a popular choice for many projects. Ferrite ring magnets of various sizes are often used in loudspeakers, household appliances, torque drivers and resonance imaging. Holding, closing doors, joinery and lighting fixtures are other applications of permanent ferrite rings.

This is a kind of permanent magnet made of SrO or Bao and Fe2O3 as raw materials by sintering. It is called china ferrite magnets. Because its process is similar to that of ceramics, it is also called ceramic permanent magnet. Ferrite materials are very brittle and require special processing techniques to produce specific shapes and sizes. According to the magnetization characteristics, ferrite(ceramic)magnets can be divided into anisotropic ferrite and isotropic ferrite.That must be magnetized in a preset direction are anisotropic ferrite magnets, while that can be magnetized in any direction are isotropic ferrite magnets. The magnetic force of isotropic ferrite is weaker than that of anisotropic ferrite. We mainly supply industrial anisotropic hard ferrite magnets. Features & Advantages Of Ferrite (Ceramic) Magnets Ferrite (ceramic magnets) magnet has strong anti demagnetization performance, and can be used normally at temperatures up to 250 ℃ without demagnetization. The original production of ferrite is relatively low, mainly because the raw materials are cheap and the production method is simple. Ferrite(ceramic) magnet is the cheapest hard industrial magnet with the largest output. wholesale ferrite magnet has strong corrosion resistance, because its raw material is oxide, it can resist the chemical corrosion of many dilute acids, alkaline solutions, organic solvents and some hydroxides without electroplating coating. Ferrite (ceramic) magnet has medium strength magnetic force, its magnetic energy product range is 1.1MGOe to 4.0MGOe, and its magnetic force is between soft magnet and rare earth magnet.

The flat circular hard magnets made out through molding and sintering with raw material of SrO or BaO and Fe2O3 called sintered ferrite (ceramic) disc magnet, its surface is in black color. The round shape is one of the most common shapes of ferrite magnets, which has a narrow range of magnetic energy product. The magnetic energy product of different grades sintered ferrite disc magnets vary from 1.1MGOe to 40 MGOe. Permanent ferrite (ceramic) disc magnets are applied in household appliances, magnetic separation, crafts and so on. Characteristics Of ceramic disc magnets Ferrite(ceramic) discs are not corroded easily, because the main raw material is oxide, so surface coating treatment is no longer needed. Ferrite(ceramic) magnet discs are produced by powder metallurgy method, they have low remanence, recovery of magnetic permeability is small, compared with other permanent magnet discs, round ferrite disc magnets are hard and brittle, have high coercivity, not easy to demagnetization, and low price, is the cheapest round type permanent magnet. Property&Grade Of Ferrite Disc Magnets ceramic disk magnets are divided into anisotropy (allotropy) and isotropy (isotropy). The magnetic properties of isotropic sintered ferrite disc magnet have weak strength, but they can be magnetized in different directions of magnets. The common properties of isotropic disc ferrite magnets are Y8T and Y10T. The anisotropic sintered ferrite disc magnets have strong magnetic properties, but they can only be magnetized along the predetermined magnetizing direction of the magnet. Common grades of the anisotropic disc ferrite magnets are Y25, Y30, Y35, Y30BH.

Ferrite magnet blocks are rectangle (or square) permanent magnets made of basic raw material of SrO or BaO and Fe2O3 based by molding and sintering. Smaller ferrite block magnets can also be processed by cutting. The magnetic energy product of the rectangular ceramic block magnets is low, It ranges from 1.1MGOe to 40 MGOe, depending on the grade. Because the main raw material is oxide, so the ferrite block magnets are not easy to corrode. Advantages&Application Of Ferrite Blocks Magnets Compared with other rectangular permanent magnet, ferrite rectangular magnet block is hard and brittle, low magnetic energy, but its production process is simple, not easy to demagnetize, not easy to corrosion, and low price. Therefore, in the whole industrial permanent magnet, the output of ferrite rectangular block magnet is the highest, the larger size of the ferrite block magnets can be used in magnetic separation applications, the smaller size of the square ferrite magnets are often used in arts and crafts, toys, magnetic adsorption.

Ferrite arc magnet is a kind of functional electronic component, called motor magnet, which is mainly used in DC micro motor. The magnetic properties of ferrite motor magnets tile show that they have high permeability at high frequency. In addition to the magnetic properties, dimensional tolerances and appearance of the permanent ferrite arc (segment) magnets meets the national standards and user needs. Another important criterion is mechanical strength. If the mechanical strength is not enough, the ferrite motor magnets will break during the installation and use, resulting in the scrapping of the motor. Generally, ferrite magnets used for small motors where there is no requirement for power density and torque density, such as water pump motor Characteristics of Arc Ferrite Magnet The arc(ferrite segment magnets) shaped permanent magnets mainly made of SrO or Bao and Fe2O3 by sintering, which seems to be part of the ring magnets, are called ferrite arc/segment/tile magnets. Ferrite arc(segment) have the characteristics of low magnetic energy, not easy to corrode and not easy to demagnetize. In the whole permanent magnet industry, arc(segment) shaped ferrite magnets are the most important industrial magnets for various motors. Production Process Of Ferrite Tile Magnets The production process of sintered ferrite(ceramic) tile magnets are mainly divided into wet pressing anisotropic, dry pressing isotropic and dry pressing anisotropic. The difference between the isotropic and the anisotropic lies in whether there is orientation magnetic field during the pressing. Here, the process of anisotropic wet pressing is mainly introduced. Wet compression process is: raw material - presintering - coarse crushing (a ball mill) - ingredients - the second ball mill (wet) - magnetic molding - sintering - clean grinding - the magnetization. Because the forming slurry contains water, the forming particles are easy to turn in the magnetic field, so it can obtain higher orientation than dry pressure, and its performance is higher BeiLun Meank, as an excellent permanent magnet company, offers a wide range of permanent magnet china for you to choose from.
