Rubber magnets are permanent magnets made by mixing synthetic rubber with ferrite powder, then kneading and processing by extrusion molding. Rubber magnet materials offer the product designer a uniquely desirable combination of properties at lower cost than other magnet materials. Magnetic propertise are listed as below: FBA-1/FSA-2 Br:1600~1800Gs, bHc:1200~1400 Oe, iHc:1900~2000 Oe, (BH)max :0.6~0.8 MGOe FSR-3 Br:2400~2600Gs, bHc:2050~2250 Oe, iHc:>2600 Oe, (BH)max :1.4~1.6 MGOe
