Ferrite sintered magnet *High quality produced consistently in Japan from raw materials!
Solving issues such as large variations in magnetism and problems like cracks and chips! High-quality ferrite sintered magnets produced through consistent manufacturing from raw materials!
Sintered magnets are cost-effective magnets made primarily from iron(III) oxide (Fe2O3) and either barium carbonate (BaCO3) or strontium carbonate (SrCO3), produced using powder metallurgy methods. There are two types: "isotropic," which is pressed in a non-magnetic field, and "anisotropic" (both dry and wet), which is pressed in a magnetic field to impart magnetic directionality. Each type is categorized based on the magnetic characteristics shown in the magnetic property table. Thanks to the high coercivity characteristic of sintered magnets, they are less affected by external magnetic fields and self-demagnetization, and can accommodate flat or complex shapes! At Tokyo Ferrite, we conduct consistent production domestically from raw materials, ensuring high-quality manufacturing that addresses issues such as cracking and chipping. 【Features】 ■ Can be supplied stably and at low cost, offering excellent cost performance! ■ High coercivity makes them resistant to demagnetization, providing stable magnetic force! ■ Can achieve multi-pole magnetization on flat surfaces with 2 to over 10 poles, as well as on outer and inner circumferences! ■ We can also provide "pole anisotropic" and "radial magnets" as needed! *For more details, please refer to the catalog or feel free to contact us.

basic information
【We will be exhibiting at the New Value Creation Exhibition 2018】 We will be exhibiting from the booth of the Ibaraki Prefectural Small and Medium Enterprises Association. Dates: 2018/11/14 to 11/16 Time: 10:00 AM to 5:00 PM Venue: Tokyo Big Sight Please feel free to stop by our booth during this opportunity. 【Points to Note Regarding the Physical Properties of Sintered Magnets】 The temperature coefficient of magnetic flux density is relatively large, ranging from -0.18 to -0.19%/°C. Additionally, in anisotropic materials, as the temperature decreases, the coercive force also decreases at a rate of +0.35 to +0.5%/°C. In design, it is necessary to set the operating point of the magnet above the knee point of the demagnetization curve at low temperatures. *For more details, please refer to the catalog or feel free to contact us.
