Detailed Product Description:
Item No.: Y28H-Ferrite-5 Magnet Shape: Irregular Material: Hard Ferrite (Ceramic) Composite: Fe2O3 (BaCo3 or SrO3), Fe3O4 (SrCo3, SiO2) Type: anisotropic or isotropic Style: Sintered Permanent Magnet Grade(Chinese Stardard): Y28H Detailed magnetic properties data: Residual Magnetic Flux Density (Br): 3.8-4.0 KGs (mT): 380-400 mT Intrinsic Coercivity Force (Hcj): 3.01-3.27 KOe 240-260 KA/m Coercivity Force (Hcb): 3.14-3.52 KOe 250-280 KA/m Energy Density (BH)max: 3.3-3.8 MGOe 27.0-30.0 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 Ceramic magnet material is very hard and brittle. On average the material’s hardness is 7 on the Moh scale and conventional machine tools and cutters are not appropriate. Diamond tooling and some abrasives are the conventional means of fabrication for this magnet alloy. Most magnet materials are machined in the un-magnetized state. Once the fabrication and cleaning operation are complete the magnet is then magnetized to saturation. Ceramic magnets are fairly easy to magnetize and only require a reasonable magnetizing field. They are usually used in conjunction with a mild steel element such as a motor housing or backing-plate. Normally it is desirable to magnetize the Ceramic magnet installed on/in this element.
