Detailed Product Description:
Item No.: Y25-Ferrite-5 Magnet Shape: Horseshoe / U-shaped Material: Hard Ferrite (Ceramic) Composite: Fe2O3 (BaCo3 or SrO3), Fe3O4 (SrCo3, SiO2) Type: anisotropic or isotropic Style: Sintered Permanent Magnet Grade(China Stardard): Y25 Detailed magnetic properties data: Residual Magnetic Flux Density (Br): 3.6-4.0 KGs (mT): 360-400 mT Intrinsic Coercivity Force (Hcj): 1.70-2.14 KOe 135-170 KA/m Coercivity Force (Hcb): 1.76-2.51 KOe 140-200 KA/m Energy Density (BH)max: 2.8-3.5 MGOe 22.5-28.0 KJ/m³ Operating Temperature: -40 °C to +250 °C Magnetisation Direction: Axial / Radially magnetized Size Can be customized according to customer drawings: Tolerance: +/-2% mm Delivery time 7-25 days Hard Ferrite/Ceramic magnets can be produced with either isotropic or anisotropic properties. The most common grades produced are C1, C5, and C8. C1 material exhibits the lowest energy product, however it is isotropic – indicating that it can be magnetized in any direction. It should be noted that slightly more magnetic strength will be realized when parts are magnetized through the pressing (usually the shortest) dimension. Grades 5 and 8 Ceramic materials are anisotropic, and must therefore be magnetized in the manufactured dimension. They exhibit higher levels of magnetic force than do “Ceramic 1†materials. Hard Ferrite magnets have excellent corrosion resistance and have normal operating capabilities between -40°C and +250°C. . At very low temperatures there is a risk of permanent demagnetization in magnet systems with low working points.
