Detailed Product Description:
Item No.: Y30BH-Ferrite-5 Magnet Shape: arc 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 Magnets of hard ferrite are the cheapest and best known types of magnets. Their raw materials are basically ferric oxide and barium or strontium carbonate. Magnets of ferrite can be isotrope or anisotrope energy density of the latter is about three times higher. We offer anisotrope ferrites only. You find different shapes: rings, block, discs and rods - and U-shapes (horseshoe magnets).
