Detailed Product Description:
Item No.: Y30BH-Ferrite-1 Magnet Shape: Ring / Tube Material: Hard Ferrite (Ceramic) Composite: Fe2O3 (BaCo3 or SrO3), Fe3O4 (SrCo3, SiO2) Type: anisotropic or isotropic Style: Sintered Permanent Magnet Grade(Chinese Stardard): Y30BH Detailed magnetic properties data: Residual Magnetic Flux Density (Br): 3.8-3.9 KGs (mT): 380-390 mT Intrinsic Coercivity Force (Hcj): 2.80-2.95 KOe 223-235 KA/m Coercivity Force (Hcb): 2.90-3.08 KOe 231-245 KA/m Energy Density (BH)max: 3.4-3.7 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 All ferrite ringmagnets on this page are axially magnetized. This means that the poles are respectively located on the flat circular surface. Ferrite or neodymium magnets? Compared to neodymium magnets, the adhesive force of ferrite magnets is much weaker. On the other hand, they are cheaper, suitable for outside use (rust-resistant) and can take heat up to 250 °C. If size and volume are less important than price, ferrite magnets can be a good alternative to neodymium magnets.
